All forms can be quite debilitating and affect 6 million people in the U.S.\nNot being able to\ndetect bad smells\ncan be quite troublesome, such as a parent not being able to detect the smell of a dirty diaper, or even dangerous, such as not smelling smoke or natural gas fumes.\nThe Relationship Between Loss of Smell and Loss of Taste\nYou’d be surprised how your sense of smell is directly connected to your sense of taste. 80% of taste disorders (ageusia) are from an impaired sense of smell.\nWhen you eat, special chemical substances called aromatics are released and travel from the back of your throat up to your nose. These aromatics stimulate your nose and, coupled with your taste buds, determine how you perceive food.\nCauses of Loss of Smell and Taste\nOlfactory disorders have many causes, and a specialist such as an ear, nose, and throat (ENT) doctor is typically necessary to sort out the root cause. As a rule, if you have lost your sense of smell for more than two weeks, you should seek a physician to determine the cause.\nNasal Obstruction\nThe most common cause for loss of smell and taste is simply\nnasal obstruction\n, such as from\ncongestion\ndue to\na cold or bad allergies\n. Long-standing nasal obstruction from something like\nnasal polyps\nor severe nasal septal deflections can also be a cause of obstruction.\nEither way, if your nose is blocked, you won’t be able to get those aromatic particles to reach the top of your nose to stimulate the nerves of olfaction.\nInfection\nThe second most common cause is damage from an infection, especially viruses. Viruses are known to damage all kinds of nerves (especially cranial nerves), including the nerves in the nose used for smell.\nAfter a viral infection, sense of smell typically returns within two weeks, although recovery can vary from weeks to months. Permanent damage to the nerves may also occur.\nCoronavirus\nThe coronavirus that has led to the COVID-19 pandemic has caused an increase in patients losing their sense of smell and taste. Like any virus, the coronavirus attaches to the nasal receptors (specifically the ACE2 receptor) and causes damage.\nIn our clinic, we’ve found that recovery is often extended to several months post-COVID and is often associated with a temporary phase of parosmia, where your sense of smell or taste changes (oftentimes for the worse).\nAdditional Causes\nLess common causes of olfactory disorders include head trauma (concussions), various nasal and brain masses and tumors, neurodegenerative disorders (dementia), as well as toxin and medicine side effects. In some patients, the cause may simply be unknown.\n[Related:\nWhat Can Cause Loss of Smell?\n]\nTreatments for Loss of Smell & Taste\nIn\nDr. Pasha’s clinic\n, several steps are required in the work-up of olfactory issues to formulate a treatment plan, including\nnasal endoscopy\n(a painless microscopic evaluation of the nose),\nallergy testing\n, and a CT scan (X-ray). All tests can be performed in the office.\nTreatment for loss of smell and taste depends on the cause. For example, if you have\nnasal polyps\n, then have them removed. If you have a viral infection, you may need to take medications to reduce the inflammation caused by the infection.\nFor those who have long-standing loss of smell, olfactory training (or smell training) may be beneficial. Dr. Pasha has his own olfactory training regimen that he may provide for you. The future of anosmia management is growing and includes stem cell research and even gene therapy for some congenital causes.\nLoss of smell can be frustrating for patients. The key is to spend the time necessary to identify the cause so you can focus your therapy.","attrs_markdown":"[Skip to main content](https:\/\/breathefreely.com\/education-library\/loss-of-smell-taste-anosmia\/anosmia-overview\/#ajax-content-wrap)\n\n[![Houston ENT Doctor](https:\/\/breathefreely.com\/wp-content\/uploads\/2021\/03\/No-Clearspace-2.png)![Houston ENT Doctor](https:\/\/breathefreely.com\/wp-content\/uploads\/2021\/03\/logo.png)![Houston ENT Doctor](https:\/\/breathefreely.com\/wp-content\/uploads\/2021\/03\/No-Clearspace-2.png)](https:\/\/breathefreely.com\/)\n\n[search](https:\/\/breathefreely.com\/education-library\/loss-of-smell-taste-anosmia\/anosmia-overview\/#searchbox)\n\n[*Menu*](https:\/\/breathefreely.com\/education-library\/loss-of-smell-taste-anosmia\/anosmia-overview\/#mobile-menu)\n\n- [Menu](https:\/\/breathefreely.com\/education-library\/loss-of-smell-taste-anosmia\/anosmia-overview\/)\n  - [Our Providers]()\n    - [Raza Pasha, MD](https:\/\/breathefreely.com\/about-us\/meet-dr-pasha\/)\n    - [Philip A.

