Learn more."],"attrs_boilerpipe_text":"Some people can be depressed and not know it. Although well-known symptoms such as sadness or hopelessness can be easy to recognize, other signs of depression may be less obvious.\nAlthough some depression symptoms are obvious, there are many hidden signs of depression. However, it is important to note that other medical issues can also cause some of the same symptoms.\nThis article discusses some of the less obvious symptoms of depression. It also covers common causes of depression and what a person should do if they or a loved one experiences the following symptoms.\nEating too much or too little\ncan indicate\ndepression. Some people turn to food for comfort, while others lose their\nappetite\nor eat less due to low mood.\nThese changes in food intake can cause a person to gain or lose weight. They can also affect mood and energy levels.\nThere may also be physiological factors at play. For example,\nthere is a link\nbetween excess body fat and\nincreased inflammation\nin the body. This, in turn, may play a role in the development or severity of depression symptoms.\nThere is a strong connection between mood and sleep. A lack of sleep can contribute to\ndepression\n, and depression can make it more difficult to sleep.\nResearch\nsuggests that chronic\nsleep deprivation\ncan contribute to depression. This may be due to neurochemical changes in the brain.\nHowever, sleeping more than usual can also be a sign that a person may have depression.\nSome people with mood disorders may use alcohol or drugs to help them cope with negative emotions, such as sadness, loneliness, or hopelessness.\nThe\nAnxiety & Depression Association of America (ADAA)\nreports that in the United States, about 1 in 5 people with anxiety or a mood disorder such as depression also have an alcohol or\nsubstance use disorder\n. Conversely, the same proportion of those with an alcohol or substance use disorder also have a mood disorder.\nNegative self-talk is an inner dialogue that is damaging and self-critical. Many people with depression experience negative self-talk and default to harmful, critical thoughts toward themselves.\nAlthough there is limited research on the long-term effects of negative self-talk,\nresearch\nhas found that it has harmful effects on well-being and cognitive function.\nFeeling excessively tired is a very common symptom of depression. Some research suggests that\nmore than 90%\nof people with depression experience\nfatigue\n.\nAlthough everyone feels tired from time to time, people who have severe or persistent tiredness — especially if it accompanies other symptoms — may have hidden depression.\nSometimes, people refer to hidden depression as “\nsmiling depression\n.” The reason for this is that people who hide their symptoms\nmay ensure\nthat their face appears happy while in the company of others.\nHowever, it can be difficult to keep up with this forced happiness and positivity. Over time, the mask may slip, and a person may show signs of sadness, hopelessness, or loneliness.\nThere is a theory that people with depression may display a trait called “\ndepressive realism\n.” This means that they\nmay be more accurate\nin their view of events and the control they have over those events than people without depression.\nBeing more realistic or pessimistic than others may be one sign of depression, especially if the person has other possible symptoms of depression.\nWhen a person trails off during conversations or loses their train of thought, this can indicate issues with memory and\nconcentration\n. Such issues are a common symptom of depression.\nAn older\n2014 study\nsuggests that these difficulties with concentration and focus can worsen the social impact of depression by making work life and personal relationships more challenging.\nAdditionally, a\n2018 narrative review\nnotes that cognitive dysfunction is a key aspect of\nmajor depressive disorder (MDD)\n. This can significantly affect a person’s social life, returning to work, and workplace productivity.\nThe\nNational Institute of Mental Health\nlists a “loss of interest or pleasure in hobbies and activities” as one of the telltale symptoms of depression. Disinterest in activities that a person used to enjoy can be one of the first signs that other people notice when their loved one has depression.\nSome people with hidden depression experience personality changes. They may become more quiet and withdrawn, or they may be angry and irritable.\nMany people do not associate anger and irritability with depression, but these mood changes are not unusual among those with the condition. Instead of appearing sad, some people with hidden depression may display irritability and overt or suppressed anger.\nSome healthcare professionals consider changes in sex drive a key indicator when diagnosing episodes of depressive symptoms. In a\n2018 study\n, more severe depression was associated with more severe sexual dysfunction. This dysfunction included trouble with sexual function, desire, and satisfaction.\nThere are several reasons why a person’s\nlibido\nmight decrease when they have depression. These include:\nloss of interest in pleasurable activities, such as sex\nfatigue and low energy levels\nlow self-esteem\nScientists do not yet know the exact cause of depression. However, many experts think a combination of biological and environmental factors plays a role in its onset.\nPeople with symptoms of depression should consider seeking help from a healthcare professional, such as a doctor or psychotherapist. These professionals can help make a diagnosis and recommend a course of treatment.\nA person with depression may also wish to get support from loved ones.\nOther steps to manage depression might include:\nreducing stress, such as through\nmeditation\n, deep breathing exercises, or\nyoga\nimproving self-esteem through\npositive self-affirmations\nsocializing with others, although this can be challenging with depression\nengaging in activities that the person used to enjoy\nexercising\nregularly\neating a\nbalanced diet\nasking family or friends for support\njoining a\nsupport group\nBelow are some commonly asked questions about whether a person can be depressed and not know it.\nCan people be unaware that they have depression?