Have you had any taste changes following Covid 19?

Want to know if Covid19 can be associated with changes in taste buds?

Is Covid19 related to taste Disorder?

If you want to get information about taste changes in Covid19, read more.


These days, when the whole world is plagued by the new coronavirus pandemic, it will be the right of all people to get the right information from Covid19.

Doctors say that one of the first manifestations of infection with the new coronavirus is a decrease or lack of sense of smell.

With decreased or no sense of smell, your urine may change from the tastes and flavors of foods.

But can the new coronavirus itself change the level and structure of taste buds?

Will the structure and function of the taste buds change during infection of the Covid 19?

In this article, we have collected and presented everything you need to know about Covid 19 and the change of taste.


what you will read next :


Doctors have long known that viral infections are associated with a temporary or transient loss of sense of smell or taste.

Many people with simple viral or seasonal colds report more or less a loss of sense of smell. These people often have a loss of perception of the taste of food. You must have experienced that during a simple viral cold, you did not understand the taste of your favorite foods.

These days, with the increasing prevalence of patients with Covid19, doctors have found that the associated loss of smell and taste is one of the first possible manifestations of a new virus infection in the body.

If you want to know what changes the taste can have while getting Covid19, read on.

The fact that you are experiencing a loss of taste or a decrease in sense of smell following Covid19 indicates that the new virus could have effects on the nervous system and neurons.

In infections and inflammations of the upper respiratory tract, the mucous membranes of the sinus wall and nose become very swollen. The olfactory nerve is located near the nasal mucosa, so following the swelling of the nasal wall mucosa, the transfer of stimuli to the olfactory nerve becomes difficult and the stimulation of the olfactory nerve becomes less and slower. But cold and flu viruses can not directly affect the olfactory nerve themselves.

But in the course of the Covid19, in addition to slowing down the stimulation of the olfactory nerve, a new event occurs, and that is the direct effect of the new coronavirus on the neurons of the olfactory nerve.

If you pay attention to the following statistics, you will better understand the importance of the recent mechanism.

Odor and taste disturbances occur during other viral respiratory infections such as the common cold and seasonal flu, only in two to seven percent of patients, but in patients with Covid19 those rates are up to twenty-seven times higher. There are reliable statistics that say that forty to sixty percent of all patients with Covid19 have some kind of olfactory and taste disorders.

Familiarize yourself with the following terms:

Anosmia means a lack of smell, and in general, a complete lack of smell permanently due to viral infections is far from expected. The most common is hyposmia, which means a decrease in olfactory intensity.

The mechanism of olfactory and taste reduction in Covid19 is different from traumas and injuries to the brain.

We have said that in humans a high percentage of our perception of tastes depends on smell and olfactory perceptions, so it will be obvious that taste changes are accompanied by a decrease and lack of smell.

According to authoritative scientific sources, the theories presented about the causes involved in the reduction and loss of sense of smell during the Covid19 are presented as follows:


Odor transfer hypothesis on the surface of olfactory nerve cells and in fact disorder of olfactory nerve cell surface receptors

Researchers today consider this hypothesis to be bolder and stronger.

Inflammation of the small arteries that supply blood to the olfactory nerve. During nausea, nineteen inflammations form in the wall of the small arteries of the olfactory nerve that are likely to be involved in olfactory and taste-related changes. And eventually a decrease in olfactory perception due to congestion of the nose and sinuses, which in all cases of infections and inflammation of the upper airways are and will be involved.

So far, doctors and researchers have come to the conclusion that the new coronavirus can be harmful directly to olfactory neurons at the level of the olfactory nerve.

Can Covid Nineteen affect other nerve cells as well?

Can the Covid virus directly damage our taste buds?

Is there involvement of other neurons in the covid19?

Will people with covid19 have other brain and nerve damage?

Researchers already know that the new coronavirus will infect the lungs more than any other tissue or organ. The lungs will be the main target organ in the Covid19.

But the nature of the new corona virus is such that it is associated with inflammation of the walls of the body’s arteries, so there is a possibility that the arteries of all organs of the body will become inflamed and the organ will be damaged as a result of this inflammation.

With the same mechanism, the kidneys, liver, brain, etc. are also involved.

Complications such as strokes have been rare and have been reported with few reports.

People who develop neurological symptoms such as headache, delirium, and confusion following Covid19 may not have had their cerebral arteries damaged by the new coronavirus.

Because covid19 is associated with fever and decreased arterial oxygen saturation. These manifestations may be in response to fever and inflammatory and inflammatory mediators, or may be due to impaired oxygen delivery to brain cells.

Doctors say it is too early to identify any symptoms manifested by the central nervous system as a direct and immediate attack of the new coronavirus itself on neurons and the brain.

Twelve pairs of nerve fibers exit the brain; which doctors call the cranial nerves. The olfactory nerve (the first pair of cranial nerves), has been the only nerve that has been damaged since the onset of the new coronary pandemic in patients with Covid19, no other cranial nerve injury has been recorded so far. Damage to the olfactory, Anosmia, hyposmia, and taste-related nerves has been transient and temporary.

We have said that doctors say that the new corona may have a direct effect on the olfactory nerve neurons, But the fact that the majority of people with olfactory dysfunction recover following Quid nineteen is a bit far from the above hypothesis, and more research is needed in this field.

Extensive study has been done in this case and during this statistic was obtained.