All forms can be quite debilitating and affect 6 million people in the U.S.\n\nNot being able to [detect bad smells](https:\/\/breathefreely.com\/media\/faq-bad-smells\/) can be quite troublesome, such as a parent not being able to detect the smell of a dirty diaper, or even dangerous, such as not smelling smoke or natural gas fumes.\n\n## The Relationship Between Loss of Smell and Loss of Taste\nYou’d be surprised how your sense of smell is directly connected to your sense of taste. 80% of taste disorders (ageusia) are from an impaired sense of smell.\n\nWhen you eat, special chemical substances called aromatics are released and travel from the back of your throat up to your nose. These aromatics stimulate your nose and, coupled with your taste buds, determine how you perceive food.\n\n## Causes of Loss of Smell and Taste\nOlfactory disorders have many causes, and a specialist such as an ear, nose, and throat (ENT) doctor is typically necessary to sort out the root cause. As a rule, if you have lost your sense of smell for more than two weeks, you should seek a physician to determine the cause.\n\n### Nasal Obstruction\nThe most common cause for loss of smell and taste is simply [nasal obstruction](https:\/\/breathefreely.com\/education-library\/endoscopic-sinus-surgery\/), such as from [congestion](https:\/\/breathefreely.com\/6-foods-to-fight-nasal-congestion\/) due to [a cold or bad allergies](https:\/\/breathefreely.com\/cold-vs-allergies-how-to-spot-the-differences\/). Long-standing nasal obstruction from something like [nasal polyps](https:\/\/breathefreely.com\/education-library\/nasal-polyps\/) or severe nasal septal deflections can also be a cause of obstruction.\n\nEither way, if your nose is blocked, you won’t be able to get those aromatic particles to reach the top of your nose to stimulate the nerves of olfaction.\n\n### Infection\nThe second most common cause is damage from an infection, especially viruses. Viruses are known to damage all kinds of nerves (especially cranial nerves), including the nerves in the nose used for smell.\n\nAfter a viral infection, sense of smell typically returns within two weeks, although recovery can vary from weeks to months. Permanent damage to the nerves may also occur.\n\n### Coronavirus\nThe coronavirus that has led to the COVID-19 pandemic has caused an increase in patients losing their sense of smell and taste. Like any virus, the coronavirus attaches to the nasal receptors (specifically the ACE2 receptor) and causes damage.\n\nIn our clinic, we’ve found that recovery is often extended to several months post-COVID and is often associated with a temporary phase of parosmia, where your sense of smell or taste changes (oftentimes for the worse).\n\n### Additional Causes\nLess common causes of olfactory disorders include head trauma (concussions), various nasal and brain masses and tumors, neurodegenerative disorders (dementia), as well as toxin and medicine side effects. In some patients, the cause may simply be unknown.