Common causes include viruses, bacteria, and parasites.\nDiarrhea is characterized by loose or watery stools. Most cases of diarrhea are due to bacteria, viruses, or parasites. Digestive disorders can also cause chronic diarrhea.\nThis article looks at the causes and treatments of diarrhea. It also looks at symptoms, diagnosis, prevention, and when to see a doctor.\nMany cases of diarrhea are due to an infection or disruption of the gastrointestinal tract.\nCommon causes\nof acute diarrhea include:\nfood poisoning\nviral gastroenteritis\nmedicine side effects\nChronic diarrhea\nConditions such as\nirritable bowel syndrome (IBS)\nare a common causes of “functional” chronic diarrhea.\nThis means that although all the digestive organs appear normal, they are not functioning as they ideally should.\nSome other major causes of chronic diarrhea include:\nMicroscopic colitis:\nThis is a persistent type of diarrhea that usually affects older adults. It develops due to inflammation and occurs often during the night.\nMalabsorptive and maldigestive diarrhea:\nThe first is due to impaired nutrient absorption, and the second is due to impaired digestive function.\nCeliac disease\nis one example.\nChronic infections:\nA history of travel or\nantibiotic\nuse can be clues in chronic diarrhea. Various bacteria and parasites can also be the cause.\nDrug-induced diarrhea:\nLaxatives and other drugs, including antibiotics, can trigger diarrhea.\nEndocrine-related causes:\nSometimes, hormonal factors cause diarrhea. This is the case in\nAddison’s disease\nand carcinoid tumors.\nCancer-related causes:\nNeoplastic diarrhea is associated with a number of gut cancers.\nMild cases of acute diarrhea may resolve without treatment. For persistent or chronic diarrhea, a doctor will treat any underlying causes in addition to the symptoms of diarrhea.\nThe sections below will discuss some possible treatment options for getting rid of diarrhea in more detail.\nRehydration\nReplacing the fluids, salts, and sugars lost during diarrhea is vital for all cases. However, children and older people are at\ngreater\nrisk\nof\ndehydration\n.\nOral rehydration solution or salts (ORS) can be particularly effective in dehydration recovery. ORS refers to water that contains salt and glucose. The small intestine absorbs the solution to replace the water and electrolytes lost in the stool. In developing countries, ORS costs just a few cents.\nAntidiarrheal medication\nOver-the-counter antidiarrheal medications are also available. These include\nloperamide (Imodium)\nand bismuth subsalicylate (Pepto-Bismol).\nImodium is an antimotility drug that reduces stool passage. Pepto-Bismol reduces diarrheal stool output in adults and children. It can also prevent traveler’s diarrhea.\nAntibiotics\nAntibiotics can only treat diarrhea due to bacterial infections. If the cause is a certain medication, switching to another drug might help.\nAlways talk with a doctor before switching medications.\nDiet\nThe following diet tips may help with diarrhea:\nsipping on clear liquids, such as electrolyte drinks, water, or fruit juice without added sugar\nafter each loose stool, replacing lost fluids with at least 1 cup of liquid\ndoing most of the drinking between, not during, meals\nconsuming high potassium foods and liquids, such as diluted fruit juices, potatoes without the skin, and\nbananas\nconsuming high sodium foods and liquids, such as broths, soups, sports drinks, and salted crackers\neating foods high in soluble fiber, such as banana, oatmeal, and rice, as these help thicken the stool\nlimiting foods that may make diarrhea worse, such as creamy, fried, high dairy, and sugary foods\nFoods and beverages that might make diarrhea worse include:\nsugar-free gum, mints, sweet cherries, and prunes\ncaffeinated drinks and medications\nfructose in high amounts, from fruit juices, grapes, honey, dates, nuts, figs, soft drinks, and prunes\nlactose in dairy products\nmagnesium\nolestra (Olean), which is a fat substitute\nanything that contains artificial sweeteners\nDiarrhea refers to watery stools, which may be accompanied by other symptoms. These include:\nstomach pain\nabdominal cramps\nbloating\nweight loss\nfever\nbody aches\nchills\nDiarrhea is also a symptom of other conditions, some of which can be serious. Other possible symptoms are:\nblood or\npus\nin the stool\npersistent vomiting\ndehydration\nIf any of these accompany diarrhea, or if the diarrhea is chronic, it may indicate a more serious illness.\nTwo potentially serious\ncomplications\nof diarrhea are dehydration (in cases of severe and frequent diarrhea) and\nmalabsorption\n(in cases of chronic diarrhea).\nDiarrhea can also indicate a wide range of underlying chronic conditions. Diagnosis and treatment can help prevent further problems.\nWhen diagnosing the cause of diarrhea, a doctor will ask about the person’s symptoms and:\nany current medications they take\ntheir past medical history\ntheir family history\ntheir travel history\nany other medical conditions they have\nThey will also ask:\nwhen the diarrhea started\nhow frequent the stools are\nif blood is present in the stool\nif the person has been vomiting\nwhether the stools are watery or contain mucus or pus\nhow much stool there is\nThey will also look for signs of dehydration. Severe dehydration can be fatal if the person does not receive rehydration therapy immediately.\nTests for diarrhea\nMost cases of diarrhea resolve without treatment, and a doctor will often be able to diagnose the problem without the use of tests.