What To Do If You Suddenly Lose Your Sense Of Smell
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.
How You Can Help
Both the GCCR and SmellTracker studies are actively seeking participants. If you have or recently recovered from any kind of upper respiratory illness, youre eligible for the GCCR study whether youre healthy or not, you can participate in the SmellTracker questionnaire.
The researchers are hoping to get hundreds, if not thousands, of responses from around the world.
Sobel says that on an individual level, tools like SmellTracker help patients manage their own health, but drawing conclusions about the symptom at a broader level will only be possible if the researchers gather large amounts of data.
Reed says its been inspiring to see the global scientific community come together to better understand COVID-19. People have just left behind their ideas about territoriality and science and are just working together. Its an amazing thing.

Primary Care Doctor Or Urgent Care
See your doctor or go to a local urgent care clinic if you develop any of the following symptoms:
- mild, intermittent shortness of breath
- mild, intermittent chest or abdominal pain
- persistent coughing
- low-grade fever of 100.4°F to less than 103°F that lasts more than 3 days and does not improve with cooling measures
Q: How Common Is Smell And Taste Loss In Covid
Up to 80% of people who test positive for COVID-19 have subjective complaints of smell or taste loss. That percentage rises when these patients are tested using objective methods that measure smell function. Most patients first notice problems with their sense of smell, but because smell is necessary to taste flavor, the symptoms are often connected.

When Should You Get A Covid
- Tests for COVID-19 include the polymerase chain reaction diagnostic test, which is a nasal swab.
- Theres also an antibody test, a blood test that may be able to tell whether you had an infection in the past.
- The incubation period for the new coronavirus is around 5 to 7 days, but it can be up to 14 days.
All data and statistics are based on publicly available data at the time of publication. Some information may be out of date. Visit our coronavirus hub and follow our live updates page for the most recent information on the COVID-19 pandemic.
As more testing for COVID-19 rolls out, you may be wondering whether you should get tested.
Tests for COVID-19 include the polymerase chain reaction diagnostic test, which is a nasal swab. Theres also the antibody test, a blood test that can tell whether you had an infection in the past.
So, should you wait till you have symptoms to go ahead and get tested? Or is it worth it to see whether you had an infection in the past?
Recovering From The Loss
The good news is that olfactory neurons are capable of regeneration. The bad news is that not everyone will return to his or her pre-COVID level of functioning. And, sadly, some of us might never regain our sense of smell or taste at all. According to some experts, patients with post-viral loss of smell have roughly a 60% to 80% chance of regaining some of their smell function within a year. Since the sense of smell usually diminishes due to age, the recovery could take longer and be less than complete for older adults.
What Can Loss Of Smell Tell Us About The Severity Of Infection
In one study, almost55 percentof people who lost their sense of smell had a mild form of the disease. People who survived severe cases reported a loss of smell only about 7 percent of the time.
Its not yet known why this is so. It could just be that there are so many more mild cases out there. It could also be due to a persons immune system. People with mild cases of COVID-19 may have better immune responses within the cells of their noses, limiting the viruss spread to other parts of the body. Further research can help clarify the reasons.
Tips And Coping Strategies
In my practice with patients with post-COVID losses, and in my own recovery, I have found the following coping strategies helpful.
- Acknowledge your feelings about the loss.
- Consult with an ear, nose, and throat specialist for guidance.
- Consider adjusting your cooking in favor of spicier foods.
- Maintain hope for recovery.
- Cultivate a sense of gratitude: you have survived a potentially lethal disease.
- For additional help, see a counselor or join a support group.

R: Another In The Growing List Of Sars
For example, a recent review which looked at eight studies with a total of 11,054 Covid-19 patients found that loss of smell and taste symptoms were present in 74.9% and 81.3% ambulatory as well as hospitalized, mild-to-severe cases of Covid-19 patients, respectively. The review also found that more than half of them had those symptoms appear before any other Covid-19 symptoms.
Another study, conducted by University College London with 590 people who had lost their sense of smell or taste earlier in the year, found 80% had coronavirus antibodies.
Of those people with antibodies, 40% had no other symptoms.
So not only might losing your sense of smell and taste be the first symptom, it could be the only symptom.
“Because of that, clinicians should consider a patient’s loss of smell and taste an early indication of infection, one that is monitored closely while keeping that patient isolated, and possibly quarantined, until a definitive diagnosis can be made. While many people show evidence of Covid-19 infection in the lungs, we found there could be more at play than what a person’s lungs can tell us,” said Bax.
In addition to surveying for symptoms the researchers also looked at their blood work to see if there were certain biomarkers of inflammation.
Screening For Smell Loss
Until there is a readily-available smell screening test, Yan says a simple self-reported yes-or-no question related to smell loss is very reasonable as a screening question for COVID-19. She’s been using this method at her hospital since April.
One of the recent studies she and other GCCR members participated in showed that loss of sense of smell was the best predictor of COVID-19. The authors say loss of smell was more sensitive and specific than all other symptoms of the virus, like cough or fever.
According to Yan, the National Institutes of Health already called for grant proposals related to developing screening tools for loss of sense of smell in cases of COVID-19. These screening tools would ideally be easily accessible, quick, cheap, and mass-produced.
Still, Yan says this type of screening should be used in tandem with other COVID-19 diagnostic tests.
I would caution that using smell loss as the sole screening modality may also not be advisable, as we do not know if all COVID-19 subjects demonstrate measurable smell loss, Yan says, adding that most studies have shown they do not. Also, we have to be sensitive to those with chronic smell loss that predates COVID-19.”