In the vast majority of cases with Covid19, five percent of all patients had anosmia or loss of smell, and six percent of all patients in the study experienced loss of taste.

In Italy, there is evidence of an association between olfactory and gustatory disorders and fever following the development of new coronary arteries, and research has shown that anosmia or hyposmia may be an early manifestation in patients.

In this study, it was important to note that the presence of olfactory and taste disturbances in the study group was not associated with congestion and nasal congestion. Another study was conducted in Europe, and following the results, doctors said that two out of every three Germans with Covid19 had experienced a lack of smell.

It may be possible to use olfactory changes as an indicator of patient identification, although this method is not yet recommended.

Researchers in this study suggest that the new coronavirus itself may not only affect olfactory neurons, but also gastrointestinal receptors, causing damage to them. In any case, there is no correct and proven answer for the type of damage and the duration of the damage.

But during the corona pandemic, the number of people who suddenly experience a decrease or loss of smell and marked changes in taste has increased dramatically.


Recognize the common symptoms and manifestations of nineteen queues

According to last year’s studies, forty to sixty percent of cases with Covid19 will complain of some olfactory and taste disorder, but so far these symptoms have not been recorded in official protocols.

Recent studies indicate that more than 80% of people with a positive PCR test have olfactory complaints and a lack of taste. Despite all the differences in the anatomy and structure of the human body, on average every human being has about ten thousand taste buds on the tongue, and we know that every area of ​​the tongue is sensitive to a taste.

In other words, the taste buds are very small sensory organs that make the human senses perceive a variety of flavors.

Every one to two weeks, our taste buds are renewed

There are bumps on the back of our tongue that doctors call papillae.

If the taste buds become inflamed, swollen, and more prominent, there may be swelling of the tongue during swelling and inflammation of the taste buds.

Doctors believe that persistent inflammation and swelling of the taste buds can cause impaired taste bud function and impair the ability to perceive flavors, in other words, cause the affected person’s sense of taste to change and be damaged.

Inside each of your taste buds are tiny bumps called microvilli that are thinner than the fibrous fibers. These microvilli have sensory receptors and are actually the cells that can transmit messages to the brain so that we can Understand the taste of food. Any disturbance in the microvilli will be associated with a disturbance in taste.


Causes of inflammation and swelling of the taste buds include:

Doctors attribute many causes to damage to the taste buds.

The cause of taste bud damage will need to be carefully investigated. The causes of inflammation that cause swelling and taste bud damage in humans are as follows:

It is necessary to say that sometimes the inflammation and swelling of the taste buds is caused by more important and serious problems, for example, cancers of the mouth and tongue can be associated with taste disorder due to damage to the taste buds, so take long-lasting taste disorders seriously and be sure to go to a medical clinic for a checkup by a doctor.


Do you know what a damaged taste bud looks like?

Normally when your taste buds are healthy, the color of the papillae will be very white or pink or red. Sometimes some papillae are seen as a small blister. Doctors call these blisters, tongue pustules. Normally you will not be able to see the taste buds with the naked eye.

Your taste buds are renewed every one to two weeks, so it is obvious that the buds that are inflamed and swollen will be renewed after two weeks with fresh and healthy taste buds, If the underlying inflammatory factor persists, the new taste buds will also become inflamed and swollen. If the underlying disease resolves or is controlled with treatment, the swelling and inflammation of the taste buds will improve.

Statistics say that in the United States, the incidence of taste bud disorder, which leads to a decrease in the strength and intensity of taste, will be two hundred thousand people.

If you are one of the people who have a chronic lack of taste, be sure to see a doctor for a quick check-up. The doctor will record your history.

They ask about your underlying illnesses and previous history of illness in yourself and your family, write down your medication list, use direct observation to examine your swollen taste buds, and The doctor will also use a series of taste tests during clinical examinations that use special compounds and flavors

If there is any suspicion of oral and tongue cancer, a biopsy will be performed.

During infection with the new coronavirus, papillae and taste buds may also become inflamed and swollen, and as a result of this inflammation and changes, you may experience a loss of taste. As time goes on and the infection clears from your body, swollen taste buds will gradually be replaced by healthy buds and you will regain your sense of taste.

In general, the treatment of inflammation and swelling of the taste buds is a very important underlying cause

In viral, bacterial, and fungal infections, elimination of the underlying infection is necessary.

Physicians will benefit from appropriate antibiotics for bacterial infections and antifungals for fungal infections if there are bacterial or fungal infections. Smoking should be stopped in people with swollen taste buds

In addition to treating the underlying cause of swelling and inflammation of the taste buds, which will be the mainstay of taste recovery, Doctors also recommend the following to restore the sense of taste faster:

Drugs such as:

People with underlying heart, kidney and liver diseases should definitely see a doctor when choosing antacids. If the choice of antacids is made, it will definitely be associated with electrolyte irregularities in your body.

During infection with the new coronavirus, the taste buds or papillae become inflamed and damaged, disrupting your sense of taste. Also, swelling in the taste buds will not be unexpected, in most cases, with the recovery of Covid19, inflamed and swollen taste buds will be replaced with healthy taste buds.

It is natural that not understanding the tastes, in addition to reducing the underlying appetite due to the Covid19, will make you less inclined to eat and lose weight. Do not worry, try to speed up your recovery process by drinking plenty of fluids.