\nIt is possible that a person may be depressed and not know it. Less obvious symptoms of depression include:\nweight changes\nsleep disturbances\nalcohol or drug use\nnegative self-talk\nfatigue\nloss of concentration\nlow sex drive\nIs there a silent depression?\nThere are many types of depression, including major depression and seasonal affective disorder.\nHidden depression, or “silent depression,” is not a medical diagnosis and refers to symptoms of depression that are less recognized by others.\nHow often does depression go unnoticed?\nAccording to\nolder research\n, around two-thirds of all cases of depression in the United States are undiagnosed.\nThe reasons for this include stigma, lack of perceived need, and affordability.\nNot everyone with depression will display the typical symptoms of sadness and despair. Sometimes, the only signs that a person may show are physical, such as fatigue or weight changes.\nOther signs of hidden depression can include using alcohol or drugs, being irritable or angry, and losing interest in pleasurable activities such as sex and hobbies.\nPeople concerned that a loved one has hidden depression should try talking with them about their symptoms and offering nonjudgmental support and advice. Individuals who suspect that they have depression should consider discussing it with a doctor or mental health professional.","attrs_markdown":"- Health Conditions\n  Health Conditions\n  \n  - [Alzheimer's & Dementia](https:\/\/www.medicalnewstoday.com\/alzheimers-and-dementia)\n  -

Although well-known symptoms such as sadness or hopelessness can be easy to recognize, other signs of depression may be less obvious.\n***\nAlthough some depression symptoms are obvious, there are many hidden signs of depression. However, it is important to note that other medical issues can also cause some of the same symptoms.\n\nThis article discusses some of the less obvious symptoms of depression. It also covers common causes of depression and what a person should do if they or a loved one experiences the following symptoms.\n\n![A man with hidden signs of depression sits on a basketball court](https:\/\/i0.wp.com\/post.medicalnewstoday.com\/wp-content\/uploads\/sites\/3\/2023\/10\/hidden_signs_depression_fatigue_lack_of_interest_1296x728_header-1024x575.jpg?w=1155&h=1528)\n\n[Share on Pinterest](https:\/\/www.pinterest.com\/pin\/create\/button\/?url=https%3A%2F%2Fwww.medicalnewstoday.com%2Farticles%2F325513&media=https%3A%2F%2Fpost.medicalnewstoday.com%2Fwp-content%2Fuploads%2Fsites%2F3%2F2023%2F10%2Fhidden_signs_depression_fatigue_lack_of_interest_1296x728_header-1024x575.jpg&description=Hidden%20signs%20of%20depression%3A%20How%20to%20spot%20them%20and%20what%20to%20do \"Share on Pinterest\")\n\nmihailomilovanovic\/Getty Images\n\n## [Appetite and weight changes]()\nEating too much or too little [can indicate](https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC6937709\/) depression. Some people turn to food for comfort, while others lose their [appetite](https:\/\/www.medicalnewstoday.com\/articles\/appetite) or eat less due to low mood.\n\nThese changes in food intake can cause a person to gain or lose weight. They can also affect mood and energy levels.\n\nThere may also be physiological factors at play. For example, [there is a link](https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC5507106\/) between excess body fat and [increased inflammation](https:\/\/www.jneuropsychiatry.org\/peer-review\/depression-and-inflammation-disentangling-a-clear-yet-complex-and-multifaceted-link.html) in the body. This, in turn, may play a role in the development or severity of depression symptoms.\n\n## [Changes in sleep habits]()\nThere is a strong connection between mood and sleep. A lack of sleep can contribute to [depression](https:\/\/www.medicalnewstoday.com\/articles\/8933), and depression can make it more difficult to sleep.\n\n[Research](https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4318605\/) suggests that chronic [sleep deprivation](https:\/\/www.medicalnewstoday.com\/articles\/307334) can contribute to depression. This may be due to neurochemical changes in the brain.\n\n*However, sleeping more than usual can also be a sign that a person may have depression.*\n\n## [Alcohol or drug use]()\nSome people with mood disorders may use alcohol or drugs to help them cope with negative emotions, such as sadness, loneliness, or hopelessness.\n\nThe [Anxiety & Depression Association of America (ADAA)](https:\/\/adaa.org\/understanding-anxiety\/related-illnesses\/substance-abuse) reports that in the United States, about 1 in 5 people with anxiety or a mood disorder such as depression also have an alcohol or [substance use disorder](https:\/\/www.medicalnewstoday.com\/articles\/depression-and-substance-abuse). Conversely, the same proportion of those with an alcohol or substance use disorder also have a mood disorder.\n\n## [Negative self-talk]()\nNegative self-talk is an inner dialogue that is damaging and self-critical. Many people with depression experience negative self-talk and default to harmful, critical thoughts toward themselves.\n\nAlthough there is limited research on the long-term effects of negative self-talk, [research](https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC8295361\/) has found that it has harmful effects on well-being and cognitive function.\n\n## [Fatigue]()\nFeeling excessively tired is a very common symptom of depression. Some research suggests that [more than 90%](https:\/\/link.springer.com\/article\/10.1007\/s40263-018-0490-z) of people with depression experience [fatigue](https:\/\/www.medicalnewstoday.com\/articles\/248002.php \"Fatigue: Why am I so tired and what can I do about it?\").\n\nAlthough everyone feels tired from time to time, people who have severe or persistent tiredness — especially if it accompanies other symptoms — may have hidden depression.\n\n## [Forced happiness]()\nSometimes, people refer to hidden depression as “[smiling depression](https:\/\/www.medicalnewstoday.com\/articles\/smiling-depression).” The reason for this is that people who hide their symptoms [may ensure](https:\/\/www.nami.org\/Blogs\/NAMI-Blog\/September-2016\/What-You-Need-to-Know-About-Smiling-Depression) that their face appears happy while in the company of others.\n\nHowever, it can be difficult to keep up with this forced happiness and positivity. Over time, the mask may slip, and a person may show signs of sadness, hopelessness, or loneliness.