\n\n**\\[Related: [What Can Cause Loss of Smell?](https:\/\/breathefreely.com\/loss-of-smell\/)\\]**\n\n## Treatments for Loss of Smell & Taste\nIn [Dr. Pasha’s clinic](https:\/\/breathefreely.com\/), several steps are required in the work-up of olfactory issues to formulate a treatment plan, including [nasal endoscopy](https:\/\/breathefreely.com\/what-is-nasal-endoscopy\/) (a painless microscopic evaluation of the nose), [allergy testing](https:\/\/breathefreely.com\/education-library\/allergy-management\/), and a CT scan (X-ray). All tests can be performed in the office.\n\nTreatment for loss of smell and taste depends on the cause. For example, if you have [nasal polyps](https:\/\/breathefreely.com\/education-library\/nasal-polyps\/), then have them removed. If you have a viral infection, you may need to take medications to reduce the inflammation caused by the infection.\n\nFor those who have long-standing loss of smell, olfactory training (or smell training) may be beneficial. Dr. Pasha has his own olfactory training regimen that he may provide for you. The future of anosmia management is growing and includes stem cell research and even gene therapy for some congenital causes.\n\nLoss of smell can be frustrating for patients. The key is to spend the time necessary to identify the cause so you can focus your therapy.\n\n## Loss of Smell & Taste FAQs\n\n###### What Is Olfactory Training?\nOlfactory training is a method to restimulate the nose to recognize smell.\n\nA simple method is to gather four different major scents. Most common are lemon, rose, cloves, and eucalyptus, usually from essential oils. Place these scents under your nose twice a day. The goal is to try to reconnect the connection of smell with the brain. The method may take months, but there are no risks or high costs.\n\nDr. Pasha and his staff have their own olfactory training program that may be prescribed for you.\n\n###### Do Corticosteroids Work?\nCorticosteroids in the form of a nasal spray or medication by mouth have variable success rates. Depending on the potential cause of your loss of smell and taste, Dr. Pasha may prescribe a course to reduce the inflammatory damage that affects olfactory nerves.\n\n###### What About Surgery for Loss of Smell?\nThat depends. If the cause of your loss of smell is from the obstruction caused by [nasal polyps](https:\/\/breathefreely.com\/education-library\/nasal-polyps\/) or structural blockage, Dr. Pasha may suggest [a procedure](https:\/\/breathefreely.com\/education-library\/endoscopic-sinus-surgery\/) to open up your nasal passages.\n\n[![image of nose with light radiating from within](https:\/\/breathefreely.com\/wp-content\/uploads\/2021\/08\/nose-obstruction-1024x1024-1.jpg)](https:\/\/breathefreely.com\/loss-of-smell\/)\n\n#### What Can Cause Loss of Smell?\nHaving trouble smelling things around you is not normal and could be caused by several conditions. The complete or partial loss of smell is called anosmia and it can be temporary or permanent, depending on what caused it. Loss of smell is usually a symptom of another medical condition.\n\n[Read More](https:\/\/breathefreely.com\/loss-of-smell\/)\n\n[![woman smelling orange peel suspiciously](https:\/\/breathefreely.com\/wp-content\/uploads\/2021\/08\/Loss-of-Smell-What-Causes-It-and-Why-Its-a-Big-Deal.jpg)](https:\/\/breathefreely.com\/how-olfactory-training-can-help-you-regain-your-sense-of-smell\/)\n\n#### How Olfactory Training Can Help You Regain Your Sense Of Smell\nHas recovering from a viral infection left you without a sense of smell?

