Why Does Covid Cause Loss Of Smell

Treatment Options For Loss Of Smell

Coronavirus Symptoms: How Do You Lose Your Sense Of Taste & Smell?

Outside of waiting for your sense of smell to return on its own, there are a few things that can help it along. Some research suggests that topical steroids and certain supplements may help; these are options you may wish to discuss with your healthcare provider.;

Additionally, olfactory training is also an option. It involves a routine of smelling various scents and then reflecting on and visualizing what each one actually smells like. Its thought that this combination of recognizable smells and visualization helps retrain the pathways to the brain and can speed up recovery from loss of smell.;

We are hopeful that as researchers and doctors continue to learn more about COVID-19, new forms of treatment and advancements in medicine will follow to provide more answers for the virus symptoms.

What We Know About Covid & Loss Of Smell

Besides complete loss of smell , COVID can also cause the qualitative disturbance of smell and distortion of the perception of a smell. These are called dysosmia and parosmia respectively. Out of the 86% of people who experienced any of the three, nearly 55% had only mild cases of COVID-19. Why? Its suspected that they have higher levels of antibodies that prevent the spread of COVID to the nose.;

In any case, loss of smell has become an early indicator of the likelihood of a severe case of COVID. And although it mainly seems to affect individuals with mild COVID cases, the impact can still be far-reaching. Dr. Carolyn Word of the Charleston Allergy & Asthma team is one example of this.;

More than 60 days after her bout with the virus, she still had not fully recovered her sense of smell. She said, For example, if Im standing right over the stove, I can smell bacon but not the smell wafting through the house. I cant detect smells in the ambient air; they have to be physically under my nose. But a month ago, I couldnt smell anything right under my nose so Im hopeful that this is a sign that Ill continue to improve.

Thousands of people have had similar experiences. While most recover their sense of smell within 3 weeks and certainly before the 60-day mark, not all are so fortunate. In one study, close to 25% of affected people suffered from loss of smell for more than 60 days and 5% for 6 months. And only time will tell if this could be a permanent issue for some.;

Our Rating: Missing Context

Based on our research, we rate MISSING CONTEXT the claim alpha-lipoic acid can help regain a sense of smell and taste lost;because of COVID-19. While;one limited study of the antioxidant showed it could help someone who lost their sense of smell, experts say there isn’t enough strong scientific evidence yet supporting its effectiveness or safety in extended usage.

What Are Some Resources For People Who Are Affected By Anosmia

There are resources available to people who have smell and taste loss, though some of these arent just COVID-19 related. The Global Consortium for Chemosensory Research is a group of scientists who came together very quickly in the spring of 2020 to study the effects of smell and taste loss. You can participate in our research so we can learn more about whats causing this and how to deal with it. There are links to many other resources on the site.

There are also people and organizations doing smell training. Smell training is essentially smelling the same odors over and over so that you can retrain your bodys ability to detect and identify that odor. We are optimistic that the sense of smell will come back for some of the people who lose their sense of smell for several months. One of the groups that is involved in smell training is the nonprofit Abscent. It wasnt set up specifically for COVID-19 patients but has been a pioneer in smell training.

Can It Be Treated

How Covid

With post-viral issues as well as with other occurrences caused by chronic sinusitis, aging, Parkinsons, trauma and, occasionally, congenital cases Dr. Sindwani says that steroids, either by mouth or topical nasal steroids, can also work.

Data is lacking on this, but the thought is that these steroids can reduce inflammation in parts of the nasal cavity or in these smell receptors which are inflamed, he says.

Nasal polyps and chronic;sinusitis are the most common problems, he says, noting there are treatment options, including surgery, for those issues. Whether its medication or surgery, there are options. We treat what we know at first, says Dr. Sindwani. If its polyps or a sinus tumor, those have their own specific treatments. The loss of smell is actually a symptom of the problem.

He also notes that, while theres still plenty of research left to do on anosmia treatment, theres been recent interest in how consuming omega-3 fatty acids and other supplements could help the sense of smell recover.

How Is This Affecting People Over The Long Term

COVID-19 affects the nervous system and sometimes results in profound loss or a complete inability to smell. Some people recover their ability to smell within a few days or weeks, but for some people its been going on for much longer. Scientists are still not sure how many people lose their ability to smell completely, a condition known as anosmia.

This is really taking its toll on the people who have not had their sense of smell, sometimes for months, or even upwards of almost a year at this point. It can have real consequences. For example, if you cant smell smoke, you are relying on a smoke detector to tell you theres a fire. It is also affecting quality of life. Food doesnt taste good anymore because how you perceive taste is really a combination of smell, taste and even the sense of touch. Some people are reporting weight loss due to loss of appetite, and theyre just not able to take pleasure in the things that theyve previously found pleasurable.