\nHowever, in more severe cases, a stool test may be necessary — especially if the symptoms persist for longer than a week.\nThe doctor may also recommend further tests if the person has:\nsigns of fever or dehydration\nstools with blood or pus\nsevere pain\nlow blood pressure\na weakened immune system\nrecently traveled\nrecently received antibiotics or been in the hospital\ndiarrhea persisting for longer than 1 week\nFurther tests\nIf a person has chronic or persistent diarrhea, the doctor will order tests according to the suspected cause.\nThese may include:\nA full blood count:\nAnemia may suggest malnutrition, bleeding ulcerations, or IBD.\nLiver function tests:\nThese will include testing albumin levels.\nTests for malabsorption:\nThese will check the absorption of\ncalcium\n,\nvitamin B-12\n, and\nfolate\n. They will also assess iron status and thyroid function.\nErythrocyte sedimentation rate and C-reactive protein:\nRaised levels may indicate IBD.\nTests for antibodies:\nThese may detect celiac disease.\nStool tests:\nDoctors can identify parasites, bacteria, and a few viruses in stool cultures. Stool tests can also reveal microscopic blood, white blood cells, and other clues for diagnosis.\nIn most cases, diarrhea isn’t something to be concerned about and will resolve itself without medical treatment. However, it is important to seek medical help when there is:\npersistent vomiting\npersistent diarrhea\ndehydration\nsignificant weight loss\npus in the stool\nblood in the stool, which may turn the stool black if it is coming from higher up in the gastrointestinal tract\nAnyone who experiences diarrhea after surgery, after spending time in the hospital, or after using antibiotics should seek medical attention.\nAdults who lose sleep due to diarrhea should also seek medical care as soon as possible, as this is usually a sign of more serious causes.\nIf a person has diarrhea and it lasts for more than\n7 days\n, they should consult a doctor urgently.\nAdditionally, caregivers should take infants to see a doctor as soon as possible if they have had\nmore than five bouts\nof diarrhea or vomited more than twice within 24 hours.\nThe following can help prevent diarrhea:\ndrinking clean and safe water only\nhaving good sanitation systems, such as wastewater and sewage\nhaving good hygiene practices, such as regularly washing the hands with soap, especially before preparing food and eating and after using the bathroom\neducating oneself on the spread of infection\nThere is evidence to suggest that interventions from public health bodies to promote hand-washing can reduce diarrhea rates by about\none-third\n.\nIn developing countries, however, the prevention of diarrhea may be more challenging due to dirty water and poor sanitation.\nDiarrhea is a common problem with many potential causes.\nIn most cases, a range of home remedies and medical treatments can help. However, a person should see their doctor if they are concerned about diarrhea or other symptoms.","attrs_markdown":"- Health Conditions\n  Health Conditions\n  \n  - [Alzheimer's & Dementia](https:\/\/www.medicalnewstoday.com\/alzheimers-and-dementia)\n  -

However, it is important to seek medical help when there is:\n\n- persistent vomiting\n- persistent diarrhea\n- dehydration\n- significant weight loss\n- pus in the stool\n- blood in the stool, which may turn the stool black if it is coming from higher up in the gastrointestinal tract\n\nAnyone who experiences diarrhea after surgery, after spending time in the hospital, or after using antibiotics should seek medical attention.\n\nAdults who lose sleep due to diarrhea should also seek medical care as soon as possible, as this is usually a sign of more serious causes.\n\n## [How long is too long for diarrhea?]()\nIf a person has diarrhea and it lasts for more than [7 days](https:\/\/www.nhsinform.scot\/illnesses-and-conditions\/stomach-liver-and-gastrointestinal-tract\/diarrhoea\/), they should consult a doctor urgently.\n\nAdditionally, caregivers should take infants to see a doctor as soon as possible if they have had [more than five bouts](https:\/\/www.nct.org.uk\/baby-toddler\/your-babys-health\/what-watch-out-for\/diarrhoea-and-vomiting-babies) of diarrhea or vomited more than twice within 24 hours.\n\n## [Prevention]()\nThe following can help prevent diarrhea:\n\n- drinking clean and safe water only\n- having good sanitation systems, such as wastewater and sewage\n- having good hygiene practices, such as regularly washing the hands with soap, especially before preparing food and eating and after using the bathroom\n- educating oneself on the spread of infection\n\nThere is evidence to suggest that interventions from public health bodies to promote hand-washing can reduce diarrhea rates by about [one-third](https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4563982\/).\n\nIn developing countries, however, the prevention of diarrhea may be more challenging due to dirty water and poor sanitation.\n\n## [Summary]()\nDiarrhea is a common problem with many potential causes.\n\nIn most cases, a range of home remedies and medical treatments can help. However, a person should see their doctor if they are concerned about diarrhea or other symptoms.\n\n- [Irritable Bowel Syndrome](https:\/\/www.medicalnewstoday.com\/categories\/irritable-bowel-syndrome)\n- [GastroIntestinal \/ Gastroenterology](https:\/\/www.medicalnewstoday.com\/categories\/gastrointestinal)\n- [Infectious Diseases \/ Bacteria \/ Viruses](https:\/\/www.medicalnewstoday.com\/categories\/infectious_diseases)\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.