All forms can be quite debilitating and affect 6 million people in the U.S. Not being able to [detect bad smells](https://breathefreely.com/media/faq-bad-smells/) can be quite troublesome, such as a parent not being able to detect the smell of a dirty diaper, or even dangerous, such as not smelling smoke or natural gas fumes. ## The Relationship Between Loss of Smell and Loss of Taste You’d be surprised how your sense of smell is directly connected to your sense of taste. 80% of taste disorders (ageusia) are from an impaired sense of smell. When you eat, special chemical substances called aromatics are released and travel from the back of your throat up to your nose. These aromatics stimulate your nose and, coupled with your taste buds, determine how you perceive food. ## Causes of Loss of Smell and Taste Olfactory disorders have many causes, and a specialist such as an ear, nose, and throat (ENT) doctor is typically necessary to sort out the root cause. As a rule, if you have lost your sense of smell for more than two weeks, you should seek a physician to determine the cause. ### Nasal Obstruction The most common cause for loss of smell and taste is simply [nasal obstruction](https://breathefreely.com/education-library/endoscopic-sinus-surgery/), such as from [congestion](https://breathefreely.com/6-foods-to-fight-nasal-congestion/) due to [a cold or bad allergies](https://breathefreely.com/cold-vs-allergies-how-to-spot-the-differences/). Long-standing nasal obstruction from something like [nasal polyps](https://breathefreely.com/education-library/nasal-polyps/) or severe nasal septal deflections can also be a cause of obstruction. Either way, if your nose is blocked, you won’t be able to get those aromatic particles to reach the top of your nose to stimulate the nerves of olfaction. ### Infection The second most common cause is damage from an infection, especially viruses. Viruses are known to damage all kinds of nerves (especially cranial nerves), including the nerves in the nose used for smell. After a viral infection, sense of smell typically returns within two weeks, although recovery can vary from weeks to months. Permanent damage to the nerves may also occur. ### Coronavirus The coronavirus that has led to the COVID-19 pandemic has caused an increase in patients losing their sense of smell and taste. Like any virus, the coronavirus attaches to the nasal receptors (specifically the ACE2 receptor) and causes damage. In our clinic, we’ve found that recovery is often extended to several months post-COVID and is often associated with a temporary phase of parosmia, where your sense of smell or taste changes (oftentimes for the worse). ### Additional Causes Less common causes of olfactory disorders include head trauma (concussions), various nasal and brain masses and tumors, neurodegenerative disorders (dementia), as well as toxin and medicine side effects. In some patients, the cause may simply be unknown. \[Related: [What Can Cause Loss of Smell?](https://breathefreely.com/loss-of-smell/)\] ## Treatments for Loss of Smell & Taste In [Dr. Pasha’s clinic](https://breathefreely.com/), several steps are required in the work-up of olfactory issues to formulate a treatment plan, including [nasal endoscopy](https://breathefreely.com/what-is-nasal-endoscopy/) (a painless microscopic evaluation of the nose), [allergy testing](https://breathefreely.com/education-library/allergy-management/), and a CT scan (X-ray). All tests can be performed in the office. Treatment for loss of smell and taste depends on the cause. For example, if you have [nasal polyps](https://breathefreely.com/education-library/nasal-polyps/), then have them removed. If you have a viral infection, you may need to take medications to reduce the inflammation caused by the infection. For those who have long-standing loss of smell, olfactory training (or smell training) may be beneficial. Dr. Pasha has his own olfactory training regimen that he may provide for you. The future of anosmia management is growing and includes stem cell research and even gene therapy for some congenital causes. Loss of smell can be frustrating for patients. The key is to spend the time necessary to identify the cause so you can focus your therapy. ## Loss of Smell & Taste FAQs ###### What Is Olfactory Training? Olfactory training is a method to restimulate the nose to recognize smell. A simple method is to gather four different major scents. Most common are lemon, rose, cloves, and eucalyptus, usually from essential oils. Place these scents under your nose twice a day. The goal is to try to reconnect the connection of smell with the brain. The method may take months, but there are no risks or high costs. Dr. Pasha and his staff have their own olfactory training program that may be prescribed for you. ###### Do Corticosteroids Work? Corticosteroids in the form of a nasal spray or medication by mouth have variable success rates. Depending on the potential cause of your loss of smell and taste, Dr. Pasha may prescribe a course to reduce the inflammatory damage that affects olfactory nerves. ###### What About Surgery for Loss of Smell? That depends. If the cause of your loss of smell is from the obstruction caused by [nasal polyps](https://breathefreely.com/education-library/nasal-polyps/) or structural blockage, Dr. Pasha may suggest [a procedure](https://breathefreely.com/education-library/endoscopic-sinus-surgery/) to open up your nasal passages.

Having trouble smelling things around you is not normal and could be caused by several conditions. The complete or partial loss of smell is called anosmia and it can be temporary or permanent, depending on what caused it. Loss of smell is usually a symptom of another medical condition.
