What Are The Complications Of Anosmia
People with anosmia may lose interest in food and eating, leading to malnutrition and weight loss.
People with anosmia should make sure to have functioning smoke alarms in their homes at all times. They should also be cautious with food storage and the use of natural gas because they may have trouble detecting spoiled foods and gas leaks.
Recommended precautions include:
Loss Of Sense Of Smell Causes
Depending on the time of year and your allergy history, there are many possible causes for the loss of sense of smell. Loss of smell due to allergies is very common, and thankfully, it can be treated with the help of a professional allergist who has a proven track record of sinus treatments. No matter how uncertain you are about your loss of smell, always know that it is crucial to get the opinion of a professional to prevent any further damage to your sinuses. Sometimes, the loss of sense of smell due to allergies can lead to lead to temporary anosmia. To avoid this, seek help as soon as your symptoms occur.
How Do Taste And Smell Work
Like all senses, taste and smell are possible through specialized receptors. The olfactory receptors in the nose is stimulated by airborne chemical that enter the nose. These receptors then send signals to the brain where it is perceived as odors. Similarly chemicals that dissolve in the saliva within the mouth stimulate the taste buds. These receptors send signals to the brain which is perceived as certain tastes.
It is important to remember that smell and taste are linked. Chemicals that are released during chewing may not only stimulate the taste buds but also the smell receptors in the nose. This can heighten the sense of taste. Therefore when smell is compromised, taste sensitivity is reduced and vice versa. Therefore a problem with one sense impacts the other although there may be no concomitant disorder of the other sense.
There are different medical terms that describe loss of taste or smell.
- is the loss of smell. This term describes a total loss of the sense of smell . Hyposmia refers to a partial loss of the sense of smell. Another term is dysosmia which refers to any distortion of the sense of smell.
- is a complete loss of taste. Hypogeusia is the partial loss of the sense of taste. a refers to any distortion of the sense of taste. Sometimes there are other disruptions to the sense of taste like a foul taste which is known as cacogeusia.

What Complications Can Arise When The Sense Of Smell Is Recovering
Reiter: One potential issue with recovery from a significant loss of sense of smell can be a distortion of smells. All parts of the system may not recover at the same time and to the same degree. Any complex odor isn’t going to just trigger a response in one receptor. It’s going to trigger responses in a number of different kinds of receptors. And your brain integrates all that information together to say, “Well, that’s a rose,” or “That’s chocolate.” In some people, if they have a significant loss, some of the receptors may recover, whereas others may not, or some may recover to different degrees. That can lead to distortions of odors so things that previously were pleasant odors may be unpleasant. In rare cases we’ve seen people have severe food aversions because they get incomplete recovery of their sense of smell, and it causes such distortion that they lose their appetite.
Loss Of Smell Treatment
The complete loss of smell is called anosmia, while the partial loss is hyposmia. Both conditions can be temporary or permanent, however, total loss of smell is rare. For most people, the loss of smell begins to deteriorate after the age of 60, while the ability to smell is at its peak between the ages of 30-60. In addition, women typically have a better sense of smell than men do.
Loss Of Taste And Smell: How To Get Your Sense Of Taste & Smell Back After A Sinus Infection
July 23, 2021 Written by: Michael Menachof Categories: ,
Dr. Menachof, MD, has specialized in conditions around the head, throat, ear, nose, neck and face for over 20 years, and was the first to bring sublingual allergy drops to Colorado in 2005. He has been recognized as a Fellow by multiple academies, named one of America’s Top Facial Plastic Surgeons continually since 2003 and is featured in multiple national publications.
Experiencing a loss of taste or smell? Learn more about what causes it and how to get your senses back after a sinus infection.
Have you ever noticed that a certain food didn’t taste as good as it used to? Or that a once pungent smell didn’t bother you as much? Maybe you took a whiff of those spring flowers and smelled… nothing! While certainly alarming, this is most likely a result of a very common condition called anosmia, or the loss of your sense of smell.