Common causes include viruses, bacteria, and parasites.\n\nDiarrhea is characterized by loose or watery stools. Most cases of diarrhea are due to bacteria, viruses, or parasites. Digestive disorders can also cause chronic diarrhea.\n\nThis article looks at the causes and treatments of diarrhea. It also looks at symptoms, diagnosis, prevention, and when to see a doctor.\n\nMany cases of diarrhea are due to an infection or disruption of the gastrointestinal tract. [Common causes](https:\/\/www.niddk.nih.gov\/health-information\/digestive-diseases\/diarrhea\/symptoms-causes) of acute diarrhea include:\n\n- food poisoning\n- viral gastroenteritis\n- medicine side effects\n\nChronic diarrhea\n\nConditions such as [irritable bowel syndrome (IBS)](https:\/\/www.medicalnewstoday.com\/articles\/37063.php) are a common causes of “functional” chronic diarrhea. This means that although all the digestive organs appear normal, they are not functioning as they ideally should.\n\nSome other major causes of chronic diarrhea include:\n\n- **Microscopic colitis:** This is a persistent type of diarrhea that usually affects older adults. It develops due to inflammation and occurs often during the night.\n- **Malabsorptive and maldigestive diarrhea:** The first is due to impaired nutrient absorption, and the second is due to impaired digestive function. [Celiac disease](https:\/\/www.medicalnewstoday.com\/articles\/38085.php \"All about celiac disease\") is one example.\n- **Chronic infections:** A history of travel or [antibiotic](https:\/\/www.medicalnewstoday.com\/articles\/10278.php \"What to know about antibiotics\") use can be clues in chronic diarrhea. Various bacteria and parasites can also be the cause.\n- **Drug-induced diarrhea:** Laxatives and other drugs, including antibiotics, can trigger diarrhea.\n- **Endocrine-related causes:** Sometimes, hormonal factors cause diarrhea. This is the case in [Addison’s disease](https:\/\/www.medicalnewstoday.com\/articles\/186236) and carcinoid tumors.\n- **Cancer-related causes:** Neoplastic diarrhea is associated with a number of gut cancers.\n\nMild cases of acute diarrhea may resolve without treatment. For persistent or chronic diarrhea, a doctor will treat any underlying causes in addition to the symptoms of diarrhea.\n\nThe sections below will discuss some possible treatment options for getting rid of diarrhea in more detail.\n\nRehydration\n\nReplacing the fluids, salts, and sugars lost during diarrhea is vital for all cases. However, children and older people are at [greater](https:\/\/www.nhs.uk\/conditions\/dehydration\/) [risk](https:\/\/www.nhs.uk\/conditions\/dehydration\/) of [dehydration](https:\/\/www.medicalnewstoday.com\/articles\/153363.php).\n\nOral rehydration solution or salts (ORS) can be particularly effective in dehydration recovery. ORS refers to water that contains salt and glucose. The small intestine absorbs the solution to replace the water and electrolytes lost in the stool. In developing countries, ORS costs just a few cents.\n\nAntidiarrheal medication\n\nOver-the-counter antidiarrheal medications are also available. These include [loperamide (Imodium)](https:\/\/www.medicalnewstoday.com\/articles\/imodium) and bismuth subsalicylate (Pepto-Bismol).\n\nImodium is an antimotility drug that reduces stool passage. Pepto-Bismol reduces diarrheal stool output in adults and children. It can also prevent traveler’s diarrhea.\n\nAntibiotics\n\nAntibiotics can only treat diarrhea due to bacterial infections. If the cause is a certain medication, switching to another drug might help.\n\nAlways talk with a doctor before switching medications.