\n\n## [Less optimistic than others]()\nThere is a theory that people with depression may display a trait called “[depressive realism](https:\/\/www.medicalnewstoday.com\/articles\/depressive-realism).” This means that they [may be more accurate](https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4323577\/) in their view of events and the control they have over those events than people without depression.\n\nBeing more realistic or pessimistic than others may be one sign of depression, especially if the person has other possible symptoms of depression.\n\n## [Loss of concentration]()\nWhen a person trails off during conversations or loses their train of thought, this can indicate issues with memory and [concentration](https:\/\/www.medicalnewstoday.com\/articles\/320165). Such issues are a common symptom of depression.\n\nAn older [2014 study](https:\/\/journals.plos.org\/plosone\/article?id=10.1371\/journal.pone.0090311) suggests that these difficulties with concentration and focus can worsen the social impact of depression by making work life and personal relationships more challenging.\n\nAdditionally, a [2018 narrative review](https:\/\/www.frontiersin.org\/articles\/10.3389\/fpsyt.2018.00655\/full#h4) notes that cognitive dysfunction is a key aspect of [major depressive disorder (MDD)](https:\/\/www.medicalnewstoday.com\/articles\/major-depressive-disorder). This can significantly affect a person’s social life, returning to work, and workplace productivity.\n\n## [Disinterest in hobbies]()\nThe [National Institute of Mental Health](https:\/\/www.nimh.nih.gov\/health\/topics\/depression\/index.shtml) lists a “loss of interest or pleasure in hobbies and activities” as one of the telltale symptoms of depression. Disinterest in activities that a person used to enjoy can be one of the first signs that other people notice when their loved one has depression.\n\n## [Physical pains and health disorders]()\nDepression is a [mental health](https:\/\/www.medicalnewstoday.com\/articles\/154543.php \"What is mental health?\") condition, but it can also have physical consequences. In addition to weight changes and fatigue, other physical symptoms of hidden depression to look out for [include](https:\/\/www.nimh.nih.gov\/health\/topics\/depression):\n\n- [headache](https:\/\/www.medicalnewstoday.com\/articles\/73936.php \"What is causing this headache?\")\n- [tight chest](https:\/\/www.medicalnewstoday.com\/articles\/324537)\n- [racing heart](https:\/\/www.medicalnewstoday.com\/articles\/why-is-my-heart-beating-fast-for-no-reason)\n- [aches](https:\/\/www.medicalnewstoday.com\/articles\/319985) and pains\n- [digestive problems](https:\/\/www.medicalnewstoday.com\/articles\/digestive-problems)\n\n## [Personality differences]()\nSome people with hidden depression experience personality changes. They may become more quiet and withdrawn, or they may be angry and irritable.\n\nMany people do not associate anger and irritability with depression, but these mood changes are not unusual among those with the condition. Instead of appearing sad, some people with hidden depression may display irritability and overt or suppressed anger.\n\n## [Low sex drive]()\nSome healthcare professionals consider changes in sex drive a key indicator when diagnosing episodes of depressive symptoms. In a [2018 study](https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC6278224\/), more severe depression was associated with more severe sexual dysfunction. This dysfunction included trouble with sexual function, desire, and satisfaction.\n\nThere are several reasons why a person’s [libido](https:\/\/www.medicalnewstoday.com\/articles\/323918) might decrease when they have depression. These include:\n\n- loss of interest in pleasurable activities, such as sex\n- fatigue and low energy levels\n- [low self-esteem](https:\/\/www.medicalnewstoday.com\/articles\/i-have-lost-my-confidence-and-self-esteem)\n\n## [Common causes of depression]()\nScientists do not yet know the exact cause of depression. However, many experts think a combination of biological and environmental factors plays a role in its onset.\n\n[Learn more about common causes of depression here](https:\/\/www.medicalnewstoday.com\/articles\/8933).\n\n## [What to do if you think you have hidden depression]()\nPeople with symptoms of depression should consider seeking help from a healthcare professional, such as a doctor or psychotherapist. These professionals can help make a diagnosis and recommend a course of treatment.\n\nA person with depression may also wish to get support from loved ones.\n\nOther steps to manage depression might include:\n\n- reducing stress, such as through [meditation](https:\/\/www.medicalnewstoday.com\/articles\/320392), deep breathing exercises, or [yoga](https:\/\/www.medicalnewstoday.com\/articles\/286745.php \"How does yoga work?\")\n- improving self-esteem through [positive self-affirmations](https:\/\/www.medicalnewstoday.com\/articles\/positive-self-talk)\n- socializing with others, although this can be challenging with depression\n- engaging in activities that the person used to enjoy\n- [exercising](https:\/\/www.medicalnewstoday.com\/articles\/153390) regularly\n- eating a [balanced diet](https:\/\/www.medicalnewstoday.com\/articles\/324093)\n- asking family or friends for support\n- joining a [support group](https:\/\/www.medicalnewstoday.com\/articles\/depression-support-groups)\n\nSources of help for people with mental health conditions and mood disorders include the [ADAA’s website](https:\/\/adaa.org\/) and [Mental Health America’s list of support groups](http:\/\/www.mentalhealthamerica.net\/find-support-groups).\n\n### Help is out there\nIf you or someone you know is in crisis and considering suicide or self-harm, please seek support:\n\n- Call or text the [988 Lifeline](https:\/\/988lifeline.org\/) at 988 or chat at 988lifeline.org. Caring counselors are available to listen and provide free and confidential support 24\/7.\n- Text HOME to the [Crisis Text Line](https:\/\/www.crisistextline.org\/?gclid=EAIaIQobChMIsPDQrdXH5wIVBRx9Ch1YdQjIEAAYASAAEgJ_1_D_BwE) at 741741 to connect with a volunteer crisis counselor for free and confidential support 24\/7.\n- Not in the United States? Find a helpline in your country with [Befrienders Worldwide](https:\/\/www.befrienders.org\/).\n- Call 911 or your local emergency services number if you feel safe to do so.