Lost Sense Of Smell Returns For Almost All After Covid

HealthDay Reporter

THURSDAY, June 24, 2021 — A year on, nearly all patients in a French study who lost their sense of smell after a bout of COVID-19 did regain that ability, researchers report.

“Persistent COVID-19-related anosmia has an excellent prognosis, with nearly complete recovery at one year,” according to a team led by Dr. Marion Renaud, an otorhinolaryngologist at the University Hospitals of Strasbourg.

Early in the pandemic, doctors treating people infected with SARS-CoV-2 began to realize that a sudden loss of smell was a hallmark of the illness. It’s thought that COVID-linked “peripheral inflammation” of nerves crucial to olfactory function is to blame in these cases.

But as months went by, and many patients failed to recover their sense of smell, some began to worry that the damage could be permanent.

The new study should ease those fears.

In their research, the French team tracked the sense of smell of 97 patients averaging about 39 years of age. All had lost their sense of smell after contracting COVID-19.

The patients were asked about any improvements in their smelling ability at four months, eight months and then a full year after the loss of smell began. About half were also given specialized testing to gauge their ability to smell.

Overall, 96% of the patients objectively recovered by 12 months, Renaud’s team reported. The study was published online June 24 in JAMA Network Open.

One of COVID-19s many mysteries may finally be solved.

Researchers at Harvard Medical School say theyve discovered why some people infected with the coronavirus lose their sense of smell.

The symptom, called anosmia by doctors, is one of the earliest and most commonly reported indicators of the virus.

Some studies suggest it could actually be a better way to predict whether someone has the disease than other well-known symptoms like fever and cough.

But, until now, scientists had been baffled by exactly how some patients were being robbed of their senses.

The researchers set out to better understand how smell is altered in coronavirus patients by pinpointing the cell types most vulnerable to SARS-CoV-2, the virus that causes COVID-19.

Through their analysis of various datasets, they found that it attacks cells that support the olfactory sensory neurons, which detect and transmit the sense of smell to the brain.

Our findings indicate that the novel coronavirus changes the sense of smell in patients not by directly infecting neurons but by affecting the function of supporting cells, said Sandeep Robert Datta, a neurobiology professor at Harvard Medical School and co-author on the paper.

What To Do If You Suddenly Lose Your Sense Of Smell

Diarrhea, loss of smell and appetite commonly reported in coronavirus patients

If you experience a loss of smell, Overdevest said there are things you can do that may help you get it back, besides simply waiting it out.

The best level of evidence supports integrating an olfactory training protocol into your routine, he said. This protocol focuses on using sets of essential oils to stimulate both the perception of that oils smell as well as the imagery of that scent.

According to Overdevest, one of the oils included in this protocol is rose oil. The idea is to smell the scent in brief whiffs then to reflect on what roses previously smelled like and overall imagery of roses.

He added that other treatments that have varying levels of evidence include topical steroids, and numerous supplements.

A clinical trial currently underway is looking at omega-3 fatty acid supplements as a possible method to treat loss of smell. Theres also evidence that one essential mineral can cause it if used in excess.

Loss Of Smell Associated With Milder Covid

  • About 86 percent of people who have COVID-19 lose some or all of their ability to smell.
  • But the majority who lost their sense of smell experienced a mild form of the disease, according to new research .
  • Researchers think that patients with mild illness may have higher levels of certain antibodies that limit COVID-19 from spreading to the nose.

A loss of smell has become a hallmark symptom of some COVID-19 cases. Now experts are learning how this symptom may reveal whether a person is likely to have a severe case.

About 86 percent of people who have COVID-19 lose some or all of their ability to smell. But the majority who lost their sense of smell had a mild form of the disease, according to new research published this week.

Researchers say the reason for this isnt well understood. But they think that patients with mild illness may have higher levels of certain antibodies that limit COVID-19 from spreading to the nose.

However, a definitive answer remains elusive, Dr. Jonathan Overdevest, assistant professor of rhinology and skull base surgery at Columbia University, told Healthline.

What About Loss Of Taste

While most people know about the link between COVID-19 and loss of smell, they may not know that loss of taste can also be a symptom. But the medical community is still debating whether COVID-19-related taste loss is due to the loss of flavor, which is closely linked to smell loss and retronasal olfactory dysfunction. The few studies that have quantifiably measured taste function in COVID-19 patients have yielded conflicting results.

Coronavirus Smell Loss ‘different From Cold And Flu’

Health editor, BBC News online

The loss of smell that can accompany coronavirus is unique and different from that experienced by someone with a bad cold or flu, say European researchers who have studied the experiences of patients.