\n\nDiet\n\nThe following diet tips may help with diarrhea:\n\n- sipping on clear liquids, such as electrolyte drinks, water, or fruit juice without added sugar\n- after each loose stool, replacing lost fluids with at least 1 cup of liquid\n- doing most of the drinking between, not during, meals\n- consuming high potassium foods and liquids, such as diluted fruit juices, potatoes without the skin, and [bananas](https:\/\/www.medicalnewstoday.com\/articles\/271157.php \"Benefits and health risks of bananas\")\n- consuming high sodium foods and liquids, such as broths, soups, sports drinks, and salted crackers\n- eating foods high in soluble fiber, such as banana, oatmeal, and rice, as these help thicken the stool\n- limiting foods that may make diarrhea worse, such as creamy, fried, high dairy, and sugary foods\n\nFoods and beverages that might make diarrhea worse include:\n\n- sugar-free gum, mints, sweet cherries, and prunes\n- caffeinated drinks and medications\n- fructose in high amounts, from fruit juices, grapes, honey, dates, nuts, figs, soft drinks, and prunes\n- lactose in dairy products\n- [magnesium](https:\/\/www.medicalnewstoday.com\/articles\/286839.php \"Why do we need magnesium?\")\n- olestra (Olean), which is a fat substitute\n- anything that contains artificial sweeteners\n\nDiarrhea refers to watery stools, which may be accompanied by other symptoms. These include:\n\n- stomach pain\n- abdominal cramps\n- bloating\n- weight loss\n- [fever](https:\/\/www.medicalnewstoday.com\/articles\/168266.php \"Fever: What you need to know\")\n- body aches\n- chills\n\nDiarrhea is also a symptom of other conditions, some of which can be serious. Other possible symptoms are:\n\n- blood or [pus](https:\/\/www.medicalnewstoday.com\/articles\/249182.php \"What is pus?\") in the stool\n- persistent vomiting\n- dehydration\n\nIf any of these accompany diarrhea, or if the diarrhea is chronic, it may indicate a more serious illness.\n\nTwo potentially serious [complications](https:\/\/www.msdmanuals.com\/professional\/gastrointestinal-disorders\/symptoms-of-gastrointestinal-disorders\/diarrhea#Etiology_v889020) of diarrhea are dehydration (in cases of severe and frequent diarrhea) and [malabsorption](https:\/\/www.medicalnewstoday.com\/articles\/322467) (in cases of chronic diarrhea).\n\nDiarrhea can also indicate a wide range of underlying chronic conditions. Diagnosis and treatment can help prevent further problems.\n\nWhen diagnosing the cause of diarrhea, a doctor will ask about the person’s symptoms and:\n\n- any current medications they take\n- their past medical history\n- their family history\n- their travel history\n- any other medical conditions they have\n\nThey will also ask:\n\n- when the diarrhea started\n- how frequent the stools are\n- if blood is present in the stool\n- if the person has been vomiting\n- whether the stools are watery or contain mucus or pus\n- how much stool there is\n\nThey will also look for signs of dehydration. Severe dehydration can be fatal if the person does not receive rehydration therapy immediately.\n\nTests for diarrhea\n\nMost cases of diarrhea resolve without treatment, and a doctor will often be able to diagnose the problem without the use of tests.\n\nHowever, in more severe cases, a stool test may be necessary — especially if the symptoms persist for longer than a week.\n\nThe doctor may also recommend further tests if the person has:\n\n- signs of fever or dehydration\n- stools with blood or pus\n- severe pain\n- [low blood pressure](https:\/\/www.medicalnewstoday.com\/articles\/159609)\n- a weakened immune system\n- recently traveled\n- recently received antibiotics or been in the hospital\n- diarrhea persisting for longer than 1 week\n\nFurther tests\n\nIf a person has chronic or persistent diarrhea, the doctor will order tests according to the suspected cause.\n\nThese may include:\n\n- **A full blood count:** Anemia may suggest malnutrition, bleeding ulcerations, or IBD.\n- **Liver function tests:** These will include testing albumin levels.\n- **Tests for malabsorption:** These will check the absorption of [calcium](https:\/\/www.medicalnewstoday.com\/articles\/248958.php \"Calcium: Health benefits, foods, and deficiency\"), [vitamin B-12](https:\/\/www.medicalnewstoday.com\/articles\/219822), and [folate](https:\/\/www.medicalnewstoday.com\/articles\/287677.php \"Why is folate good for you?\"). They will also assess iron status and thyroid function.\n- **Erythrocyte sedimentation rate and C-reactive protein:** Raised levels may indicate IBD.\n- **Tests for antibodies:** These may detect celiac disease.\n- **Stool tests:** Doctors can identify parasites, bacteria, and a few viruses in stool cultures.