Since our smell and taste buds are so closely linked, any conditions or irritants that cause swelling in the nasal passages can lead to a loss of smell and therefore taste. While typically just a temporary nuisance, loss of smell can also pose a dangerous threat, as your sense of smell is responsible for alerting you to dangers like gas leaks, rotten food, or fire. And because it affects your sense of taste, it can also lead to loss of interest in eating that results in unwanted weight loss and malnutrition.
What Can You Do
Fortunately, if you’re suffering from this problem there are a range of things you can do to deal with it.
Address the problem of congestion – any loss of taste and smell is often caused by so dealing with this issue first is a good idea. There are many ways to ease a blocked nose including steam which contains moisture and heat that can help break down mucus and soothes inflammation. A hot bath or shower, as well as hot drinks are ideal for exposing your nose to steam.
Address the problem of inflammation – inflammation is largely behind the loss of taste and smell so addressing this issue might improve your situation. One way to do this is to try an anti-inflammatory remedy such as Devil’s Claw which helps to minimise this problem. Herbal remedies are often preferred when it comes to allergic rhinitis as they don’t cause any nasty side effects that conventional medicines might.
Avoid food and drinks high in histamine – for those with allergic rhinitis histamine is also at the root of any loss in taste and smell so you’ll want to avoid giving your body more of this chemical in case it worsens the problem. This means avoiding food and drinks that are high in histamine such as caffeine, alcohol, smoked meat and cashew nuts. As an alternative, there are plenty of foods low in histamine such as eggs, fresh fruit and vegetables, herbs, herbal teas and fresh chicken.
Is It An Allergy Or Covid
When COVID-19 and seasonal allergies are circulating at the same time, every sniffle can lead you to worry that you might have the virus. “From the perspective of a parent, one of the biggest issues is when kids in school have allergy symptoms that are poorly controlled, and then the school system sends them home or says they need a physician’s note,” Dr. Leeds says.
The CDC has a Venn diagram that shows symptoms the two conditions have in common. These include congestion, cough, difficulty breathing, fatigue, runny nose, sore throat, and shortness of breath. But comparing the most common symptoms reveals clear differences. Seasonal allergies usually cause itchy or watery eyes and sneezing, while COVID-19 is characterized by fever and chills, muscle and body aches, new loss of taste and smell, nausea and vomiting, and diarrhea.
“Because of COVID-19, people are afraid of you when you’re sniffling,” says Dr. Hsu. “But it goes both ways—a lot of people are sniffling and sneezing and coughing, and they are not getting tested for COVID-19, because they assume it’s allergies. And they are probably correct.”
Often the distinction is clear—people with allergies itch more, and they don’t have the fatigue, malaise, and fever that comes with COVID-19. But anyone who is concerned should call their doctor, she says.
Why To Seek Medical Attention
Our senses of smell and taste are important for our nutritional status and individuals who lose these senses often lose weight. Our sense of smell can also warn us of danger – smoke from a fire, chemicals, a natural gas leak. Diagnosing problems with taste or smell is generally uncomplicated. You should see an otolaryngologist . This doctor, who specializes in disorders of the ear, nose, and mouth, will probably have you try to identify certain chemical odors using a standard “scratch and sniff” test, and/or flavors .
What Is Allergic Rhinitis
The immune system would usually ignore things like animal dander,, mould spores and as these do not pose a significant threat to the body in the way that the likes of a virus would. However, when suffering from allergic rhinitis the exact opposite is true as the immune system reacts negatively to these things and as a result, attempts to fight them off. One way of doing this is through the release of histamine – a chemical that causes all sorts of problems including inflammation and itching. There are other troublesome symptoms too though, that have further implications for the body.
Can Taste Loss Be Treated
Sometimes losing your sense of taste is only temporary but sometimes it is permanent. For example, nasal polyps can be removed surgically but lost cells due to the normal aging process cannot be replaced.??