\n\nIf you’re calling on behalf of someone else, stay with them until help arrives. You may remove weapons or substances that can cause harm if you can do so safely.\n\nIf you’re not in the same household, stay on the phone with them until help arrives.\n\n## [Frequently asked questions]()\nBelow are some commonly asked questions about whether a person can be depressed and not know it.\n\n### Can people be unaware that they have depression?\nIt is possible that a person may be depressed and not know it. Less obvious symptoms of depression include:\n\n- weight changes\n- sleep disturbances\n- alcohol or drug use\n- negative self-talk\n- fatigue\n- loss of concentration\n- low sex drive\n### Is there a silent depression?\nThere are many types of depression, including major depression and seasonal affective disorder.\n\nHidden depression, or “silent depression,” is not a medical diagnosis and refers to symptoms of depression that are less recognized by others.\n\n### How often does depression go unnoticed?\nAccording to [older research](https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC5769115\/), around two-thirds of all cases of depression in the United States are undiagnosed.\n\nThe reasons for this include stigma, lack of perceived need, and affordability.\n\n## [Summary]()\nNot everyone with depression will display the typical symptoms of sadness and despair. Sometimes, the only signs that a person may show are physical, such as fatigue or weight changes.\n\nOther signs of hidden depression can include using alcohol or drugs, being irritable or angry, and losing interest in pleasurable activities such as sex and hobbies.\n\nPeople concerned that a loved one has hidden depression should try talking with them about their symptoms and offering nonjudgmental support and advice. Individuals who suspect that they have depression should consider discussing it with a doctor or mental health professional.\n\n[Read the article in Spanish.](https:\/\/www.medicalnewstoday.com\/articles\/es\/signos-de-depresion)\n\n- [Depression](https:\/\/www.medicalnewstoday.com\/categories\/depression)\n- [Mental Health](https:\/\/www.medicalnewstoday.com\/categories\/mental-health)\n- [Psychology \/ Psychiatry](https:\/\/www.medicalnewstoday.com\/categories\/psychology-psychiatry)\n\n### How we reviewed this article:\nSources\n\nMedical News Today has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical journals and associations.

Although well-known symptoms such as sadness or hopelessness can be easy to recognize, other signs of depression may be less obvious.\n\nAlthough some depression symptoms are obvious, there are many hidden signs of depression. However, it is important to note that other medical issues can also cause some of the same symptoms.\n\nThis article discusses some of the less obvious symptoms of depression. It also covers common causes of depression and what a person should do if they or a loved one experiences the following symptoms.\n\nEating too much or too little [can indicate](https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC6937709\/) depression. Some people turn to food for comfort, while others lose their [appetite](https:\/\/www.medicalnewstoday.com\/articles\/appetite) or eat less due to low mood.\n\nThese changes in food intake can cause a person to gain or lose weight. They can also affect mood and energy levels.\n\nThere may also be physiological factors at play. For example, [there is a link](https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC5507106\/) between excess body fat and [increased inflammation](https:\/\/www.jneuropsychiatry.org\/peer-review\/depression-and-inflammation-disentangling-a-clear-yet-complex-and-multifaceted-link.html) in the body. This, in turn, may play a role in the development or severity of depression symptoms.\n\nThere is a strong connection between mood and sleep. A lack of sleep can contribute to [depression](https:\/\/www.medicalnewstoday.com\/articles\/8933), and depression can make it more difficult to sleep.\n\n[Research](https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4318605\/) suggests that chronic [sleep deprivation](https:\/\/www.medicalnewstoday.com\/articles\/307334) can contribute to depression. This may be due to neurochemical changes in the brain.\n\n*However, sleeping more than usual can also be a sign that a person may have depression.*\n\nSome people with mood disorders may use alcohol or drugs to help them cope with negative emotions, such as sadness, loneliness, or hopelessness.\n\nThe [Anxiety & Depression Association of America (ADAA)](https:\/\/adaa.org\/understanding-anxiety\/related-illnesses\/substance-abuse) reports that in the United States, about 1 in 5 people with anxiety or a mood disorder such as depression also have an alcohol or [substance use disorder](https:\/\/www.medicalnewstoday.com\/articles\/depression-and-substance-abuse). Conversely, the same proportion of those with an alcohol or substance use disorder also have a mood disorder.\n\nNegative self-talk is an inner dialogue that is damaging and self-critical. Many people with depression experience negative self-talk and default to harmful, critical thoughts toward themselves.\n\nAlthough there is limited research on the long-term effects of negative self-talk, [research](https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC8295361\/) has found that it has harmful effects on well-being and cognitive function.\n\nFeeling excessively tired is a very common symptom of depression. Some research suggests that [more than 90%](https:\/\/link.springer.com\/article\/10.1007\/s40263-018-0490-z) of people with depression experience [fatigue](https:\/\/www.medicalnewstoday.com\/articles\/248002.php \"Fatigue: Why am I so tired and what can I do about it?\").\n\nAlthough everyone feels tired from time to time, people who have severe or persistent tiredness — especially if it accompanies other symptoms — may have hidden depression.\n\nSometimes, people refer to hidden depression as “[smiling depression](https:\/\/www.medicalnewstoday.com\/articles\/smiling-depression).” The reason for this is that people who hide their symptoms [may ensure](https:\/\/www.nami.org\/Blogs\/NAMI-Blog\/September-2016\/What-You-Need-to-Know-About-Smiling-Depression) that their face appears happy while in the company of others.