Other possible symptoms are: blood or pus in the stool persistent vomiting dehydration If any of these accompany diarrhea, or if the diarrhea is chronic, it may indicate a more serious illness. Two potentially serious complications of diarrhea are dehydration (in cases of severe and frequent diarrhea) and malabsorption (in cases of chronic diarrhea). Diarrhea can also indicate a wide range of underlying chronic conditions. Diagnosis and treatment can help prevent further problems. When diagnosing the cause of diarrhea, a doctor will ask about the person’s symptoms and: any current medications they take their past medical history their family history their travel history any other medical conditions they have They will also ask: when the diarrhea started how frequent the stools are if blood is present in the stool if the person has been vomiting whether the stools are watery or contain mucus or pus how much stool there is They will also look for signs of dehydration. Severe dehydration can be fatal if the person does not receive rehydration therapy immediately. Tests for diarrhea Most cases of diarrhea resolve without treatment, and a doctor will often be able to diagnose the problem without the use of tests. However, in more severe cases, a stool test may be necessary — especially if the symptoms persist for longer than a week. The doctor may also recommend further tests if the person has: signs of fever or dehydration stools with blood or pus severe pain low blood pressure a weakened immune system recently traveled recently received antibiotics or been in the hospital diarrhea persisting for longer than 1 week Further tests If a person has chronic or persistent diarrhea, the doctor will order tests according to the suspected cause. These may include: A full blood count: Anemia may suggest malnutrition, bleeding ulcerations, or IBD. Liver function tests: These will include testing albumin levels. Tests for malabsorption: These will check the absorption of calcium , vitamin B-12 , and folate . They will also assess iron status and thyroid function. Erythrocyte sedimentation rate and C-reactive protein: Raised levels may indicate IBD. Tests for antibodies: These may detect celiac disease. Stool tests: Doctors can identify parasites, bacteria, and a few viruses in stool cultures. Stool tests can also reveal microscopic blood, white blood cells, and other clues for diagnosis. In most cases, diarrhea isn’t something to be concerned about and will resolve itself without medical treatment. However, it is important to seek medical help when there is: persistent vomiting persistent diarrhea dehydration significant weight loss pus in the stool blood in the stool, which may turn the stool black if it is coming from higher up in the gastrointestinal tract Anyone who experiences diarrhea after surgery, after spending time in the hospital, or after using antibiotics should seek medical attention. Adults who lose sleep due to diarrhea should also seek medical care as soon as possible, as this is usually a sign of more serious causes. If a person has diarrhea and it lasts for more than 7 days , they should consult a doctor urgently. Additionally, caregivers should take infants to see a doctor as soon as possible if they have had more than five bouts of diarrhea or vomited more than twice within 24 hours. The following can help prevent diarrhea: drinking clean and safe water only having good sanitation systems, such as wastewater and sewage having good hygiene practices, such as regularly washing the hands with soap, especially before preparing food and eating and after using the bathroom educating oneself on the spread of infection There is evidence to suggest that interventions from public health bodies to promote hand-washing can reduce diarrhea rates by about one-third . In developing countries, however, the prevention of diarrhea may be more challenging due to dirty water and poor sanitation. Diarrhea is a common problem with many potential causes. In most cases, a range of home remedies and medical treatments can help. However, a person should see their doctor if they are concerned about diarrhea or other symptoms.