Permanent Loss:
- Acute infections like strep throat after resolution
- Allergies can be treated with antihistamines
- Smoking can reverse if you quit smoking
If you are taking medications that cause dry mouth they can affect the way you taste food. This is because saliva contains important chemical messengers that are necessary for the brain to interpret tastes. In this case, you can talk to your doctor about changing to another medication or ways to cope with dry ?mouth, such as chewing sugar-free gum and drinking a lot of water.
It is important to seek resolution of loss of taste if possible due to the nutritional and social aspects involved in taste. Malnutrition and depression can result from prolonged or untreated loss of taste. If the loss of taste is permanent, it is important to work with your medical team to minimize your nutritional or depression risks.??
Similar Symptoms Seasonal Allergies Vs Covid
For most people, spring and early summer are when they are likely to be bothered by allergy symptoms. During normal years, allergies are shrugged off as minor annoyances that can usually be managed with over-the-counter medications. But this year, with the threat of coronavirus still a top concern, some symptoms of allergies may be confused with COVID-19. To help you understand what is probably an allergy versus something more serious, this comparison of symptoms may help:
How Is Yale Medicine Unique In Its Approach To Anosmia
At Yale Medicine, we take the time to identify the cause of your smell disturbances and identify appropriate treatment. “While changes in smell are quite common,” Dr. Manes says, “they can be the first sign of something more serious. At Yale Medicine, we are able to appropriately and accurately investigate the actual cause.”
What Allergy Treatments Are Available
Treatments can help a great deal, says Dr. Hsu. “Allergy treatment has changed over the past 10 years, with a number of first-line medications now available over the counter,” she says. “So, while we have lots of consultations with patients, we don’t necessarily send a prescription to the pharmacy. We often advise people on what to buy—but we want to be very specific, because there are certainly a lot of over-the-counter medications that we would not recommend as first-line treatments.”
For instance, she might start with antihistamines for itching and runny nose, steroid nasal sprays for nasal passage congestion, and antihistamine eye drops for ocular symptoms. If a patient is still uncomfortable, she might recommend a decongestant, but not for daily use, since it’s a medication patients can become overly reliant on. Likewise, some patients should avoid antihistamines that are excessively sedating, she says.
The problem is that some people… think they’ll just grin and bear it. But… you can take steps to minimize those weeks of misery.Yale Medicine pediatric allergist Stephanie Leeds, MD
It’s helpful when patients have a skin or blood test to find out exactly what they are allergic to. “If you are really symptomatic, it’s helpful to get tested at least once. I don’t think you need to be re-tested year after year, but at some point, establishing the specific triggers can be helpful, because then you can take steps to avoid exposure,” Dr. Leeds says.
Focus On Stress Management
Stress can lead to digestive issues, sleeping difficulties, and fatigue. Stress may also exacerbate underlying health conditions, such as depression, fibromyalgia, and Crohn’s disease. The following activities may help a person manage their stress levels:
- regular exercise
Short term appetite changes and tiredness are not usually a cause for concern. These symptoms may occur as a result of a minor illness or be due to a change in the diet or sleep habits.
However, a person should see a doctor if they:
- experience persistent appetite loss or tiredness that does not improve in response to altering the diet or getting better quality sleep
- experience appetite loss or tiredness after starting a new medication
- have an underlying medical condition, such as , heart disease, or
Children and infants who experience tiredness and appetite loss may have difficulty communicating how they feel. If a child seems weak and overly tired or refuses to eat, a parent or caregiver should take them to see a pediatrician.
Medication Side Effects Compromise Smell Taste
The various medications used to treat allergies often have a significant list of undesirable side effects. This is one of the reasons that allergen avoidance should be practiced to the fullest extent possible by utilizing all the tools available for environmental control of allergens.
Corticosteriods are one category of medications used to treat inflammation by blocking allergic reactions. They come in many forms, including pill or liquid ingestible forms, nasal sprays, inhalable, eyedrops, and skin creams. While each type poses unique side effect risks, nasal and inhaled corticosteroids are more likely to affect taste.