\n\nHowever, it can be difficult to keep up with this forced happiness and positivity. Over time, the mask may slip, and a person may show signs of sadness, hopelessness, or loneliness.\n\nThere is a theory that people with depression may display a trait called “[depressive realism](https:\/\/www.medicalnewstoday.com\/articles\/depressive-realism).” This means that they [may be more accurate](https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4323577\/) in their view of events and the control they have over those events than people without depression.\n\nBeing more realistic or pessimistic than others may be one sign of depression, especially if the person has other possible symptoms of depression.\n\nWhen a person trails off during conversations or loses their train of thought, this can indicate issues with memory and [concentration](https:\/\/www.medicalnewstoday.com\/articles\/320165). Such issues are a common symptom of depression.\n\nAn older [2014 study](https:\/\/journals.plos.org\/plosone\/article?id=10.1371\/journal.pone.0090311) suggests that these difficulties with concentration and focus can worsen the social impact of depression by making work life and personal relationships more challenging.\n\nAdditionally, a [2018 narrative review](https:\/\/www.frontiersin.org\/articles\/10.3389\/fpsyt.2018.00655\/full#h4) notes that cognitive dysfunction is a key aspect of [major depressive disorder (MDD)](https:\/\/www.medicalnewstoday.com\/articles\/major-depressive-disorder). This can significantly affect a person’s social life, returning to work, and workplace productivity.\n\nThe [National Institute of Mental Health](https:\/\/www.nimh.nih.gov\/health\/topics\/depression\/index.shtml) lists a “loss of interest or pleasure in hobbies and activities” as one of the telltale symptoms of depression. Disinterest in activities that a person used to enjoy can be one of the first signs that other people notice when their loved one has depression.\n\nSome people with hidden depression experience personality changes. They may become more quiet and withdrawn, or they may be angry and irritable.\n\nMany people do not associate anger and irritability with depression, but these mood changes are not unusual among those with the condition. Instead of appearing sad, some people with hidden depression may display irritability and overt or suppressed anger.\n\nSome healthcare professionals consider changes in sex drive a key indicator when diagnosing episodes of depressive symptoms. In a [2018 study](https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC6278224\/), more severe depression was associated with more severe sexual dysfunction. This dysfunction included trouble with sexual function, desire, and satisfaction.\n\nThere are several reasons why a person’s [libido](https:\/\/www.medicalnewstoday.com\/articles\/323918) might decrease when they have depression. These include:\n\n- loss of interest in pleasurable activities, such as sex\n- fatigue and low energy levels\n- [low self-esteem](https:\/\/www.medicalnewstoday.com\/articles\/i-have-lost-my-confidence-and-self-esteem)\n\nScientists do not yet know the exact cause of depression.

Although well-known symptoms such as sadness or hopelessness can be easy to recognize, other signs of depression may be less obvious. *** Although some depression symptoms are obvious, there are many hidden signs of depression. However, it is important to note that other medical issues can also cause some of the same symptoms. This article discusses some of the less obvious symptoms of depression. It also covers common causes of depression and what a person should do if they or a loved one experiences the following symptoms. ![A man with hidden signs of depression sits on a basketball court](https://i0.wp.com/post.medicalnewstoday.com/wp-content/uploads/sites/3/2023/10/hidden_signs_depression_fatigue_lack_of_interest_1296x728_header-1024x575.jpg?w=1155&h=1528) [Share on Pinterest](https://www.pinterest.com/pin/create/button/?url=https%3A%2F%2Fwww.medicalnewstoday.com%2Farticles%2F325513&media=https%3A%2F%2Fpost.medicalnewstoday.com%2Fwp-content%2Fuploads%2Fsites%2F3%2F2023%2F10%2Fhidden_signs_depression_fatigue_lack_of_interest_1296x728_header-1024x575.jpg&description=Hidden%20signs%20of%20depression%3A%20How%20to%20spot%20them%20and%20what%20to%20do "Share on Pinterest") mihailomilovanovic/Getty Images ## [Appetite and weight changes]() Eating too much or too little [can indicate](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6937709/) depression. Some people turn to food for comfort, while others lose their [appetite](https://www.medicalnewstoday.com/articles/appetite) or eat less due to low mood. These changes in food intake can cause a person to gain or lose weight. They can also affect mood and energy levels. There may also be physiological factors at play. For example, [there is a link](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5507106/) between excess body fat and [increased inflammation](https://www.jneuropsychiatry.org/peer-review/depression-and-inflammation-disentangling-a-clear-yet-complex-and-multifaceted-link.html) in the body. This, in turn, may play a role in the development or severity of depression symptoms. ## [Changes in sleep habits]() There is a strong connection between mood and sleep. A lack of sleep can contribute to [depression](https://www.medicalnewstoday.com/articles/8933), and depression can make it more difficult to sleep. [Research](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4318605/) suggests that chronic [sleep deprivation](https://www.medicalnewstoday.com/articles/307334) can contribute to depression. This may be due to neurochemical changes in the brain. However, sleeping more than usual can also be a sign that a person may have depression. ## [Alcohol or drug use]() Some people with mood disorders may use alcohol or drugs to help them cope with negative emotions, such as sadness, loneliness, or hopelessness. The [Anxiety & Depression Association of America (ADAA)](https://adaa.org/understanding-anxiety/related-illnesses/substance-abuse) reports that in the United States, about 1 in 5 people with anxiety or a mood disorder such as depression also have an alcohol or [substance use disorder](https://www.medicalnewstoday.com/articles/depression-and-substance-abuse). Conversely, the same proportion of those with an alcohol or substance use disorder also have a mood disorder. ## [Negative self-talk]() Negative self-talk