[Prevention](https://www.medicalnewstoday.com/articles/158634#prevention) - [Summary](https://www.medicalnewstoday.com/articles/158634#summary) Diarrhea can range from a mild, temporary condition to a potentially life threatening one. Common causes include viruses, bacteria, and parasites. Diarrhea is characterized by loose or watery stools. Most cases of diarrhea are due to bacteria, viruses, or parasites. Digestive disorders can also cause chronic diarrhea. This article looks at the causes and treatments of diarrhea. It also looks at symptoms, diagnosis, prevention, and when to see a doctor. ## [What are the main causes of diarrhea?]() ![An empty toilet paper roll](https://media.post.rvohealth.io/wp-content/uploads/sites/3/2025/03/empty-toilet-paper-roll-1296x728-header-1024x575.jpg) [Share on Pinterest](https://www.pinterest.com/pin/create/button/?url=https%3A%2F%2Fwww.medicalnewstoday.com%2Farticles%2F158634&media=https%3A%2F%2Fmedia.post.rvohealth.io%2Fwp-content%2Fuploads%2Fsites%2F3%2F2025%2F03%2Fempty-toilet-paper-roll-1296x728-header-1024x575.jpg&description=Diarrhea%3A%20Causes%2C%20treatment%2C%20and%20symptoms "Share on Pinterest") Juan Moyano/Stocksy Many cases of diarrhea are due to an infection or disruption of the gastrointestinal tract. [Common causes](https://www.niddk.nih.gov/health-information/digestive-diseases/diarrhea/symptoms-causes) of acute diarrhea include: - food poisoning - viral gastroenteritis - medicine side effects ### Chronic diarrhea Conditions such as [irritable bowel syndrome (IBS)](https://www.medicalnewstoday.com/articles/37063.php) are a common causes of “functional” chronic diarrhea. This means that although all the digestive organs appear normal, they are not functioning as they ideally should. Some other major causes of chronic diarrhea include: - Microscopic colitis: This is a persistent type of diarrhea that usually affects older adults. It develops due to inflammation and occurs often during the night. - Malabsorptive and maldigestive diarrhea: The first is due to impaired nutrient absorption, and the second is due to impaired digestive function. [Celiac disease](https://www.medicalnewstoday.com/articles/38085.php "All about celiac disease") is one example. - Chronic infections: A history of travel or [antibiotic](https://www.medicalnewstoday.com/articles/10278.php "What to know about antibiotics") use can be clues in chronic diarrhea. Various bacteria and parasites can also be the cause. - Drug-induced diarrhea: Laxatives and other drugs, including antibiotics, can trigger diarrhea. - Endocrine-related causes: Sometimes, hormonal factors cause diarrhea. This is the case in [Addison’s disease](https://www.medicalnewstoday.com/articles/186236) and carcinoid tumors. - Cancer-related causes: Neoplastic diarrhea is associated with a number of gut cancers. ## [Quiz]() ## [How can a person treat diarrhea?]() Mild cases of acute diarrhea may resolve without treatment. For persistent or chronic diarrhea, a doctor will treat any underlying causes in addition to the symptoms of diarrhea. The sections below will discuss some possible treatment options for getting rid of diarrhea in more detail. ### Rehydration Replacing the fluids, salts, and sugars lost during diarrhea is vital for all cases. However, children and older people are at [greater](https://www.nhs.uk/conditions/dehydration/) [risk](https://www.nhs.uk/conditions/dehydration/) of [dehydration](https://www.medicalnewstoday.com/articles/153363.php). Oral rehydration solution or salts (ORS) can be particularly effective in dehydration recovery. ORS refers to water that contains salt and glucose. The small intestine absorbs the solution to replace the water and electrolytes lost in the stool. In developing countries, ORS costs just a few cents. ### Antidiarrheal medication Over-the-counter antidiarrheal medications are also available. These include [loperamide (Imodium)](https://www.medicalnewstoday.com/articles/imodium) and bismuth subsalicylate (Pepto-Bismol). Imodium is an antimotility drug that reduces stool passage. Pepto-Bismol reduces diarrheal stool output in adults and children. It can also prevent traveler’s diarrhea. ### Antibiotics Antibiotics can only treat diarrhea due to bacterial infections. If the cause is a certain medication, switching to another drug might help. Always talk with a doctor before switching medications. ### Diet The following diet tips may help with diarrhea: - sipping on clear liquids, such as electrolyte drinks, water, or fruit juice without added sugar - after each loose stool, replacing lost fluids with at least 1 cup of liquid - doing most of the drinking between, not during, meals - consuming high potassium foods and liquids, such as diluted fruit juices, potatoes without the skin, and [bananas](https://www.medicalnewstoday.com/articles/271157.php "Benefits and health risks of bananas") - consuming high sodium foods and liquids, such as broths, soups, sports drinks, and salted crackers - eating foods high in soluble fiber, such as banana, oatmeal, and rice, as these help thicken the stool - limiting foods that may make diarrhea worse, such as creamy, fried, high dairy, and sugary foods Foods and beverages that might make diarrhea worse include: - sugar-free gum, mints, sweet cherries, and prunes - caffeinated drinks and medications - fructose in high amounts, from fruit juices, grapes, honey, dates, nuts, figs, soft drinks, and prunes - lactose in dairy products - [magnesium](https://www.medicalnewstoday.com/articles/286839.php "Why do we need magnesium?") - olestra (Olean), which is a fat substitute - anything that contains artificial sweeteners [Learn more about foods to eat with diarrhea here](https://www.medicalnewstoday.com/articles/320124). ## [Symptoms]() Diarrhea refers to watery stools, which may be accompanied by other symptoms. These include: - stomach pain - abdominal cramps - bloating - weight loss - [fever](https://www.medicalnewstoday.com/articles/168266.php "Fever: What you need to know") - body aches - chills Diarrhea is also a symptom of other conditions, some of which can be serious. Other possible symptoms are: - blood or [pus](https://www.medicalnewstoday.com/articles/249182.php "What is pus?") in the stool - persistent vomiting - dehydration If any of these accompany diarrhea, or if the diarrhea is chronic, it may indicate a more serious illness. ## [Complications]() Two potentially serious [complications](https://www.msdmanuals.com/professional/gastrointestinal-disorders/symptoms-of-gastrointestinal-disorders/diarrhea#Etiology_v889020) of diarrhea are dehydration (in cases of severe and frequent diarrhea) and [malabsorption](https://www.medicalnewstoday.com/articles/322467) (in cases of chronic diarrhea). Diarrhea can also indicate a wide range of underlying chronic conditions. Diagnosis and treatment can help prevent further problems. ## [Tests and diagnosis]() When diagnosing the cause of diarrhea, a doctor will ask about the person’s symptoms and: - any current medications they take - their past medical history - their family history - their travel history - any other medical conditions they have They will also ask: - when the diarrhea started - how frequent the stools are - if blood is present in the stool - if the person has been vomiting - whether the stools are watery or contain mucus or pus - how much stool there is They will also look for signs of dehydration. Severe dehydration can be fatal if the person does not receive rehydration therapy immediately. ### Tests for diarrhea Most cases of diarrhea resolve without treatment, and a doctor will often be able to diagnose the problem without the use of tests. However, in more severe cases, a stool test may be necessary — especially if the symptoms persist for longer than a week. The doctor may also recommend further tests if the person has: - signs of fever or dehydration - stools with blood or pus - severe pain - [low blood pressure](https://www.medicalnewstoday.com/articles/159609) - a weakened immune system - recently traveled - recently received antibiotics or been in the hospital - diarrhea persisting for longer than 1 week ### Further tests If a person has chronic or persistent diarrhea, the doctor will order tests according to the suspected cause. These may include: - A full blood count: Anemia may suggest malnutrition, bleeding ulcerations, or IBD. - Liver function tests: These will include testing albumin levels. - Tests for malabsorption: These will check the absorption of [calcium](https://www.medicalnewstoday.com/articles/248958.php "Calcium: Health benefits, foods, and deficiency"), [vitamin B-12](https://www.medicalnewstoday.com/articles/219822), and [folate](https://www.medicalnewstoday.com/articles/287677.php "Why is folate good for you?"). They will also assess iron status and thyroid function. - Erythrocyte sedimentation rate and C-reactive protein: Raised levels may indicate IBD. - Tests for antibodies: These may detect celiac disease. - Stool tests: Doctors can identify parasites, bacteria, and a few viruses in stool cultures. Stool tests can also reveal microscopic blood, white blood cells, and other clues for diagnosis. ## [When should a person be concerned about diarrhea?]() In most cases, diarrhea isn’t something to be concerned about and will resolve itself without medical treatment. However, it is important to seek medical help when there is: - persistent vomiting - persistent diarrhea - dehydration - significant weight loss - pus in the stool - blood in the stool, which may turn the stool black if it is coming from higher up in the gastrointestinal tract Anyone who experiences diarrhea after surgery, after spending time in the hospital, or after using antibiotics should seek medical attention. Adults who lose sleep due to diarrhea should also seek medical care as soon as possible, as this is usually a sign of more serious causes. ## [How long is too long for diarrhea?]() If a person has diarrhea and it lasts for more than [7 days](https://www.nhsinform.scot/illnesses-and-conditions/stomach-liver-and-gastrointestinal-tract/diarrhoea/), they should consult a doctor urgently. Additionally, caregivers should take infants to see a doctor as soon as possible if they have had [more than five bouts](https://www.nct.org.uk/baby-toddler/your-babys-health/what-watch-out-for/diarrhoea-and-vomiting-babies) of diarrhea or vomited more than twice within 24 hours. ## [Prevention]() The following can help prevent diarrhea: - drinking clean and safe water only - having good sanitation systems, such as wastewater and sewage - having good hygiene practices, such as regularly washing the hands with soap, especially before preparing food and eating and after using the bathroom - educating oneself on the spread of infection There is evidence to suggest that interventions from public health bodies to promote hand-washing can reduce diarrhea rates by about [one-third](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4563982/). In developing countries, however, the prevention of diarrhea may be more challenging due to dirty water and poor sanitation. ## [Summary]() Diarrhea is a common problem with many potential causes. In most cases, a range of home remedies and medical treatments can help. However, a person should see their doctor if they are concerned about diarrhea or other symptoms. - [Irritable Bowel Syndrome](https://www.medicalnewstoday.com/categories/irritable-bowel-syndrome) - [GastroIntestinal / Gastroenterology](https://www.medicalnewstoday.com/categories/gastrointestinal) - [Infectious Diseases / Bacteria / Viruses](https://www.medicalnewstoday.com/categories/infectious_diseases) ### How we reviewed this article: Sources Medical News Today has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical journals and associations.