Nasal corticosteroids include the medications Flonase and Nasonex, among others, and may cause an unpleasant smell or taste and nasal irritation, which obviously would affect the ability to taste. Inhaled corticosteroids, used to relieve allergic asthma, include Azmacort, Aerobid, and Flovent, and may lead to infection in the mouth, though this side effect is rare.
Nasal antihistamines and decongestants can also cause smell/taste issues. Side effects of nasal spray antihistamines, which block inflammation-causing histamine during the allergic response, include a bitter taste, dry mouth, and nasal burning; nasal decongestants, if used for more than about a week, can lead to severe rebound congestion once the medication is discontinued.
How Is Anosmia Treated
Your physician will examine you to determine the cause of your smell disturbance. Because anosmia can result from any number of conditions, your doctor will first address the primary condition that seems to be causing the problem. For example, if you have allergic sinusitis, treating it can help restore the olfactory sense. If nasal tumors, nasal polyps or nasal deformities require surgery, that may be the first step. In other cases, anosmia can be an early symptom of a disease such as Alzheimer’s or Parkinson’s.
However, it’s important to know that sometimes the cause of smell disorder can’t be determined for certain. And sometimes anosmia cannot be treated.
Other Causes Besides Covid
Those who have tested negative for COVID yet are experiencing loss of taste or smell might want to talk to their doctors about retesting. Sometimes, a false-negative test result may occur.
If a repeat test shows that COVID isn’t to blame, it might be time to look at other possible causes. These include:
Q: What Questions About These Covid
We plan to watch the recovery rate for these patients. We encourage people who have prolonged smell and taste dysfunction to be evaluated to help us understand if and when these symptoms resolve. There is also concern that COVID-19 and its ability to enter the olfactory tissue could be a conduit for infection in the brain. I think we’ll learn more about that as we follow these patients over time.
How Is Anosmia Diagnosed
The loss of smell is difficult to measure. Your doctor may ask you some questions about your current symptoms, examine your nose, perform a complete physical examination, and ask about your health history.
They may ask questions about when the problem started, if all or only some types of odors are affected, and whether or not you can taste food. Depending on your answers, your doctor may also perform one or more of the following tests:
- CT scans, which use X-rays to create a detailed image of the brain
- MRI scans, which uses radio waves and magnets to view the brain
- of the skull
When Should I Seek Medical Advice To Determine If I May Have Covid
- Your allergies are not improving after taking over-the-counter antihistamines, nasal sprays, eye drops and/or allergy prescriptions after three to four days and your symptoms appear to be getting worse
- You have developed additional symptoms such as a significant headache, fever, cough, decreased sense of taste or smell or gastrointestinal problems such as nausea, diarrhea or vomiting
- You are experiencing allergy and /or COVID-19-like symptoms and you’ve been exposed to someone with COVID-19
Similar Symptoms But Important Differences
- Eye problems. Pink eye is a possible symptom of COVID-19, and results in red and burning eyes. The itchy and watery eyes caused by allergies is usually mild and bothersome — but not painful.
- Lack of energy and fatigue. While some people may feel run down or lack energy during an acute seasonal allergy attack, they are normally able to continue with their everyday activities. Extreme fatigue, to the point where it’s difficult to get out of bed or take care of basic needs, is much more serious and associated with COVID-19.
- Cough. Some people experience a mild cough along with congestion, runny nose or sneezing when suffering from allergies. If the cough responds to allergy medications, it’s almost certainly nothing to worry about. However, a cough that’s accompanied with a fever or shortness of breath could be a symptom of COVID-19.
- Loss of taste or smell. Seasonal allergies can sometimes affect your sense of taste or smell, but it’s usually mild or comes and goes along with other symptoms. A sudden and complete loss of taste or smell, especially without accompanying congestion, sneezing, or runny nose, is a recently recognized symptom of COVID-19.
If you have been affected by seasonal allergies in the past, and your symptoms are similar to what you’ve experienced before, chances are that’s what you’re dealing with now. And, if your symptoms respond to over-the-counter remedies or medication prescribed for allergies, you can be fairly certain you don’t have COVID-19.