is an inner dialogue that is damaging and self-critical. Many people with depression experience negative self-talk and default to harmful, critical thoughts toward themselves. Although there is limited research on the long-term effects of negative self-talk, [research](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8295361/) has found that it has harmful effects on well-being and cognitive function. ## [Fatigue]() Feeling excessively tired is a very common symptom of depression. Some research suggests that [more than 90%](https://link.springer.com/article/10.1007/s40263-018-0490-z) of people with depression experience [fatigue](https://www.medicalnewstoday.com/articles/248002.php "Fatigue: Why am I so tired and what can I do about it?"). Although everyone feels tired from time to time, people who have severe or persistent tiredness — especially if it accompanies other symptoms — may have hidden depression. ## [Forced happiness]() Sometimes, people refer to hidden depression as “[smiling depression](https://www.medicalnewstoday.com/articles/smiling-depression).” The reason for this is that people who hide their symptoms [may ensure](https://www.nami.org/Blogs/NAMI-Blog/September-2016/What-You-Need-to-Know-About-Smiling-Depression) that their face appears happy while in the company of others. However, it can be difficult to keep up with this forced happiness and positivity. Over time, the mask may slip, and a person may show signs of sadness, hopelessness, or loneliness. ## [Less optimistic than others]() There is a theory that people with depression may display a trait called “[depressive realism](https://www.medicalnewstoday.com/articles/depressive-realism).” This means that they [may be more accurate](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4323577/) in their view of events and the control they have over those events than people without depression. Being more realistic or pessimistic than others may be one sign of depression, especially if the person has other possible symptoms of depression. ## [Loss of concentration]() When a person trails off during conversations or loses their train of thought, this can indicate issues with memory and [concentration](https://www.medicalnewstoday.com/articles/320165). Such issues are a common symptom of depression. An older [2014 study](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0090311) suggests that these difficulties with concentration and focus can worsen the social impact of depression by making work life and personal relationships more challenging. Additionally, a [2018 narrative review](https://www.frontiersin.org/articles/10.3389/fpsyt.2018.00655/full#h4) notes that cognitive dysfunction is a key aspect of [major depressive disorder (MDD)](https://www.medicalnewstoday.com/articles/major-depressive-disorder). This can significantly affect a person’s social life, returning to work, and workplace productivity. ## [Disinterest in hobbies]() The [National Institute of Mental Health](https://www.nimh.nih.gov/health/topics/depression/index.shtml) lists a “loss of interest or pleasure in hobbies and activities” as one of the telltale symptoms of depression. Disinterest in activities that a person used to enjoy can be one of the first signs that other people notice when their loved one has depression. ## [Physical pains and health disorders]() Depression is a [mental health](https://www.medicalnewstoday.com/articles/154543.php "What is mental health?") condition, but it can also have physical consequences. In addition to weight changes and fatigue, other physical symptoms of hidden depression to look out for [include](https://www.nimh.nih.gov/health/topics/depression): - [headache](https://www.medicalnewstoday.com/articles/73936.php "What is causing this headache?") - [tight chest](https://www.medicalnewstoday.com/articles/324537) - [racing heart](https://www.medicalnewstoday.com/articles/why-is-my-heart-beating-fast-for-no-reason) - [aches](https://www.medicalnewstoday.com/articles/319985) and pains - [digestive problems](https://www.medicalnewstoday.com/articles/digestive-problems) ## [Personality differences]() Some people with hidden depression experience personality changes. They may become more quiet and withdrawn, or they may be angry and irritable. Many people do not associate anger and irritability with depression, but these mood changes are not unusual among those with the condition. Instead of appearing sad, some people with hidden depression may display irritability and overt or suppressed anger. ## [Low sex drive]() Some healthcare professionals consider changes in sex drive a key indicator when diagnosing episodes of depressive symptoms. In a [2018 study](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6278224/), more severe depression was associated with more severe sexual dysfunction. This dysfunction included trouble with sexual function, desire, and satisfaction. There are several reasons why a person’s [libido](https://www.medicalnewstoday.com/articles/323918) might decrease when they have depression. These include: - loss of interest in pleasurable activities, such as sex - fatigue and low energy levels - [low self-esteem](https://www.medicalnewstoday.com/articles/i-have-lost-my-confidence-and-self-esteem) ## [Common causes of depression]() Scientists do not yet know the exact cause of depression. However, many experts think a combination of biological and environmental factors plays a role in its onset. [Learn more about common causes of depression here](https://www.medicalnewstoday.com/articles/8933). ## [What to do if you think you have hidden depression]() People with symptoms of depression should consider seeking help from a healthcare professional, such as a doctor or psychotherapist. These professionals can help make a diagnosis and recommend a course of treatment. A person with depression may also wish to get support from loved ones. Other steps to manage depression might include: - reducing stress, such as through [meditation](https://www.medicalnewstoday.com/articles/320392), deep breathing exercises, or [yoga](https://www.medicalnewstoday.com/articles/286745.php "How does yoga work?") - improving self-esteem through [positive self-affirmations](https://www.medicalnewstoday.com/articles/positive-self-talk) - socializing with others, although this can be challenging with depression - engaging in activities that the person