When Covid-19 patients have smell loss it tends to be sudden and severe.

And they usually don’t have a blocked, stuffy or runny nose – most people with coronavirus can still breathe freely.

Another thing that sets them apart is their “true” loss of taste.

It’s not that their taste is somewhat impaired because their sense of smell is out of action, say the researchers in the journal Rhinology. Coronavirus patients with loss of taste really cannot tell the difference between bitter or sweet.

Experts suspect this is because the pandemic virus affects the nerve cells directly involved with smell and taste sensation.

The main symptoms of coronavirus are:

  • high temperature
  • new, continuous cough
  • loss of smell or taste

Anyone with these symptoms should self-isolate and arrange to have a swab test to check if they have the virus. Members of their household should isolate too to prevent possible spread.

I’ve Lost My Sense Of Smell: Is It Covid


While loss of smell is a symptom of COVID-19, don’t panicthere are a variety of other possible causes, one expert says.

“It can be due to nasal or sinus inflammation, or other viral infections distinct from COVID-19,” explained Dr. Bobby Tajudeen, director of rhinology, sinus surgery and skull base surgery at Rush University Medical Center in Chicago.

“And it can even occur as a result of some neurodegenerative diseases, like Alzheimer’s or dementia, or vitamin deficiencies. Rarely tumors can present with smell loss,” Tajudeen added.

Loss of smell is most often the result of inflammation caused by sinusitis, polyps in the nose and even allergies, and the loss of smell can be progressive.

Treating the inflammatory condition can restore your sense of smell, he explained in a medical center news release.

But a sudden loss of smell can indicate a viral condition.

“Usually when people have a cold, they have congestion and a runny nose, and they can’t breathe through their nose,” Tajudeen said. “At the base level that usually causes a temporary reduction in smell. However, once the congestion resolves, in patients with viral-induced smell loss, their smell does not recover.”

With COVID-19, loss of smell is among one of the first signs of infection.

” usually occurs for those who have a mild form of the virus,” Tajudeen said. “Patients with smell loss are normally at home recovering and not admitted into the hospital or on a ventilator.”

How Important Is Community Science For Public Health

This analysis demonstrates the power of community science apps like the ZOE COVID Study for providing reliable, near real time insights into public health on a mass scale.

Importantly, our research shows that loss of smell is a strong predictor of COVID-19 infection, even in the absence of a test. Although that information may be less useful here in the UK where we have good availability of free testing through the ZOE COVID Study app and the NHS, it could be life-saving in countries with high rates of COVID-19 but little access to tests.

The ZOE COVID Study is the biggest study of its kind globally and has made huge contributions to the COVID response in the UK and abroad. But we couldnât have done any of this without you -Â; our amazing contributors.Â;

Throughout the pandemic, your data has provided valuable insights about whatâs going on with COVID-19 on the ground and helped to change the course of the pandemic.

Weâre not yet at the end of the pandemic. If you havenât already, download the ZOE COVID Study app and join a million other users logging daily health reports and playing their role in the fight against COVID-19.

Stay safe and keep logging.

Is Loss Of Smell Still An Important Symptom Of Covid

Early in the pandemic during 2020, we used symptom reports and testing data from millions of ZOE COVID Study app contributors to confirm that symptoms like loss of smell , fever, and cough could predict whether someone was likely to have COVID-19, even without a test.

Hereâs why itâs still worth watching out for any changes in smell or taste, especially if you donât have access to testing.

Parosmia Post Covid Vaccine

Warning: This is a disgusting but important topic. Avoid if your are squeamish.

Update: There was a survey posted on Reddit for anyone interested in sharing their experience with this condition.

While reviewing Reddit posts of vaccine side effects, I noticed a few instances of people describing how they were emitting a foul, garbagy odor after receiving the injections. This is very concerning because that is often a sign of serious disease, such as circulatory issues or tissue decomposing. Necrosis or gangrene can cause such an odor.

Has anyone else had a bad smell, not just the rancid smell that people speak of after their vaccine? I was fully vaccinated as of two weeks ago and I noticed sometime after the first dose, but much more after the second that there is this horrible smell that I cannot stop smelling. It gets much worse at night. I had Covid near Christmas and actually had a heightened sense of smell rather than a loss of smell or taste.

Smell problems, keep smelling a rancid smell and also overly aware of my own smell, even after showering I feel like I need to shower again, even though no one else can smell anything.

The media doesnt report any instances of people describing the garbage odor post vaccine, only post Covid disease. This is contrary to what is being reported by many people online, such as the above quotes. There are even support groups cropping up. As well, there was no mention of this side effect prior to the release of vaccines.