Two potentially serious [complications](https://www.msdmanuals.com/professional/gastrointestinal-disorders/symptoms-of-gastrointestinal-disorders/diarrhea#Etiology_v889020) of diarrhea are dehydration (in cases of severe and frequent diarrhea) and [malabsorption](https://www.medicalnewstoday.com/articles/322467) (in cases of chronic diarrhea). Diarrhea can also indicate a wide range of underlying chronic conditions. Diagnosis and treatment can help prevent further problems. When diagnosing the cause of diarrhea, a doctor will ask about the person’s symptoms and: - any current medications they take - their past medical history - their family history - their travel history - any other medical conditions they have They will also ask: - when the diarrhea started - how frequent the stools are - if blood is present in the stool - if the person has been vomiting - whether the stools are watery or contain mucus or pus - how much stool there is They will also look for signs of dehydration. Severe dehydration can be fatal if the person does not receive rehydration therapy immediately. Tests for diarrhea Most cases of diarrhea resolve without treatment, and a doctor will often be able to diagnose the problem without the use of tests. However, in more severe cases, a stool test may be necessary — especially if the symptoms persist for longer than a week. The doctor may also recommend further tests if the person has: - signs of fever or dehydration - stools with blood or pus - severe pain - [low blood pressure](https://www.medicalnewstoday.com/articles/159609) - a weakened immune system - recently traveled - recently received antibiotics or been in the hospital - diarrhea persisting for longer than 1 week Further tests If a person has chronic or persistent diarrhea, the doctor will order tests according to the suspected cause. These may include: - A full blood count: Anemia may suggest malnutrition, bleeding ulcerations, or IBD. - Liver function tests: These will include testing albumin levels. - Tests for malabsorption: These will check the absorption of [calcium](https://www.medicalnewstoday.com/articles/248958.php "Calcium: Health benefits, foods, and deficiency"), [vitamin B-12](https://www.medicalnewstoday.com/articles/219822), and [folate](https://www.medicalnewstoday.com/articles/287677.php "Why is folate good for you?"). They will also assess iron status and thyroid function. - Erythrocyte sedimentation rate and C-reactive protein: Raised levels may indicate IBD. - Tests for antibodies: These may detect celiac disease. - Stool tests: Doctors can identify parasites, bacteria, and a few viruses in stool cultures. Stool tests can also reveal microscopic blood, white blood cells, and other clues for diagnosis. In most cases, diarrhea isn’t something to be concerned about and will resolve itself without medical treatment. However, it is important to seek medical help when there is: - persistent vomiting - persistent diarrhea - dehydration - significant weight loss - pus in the stool - blood in the stool, which may turn the stool black if it is coming from higher up in the gastrointestinal tract Anyone who experiences diarrhea after surgery, after spending time in the hospital, or after using antibiotics should seek medical attention. Adults who lose sleep due to diarrhea should also seek medical care as soon as possible, as this is usually a sign of more serious causes. If a person has diarrhea and it lasts for more than [7 days](https://www.nhsinform.scot/illnesses-and-conditions/stomach-liver-and-gastrointestinal-tract/diarrhoea/), they should consult a doctor urgently. Additionally, caregivers should take infants to see a doctor as soon as possible if they have had [more than five bouts](https://www.nct.org.uk/baby-toddler/your-babys-health/what-watch-out-for/diarrhoea-and-vomiting-babies) of diarrhea or vomited more than twice within 24 hours. The following can help prevent diarrhea: - drinking clean and safe water only - having good sanitation systems, such as wastewater and sewage - having good hygiene practices, such as regularly washing the hands with soap, especially before preparing food and eating and after using the bathroom - educating oneself on the spread of infection There is evidence to suggest that interventions from public health bodies to promote hand-washing can reduce diarrhea rates by about [one-third](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4563982/). In developing countries, however, the prevention of diarrhea may be more challenging due to dirty water and poor sanitation. Diarrhea is a common problem with many potential causes. In most cases, a range of home remedies and medical treatments can help. However, a person should see their doctor if they are concerned about diarrhea or other symptoms.