used to enjoy - [exercising](https://www.medicalnewstoday.com/articles/153390) regularly - eating a [balanced diet](https://www.medicalnewstoday.com/articles/324093) - asking family or friends for support - joining a [support group](https://www.medicalnewstoday.com/articles/depression-support-groups) Sources of help for people with mental health conditions and mood disorders include the [ADAA’s website](https://adaa.org/) and [Mental Health America’s list of support groups](http://www.mentalhealthamerica.net/find-support-groups). ### Help is out there If you or someone you know is in crisis and considering suicide or self-harm, please seek support: - Call or text the [988 Lifeline](https://988lifeline.org/) at 988 or chat at 988lifeline.org. Caring counselors are available to listen and provide free and confidential support 24/7. - Text HOME to the [Crisis Text Line](https://www.crisistextline.org/?gclid=EAIaIQobChMIsPDQrdXH5wIVBRx9Ch1YdQjIEAAYASAAEgJ_1_D_BwE) at 741741 to connect with a volunteer crisis counselor for free and confidential support 24/7. - Not in the United States? Find a helpline in your country with [Befrienders Worldwide](https://www.befrienders.org/). - Call 911 or your local emergency services number if you feel safe to do so. If you’re calling on behalf of someone else, stay with them until help arrives. You may remove weapons or substances that can cause harm if you can do so safely. If you’re not in the same household, stay on the phone with them until help arrives. ## [Frequently asked questions]() Below are some commonly asked questions about whether a person can be depressed and not know it. ### Can people be unaware that they have depression? It is possible that a person may be depressed and not know it. Less obvious symptoms of depression include: - weight changes - sleep disturbances - alcohol or drug use - negative self-talk - fatigue - loss of concentration - low sex drive ### Is there a silent depression? There are many types of depression, including major depression and seasonal affective disorder. Hidden depression, or “silent depression,” is not a medical diagnosis and refers to symptoms of depression that are less recognized by others. ### How often does depression go unnoticed? According to [older research](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5769115/), around two-thirds of all cases of depression in the United States are undiagnosed. The reasons for this include stigma, lack of perceived need, and affordability. ## [Summary]() Not everyone with depression will display the typical symptoms of sadness and despair. Sometimes, the only signs that a person may show are physical, such as fatigue or weight changes. Other signs of hidden depression can include using alcohol or drugs, being irritable or angry, and losing interest in pleasurable activities such as sex and hobbies. People concerned that a loved one has hidden depression should try talking with them about their symptoms and offering nonjudgmental support and advice. Individuals who suspect that they have depression should consider discussing it with a doctor or mental health professional.

Readable Markdown	Some people can be depressed and not know it. Although well-known symptoms such as sadness or hopelessness can be easy to recognize, other signs of depression may be less obvious. Although some depression symptoms are obvious, there are many hidden signs of depression. However, it is important to note that other medical issues can also cause some of the same symptoms. This article discusses some of the less obvious symptoms of depression. It also covers common causes of depression and what a person should do if they or a loved one experiences the following symptoms. Eating too much or too little [can indicate](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6937709/) depression. Some people turn to food for comfort, while others lose their [appetite](https://www.medicalnewstoday.com/articles/appetite) or eat less due to low mood. These changes in food intake can cause a person to gain or lose weight. They can also affect mood and energy levels. There may also be physiological factors at play. For example, [there is a link](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5507106/) between excess body fat and [increased inflammation](https://www.jneuropsychiatry.org/peer-review/depression-and-inflammation-disentangling-a-clear-yet-complex-and-multifaceted-link.html) in the body. This, in turn, may play a role in the development or severity of depression symptoms. There is a strong connection between mood and sleep. A lack of sleep can contribute to [depression](https://www.medicalnewstoday.com/articles/8933), and depression can make it more difficult to sleep. [Research](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4318605/) suggests that chronic [sleep deprivation](https://www.medicalnewstoday.com/articles/307334) can contribute to depression. This may be due to neurochemical changes in the brain. However, sleeping more than usual can also be a sign that a person may have depression. Some people with mood disorders may use alcohol or drugs to help them cope with negative emotions, such as sadness, loneliness, or hopelessness. The [Anxiety & Depression Association of America (ADAA)](https://adaa.org/understanding-anxiety/related-illnesses/substance-abuse) reports that in the United States, about 1 in 5 people with anxiety or a mood disorder such as depression also have an alcohol or [substance use disorder](https://www.medicalnewstoday.com/articles/depression-and-substance-abuse). Conversely, the same proportion of those with an alcohol or substance use disorder also have a mood disorder. Negative self-talk is an inner dialogue that is damaging and self-critical. Many people with depression experience negative self-talk and default to harmful, critical thoughts toward themselves. Although there is limited research on the long-term effects of negative self-talk, [research](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8295361/) has found that it has harmful effects on well-being and cognitive function. Feeling excessively tired is a very common symptom of depression. Some research suggests that [more than 90%](https://link.springer.com/article/10.1007/s40263-018-0490-z) of people with depression experience [fatigue](https://www.medicalnewstoday.com/articles/248002.php "Fatigue: Why am I so