What Research Is Being Done About Taste Disorders
The National Institute on Deafness and Other Communication Disorders supports basic and clinical investigations of smell and taste disorders at its laboratories in Bethesda, Maryland, and at universities and chemosensory research centers across the country. These chemosensory scientists are exploring how to:
- Prevent the effects of aging on taste and smell.
- Develop new diagnostic tests.
- Understand associations between taste disorders and changes in diet and food preferences in the elderly or among people with chronic illnesses.
- Improve treatment methods and rehabilitation strategies.
Some recent chemosensory research focuses on identifying the key receptors expressed by taste cells and understanding how those receptors send signals to the brain. Researchers are also working to develop a better understanding of how sweet and bitter substances attach to their targeted receptors. This research holds promise for the development of sugar or salt substitutes that could help combat obesity or hypertension, as well as the development of bitter blockers that could make life-saving medicines more acceptable to children. Taste cells—as well as sensory cells that help you smell—are the only sensory cells in the human body that are regularly replaced throughout life. Researchers are exploring how and why this happens so that they might find ways to replace other damaged sensory cells.
How Do You Regain Your Sense Of Taste
Determination of the etiological factor is necessary to treat ageusia. Some taste disorders do not require any treatment as they resolve spontaneously. There is no particular therapeutic regime for a taste disorder like ageusia.
If it is chemotherapy-induced, it is potentially reversible by the cessation of the use of offending .
However, discontinuation of drugs to treat the taste disorder is not always possible in patients, particularly with -threatening conditions such as cancer, diabetes mellitus, and uncontrolled infections.
Treating the underlying condition that causes your impaired sense of taste can help restore your taste. Bacterial sinusitis, salivary glands, and throat infections can be treated with antibiotics.
Symptoms of colds, flu, and allergic rhinitis that impact taste may be relieved with decongestants or antihistamines. Once you are feeling better, your sense of taste will most likely return quickly.
Your doctor may prescribe medications to minimize the effects of a nervous system disorder or an autoimmune disease that causes impaired taste.
Supplements are an option, such as zinc gluconate, particularly in patients undergoing radiotherapy/chemotherapy in the dosage of 140mg/day or alpha-lipoic acid in the dosage of 600 mg/day for few months may restore taste.
Treatment For Allergic Rhinitis
Once an allergy is determined, an allergist will develop a treatment plan for each patient. Allergies are often treated with a three-tier approach, avoidance, medication, and immunotherapy. Patients who can avoid the trigger of their allergies or if the usual doses of allergy medications can control their symptoms may not need immunotherapy. , also called allergy shots, have been proven effective against inhalant allergies and stinging insect allergies and may be recommended if the patient’s allergies are not under control.

Why Seasonal Allergies Happenand Only To Some People
Seasonal allergies may be common, but most people don’t seek treatment. Only one in ten Americans experience seasonal allergies serious enough to diagnose. What makes seasonal allergy sufferers different, says Dr. Poole, is often genetics.
“Genetic predispositions play a role to some degree as it is more common to develop allergies if one or both parents have a history of allergies,” she says.
But if one or even both of your parents have allergies, you might still be sniffle-free—and vice-versa; if your parents have zero allergies, you can still have them.
“Allergies can develop at any time during the lifespan. You can grow up with them and they can get better or you can develop them later in life,” Dr. Gupta says.
It’s very personal, which is what makes diagnosing seasonal allergies a challenge. However, a full medical history tracking your response during pollen season might provide clues. Allergists can also conduct skin allergy testing to confirm specific allergies, Dr. Poole adds.
If you have allergies and notice them getting worse over time, you’re not just imagining things, reports a February 2021 study in the Proceedings of the National Academy of Sciences of the United States of America .
“For many of my patients, allergies are getting worse year after year,” Dr. Gupta says.
“Essentially we are seeing an early spring and late fall season. So, even people with ‘seasonal’ allergies are experiencing symptoms almost year-round,” she adds.