tired and what can I do about it?"). Although everyone feels tired from time to time, people who have severe or persistent tiredness — especially if it accompanies other symptoms — may have hidden depression. Sometimes, people refer to hidden depression as “[smiling depression](https://www.medicalnewstoday.com/articles/smiling-depression).” The reason for this is that people who hide their symptoms [may ensure](https://www.nami.org/Blogs/NAMI-Blog/September-2016/What-You-Need-to-Know-About-Smiling-Depression) that their face appears happy while in the company of others. However, it can be difficult to keep up with this forced happiness and positivity. Over time, the mask may slip, and a person may show signs of sadness, hopelessness, or loneliness. There is a theory that people with depression may display a trait called “[depressive realism](https://www.medicalnewstoday.com/articles/depressive-realism).” This means that they [may be more accurate](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4323577/) in their view of events and the control they have over those events than people without depression. Being more realistic or pessimistic than others may be one sign of depression, especially if the person has other possible symptoms of depression. When a person trails off during conversations or loses their train of thought, this can indicate issues with memory and [concentration](https://www.medicalnewstoday.com/articles/320165). Such issues are a common symptom of depression. An older [2014 study](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0090311) suggests that these difficulties with concentration and focus can worsen the social impact of depression by making work life and personal relationships more challenging. Additionally, a [2018 narrative review](https://www.frontiersin.org/articles/10.3389/fpsyt.2018.00655/full#h4) notes that cognitive dysfunction is a key aspect of [major depressive disorder (MDD)](https://www.medicalnewstoday.com/articles/major-depressive-disorder). This can significantly affect a person’s social life, returning to work, and workplace productivity. The [National Institute of Mental Health](https://www.nimh.nih.gov/health/topics/depression/index.shtml) lists a “loss of interest or pleasure in hobbies and activities” as one of the telltale symptoms of depression. Disinterest in activities that a person used to enjoy can be one of the first signs that other people notice when their loved one has depression. Some people with hidden depression experience personality changes. They may become more quiet and withdrawn, or they may be angry and irritable. Many people do not associate anger and irritability with depression, but these mood changes are not unusual among those with the condition. Instead of appearing sad, some people with hidden depression may display irritability and overt or suppressed anger. Some healthcare professionals consider changes in sex drive a key indicator when diagnosing episodes of depressive symptoms. In a [2018 study](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6278224/), more severe depression was associated with more severe sexual dysfunction. This dysfunction included trouble with sexual function, desire, and satisfaction. There are several reasons why a person’s [libido](https://www.medicalnewstoday.com/articles/323918) might decrease when they have depression. These include: - loss of interest in pleasurable activities, such as sex - fatigue and low energy levels - [low self-esteem](https://www.medicalnewstoday.com/articles/i-have-lost-my-confidence-and-self-esteem) Scientists do not yet know the exact cause of depression. However, many experts think a combination of biological and environmental factors plays a role in its onset. People with symptoms of depression should consider seeking help from a healthcare professional, such as a doctor or psychotherapist. These professionals can help make a diagnosis and recommend a course of treatment. A person with depression may also wish to get support from loved ones. Other steps to manage depression might include: - reducing stress, such as through [meditation](https://www.medicalnewstoday.com/articles/320392), deep breathing exercises, or [yoga](https://www.medicalnewstoday.com/articles/286745.php "How does yoga work?") - improving self-esteem through [positive self-affirmations](https://www.medicalnewstoday.com/articles/positive-self-talk) - socializing with others, although this can be challenging with depression - engaging in activities that the person used to enjoy - [exercising](https://www.medicalnewstoday.com/articles/153390) regularly - eating a [balanced diet](https://www.medicalnewstoday.com/articles/324093) - asking family or friends for support - joining a [support group](https://www.medicalnewstoday.com/articles/depression-support-groups) Below are some commonly asked questions about whether a person can be depressed and not know it. Can people be unaware that they have depression? It is possible that a person may be depressed and not know it. Less obvious symptoms of depression include: - weight changes - sleep disturbances - alcohol or drug use - negative self-talk - fatigue - loss of concentration - low sex drive Is there a silent depression? There are many types of depression, including major depression and seasonal affective disorder. Hidden depression, or “silent depression,” is not a medical diagnosis and refers to symptoms of depression that are less recognized by others. How often does depression go unnoticed? According to [older research](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5769115/), around two-thirds of all cases of depression in the United States are undiagnosed. The reasons for this include stigma, lack of perceived need, and affordability. Not everyone with depression will display the typical symptoms of sadness and despair. Sometimes, the only signs that a person may show are physical, such as fatigue or weight changes. Other signs of hidden depression can include using alcohol or drugs, being irritable or angry, and losing interest in pleasurable activities such as sex and hobbies. People concerned that a loved one has hidden depression should try talking with them about their symptoms and offering nonjudgmental support and advice. Individuals who suspect that they have depression should consider discussing it with a doctor or mental health professional.