Adalja also stressed it wouldnt be practical to have people actually smell something to test their senses in airports and other public places. Instead, he believes they should just be asked about any altered sense of smell as part of the screening process.
There are apps and ways to go through a checklist and ask, Do you have any of these symptoms? If you do, you step out of the line and get an evaluation, Adalja said.
Its important that we be inclusive of all the symptoms that we know are consistent with coronavirus.
Borsetto and Jatana advised people to monitor themselves and pay attention to any changes in their usual sense of smell or taste. Rather than relying on a medical smell test, its extra important to be self-aware during the pandemic, Borsetto said.
In view of a possible second wave, realize by yourself that you are experiencing a smell loss, he noted.
Individuals who feel they have had a change in smell or taste from their baseline, should self-quarantine and get tested for the coronavirus, Jatana added.
/7can It Be An Indicator Of A Healthy Recovery
Hence, if the latter is the only symptom you are showcasing, and do not record high temperature or other typical symptoms of the infection, it may indicate a healthy and comparatively easier recovery on your part.
Strangely, there is also another study which suggests how the loss of smell and taste may be an indicator of positive recovery for COVID-19 patients. As olfactory senses recover and regenerate from a viral bout, they misinterpret certain connections and make you experience an altered sense of smell and taste. As they regrow, it takes a while before you get your normal sense of smell back.

Despite Symptoms Its Not The Flu
COVID-19 is not the flu.
As one of a class of pathogens known as coronaviruses, its actually more closely related to the common cold than the seasonal flu.
However, despite some overlap, the typical symptoms of COVID-19 are more similar to the flu than the common cold .
The new delta variant of COVID-19, however, may have more cold-like symptoms.
In terms of differentiating between flu and COVID-19, it can be almost impossible to distinguish, Dr. Jake Deutsch, co-founder and clinical director of Cure Urgent Care centers and Specialty Infusion in New York. Thats why people are recommended to have flu vaccinations so it can at least minimize the risk of flu in light of everything else.
Fevers, body aches, coughing, sneezing could all be equally attributed to them both, so it really means that if theres a concern for flu, theres a concern for COVID-19, Deutsch said.
If you have a mild case of COVID-19, the flu, or a cold, treatment is geared toward management of symptoms, said Cutler.
Generally, acetaminophen is recommended for fevers, he said. Cough drops and cough syrups can also help keep mucus secretions thinner. If there is associated nasal congestion, antihistamines may be useful.
/7why Is Loss Of Smell And Taste Such A Confusing Covid Symptom
Anosmia or a loss of smell remains to be one of the most puzzling symptoms related to COVID-19. What started off as a mild, rare symptom which affected only a small percentage of COVID-19 patients is now being predominantly reported across the world. For many, a loss of smell and taste can be so severe, it can take weeks and months before the senses get back to normal.

What We Know About Covid
Carol H. Yan, MD, who is a part of the Global Consortium for Chemosensory Research , a global research consortium that studies smell and taste loss as it relates to COVID-19, says the loss of smell and taste in COVID-19 patients is often profound and sudden, and sometimes the only presenting symptom.
We have found that at least partial recovery most often occurs within two to four weeks of symptom onset, Yan, who is also an assistant professor in the department of surgery at the University of California, San Diego, tells Verywell.
Even though most people recover the senses within two to four weeks, that doesnt mean they return completely to normal. Its not yet known why some people recover taste and/or smell after losing it from coronavirus, Yan says. One study found around 11% of patients had a persistent smell or taste loss after one month. COVID-19 patients can recover, test negative, and continue to have smell and taste loss.
The persistence of symptoms does not indicate continued viral burden and viral transmissibility, Yan says, explaining that you’re not contagious even if your anosmia persists.
Her Incredible Sense Of Smell Is Helping Scientists Find New Ways To Diagnose Disease
In 2006, scientists from the University of California, Berkeley reported that they’d trained humans to track a trail of chocolate essential oil laid down in an open field. The humans weren’t nearly as good at the task as the dogs were, but did get better with practice.
So how come I can’t even smell a freshly opened bar of chocolate?
How common are smell disorders?
I’m far from alone in my deficit. The National Institute on Deafness and Other Communication Disorders, the division of the National Institutes of Health that deals with taste and smell, says 23% of Americans over age 40 report some alteration in their sense of smell, as do 32% of those over 80 and that’s from data gathered long before the COVID-19 pandemic. Some folks can’t smell anything at all that’s called anosmia. Others, like me, have only a partial sense of accurate odor detection hyposmia. Some smell one thing for another that’s parosmia. And then there’s phantosmia, where people smell things that aren’t there at all.
What else besides COVID-19 can damage the sense of smell?
Why my problem didn’t go away when the swelling resolved is anyone’s guess, but the original insult likely came from a virus.
“It’s been really hard to put various viruses into humans and see what parts of the olfactory system they actually disrupt,” says Dalton.

Coronavirus And The Heart
The findings also offer intriguing clues into COVID-19-associated neurological issues. The observations are consistent with hypotheses that SARS-CoV-2 does not directly infect neurons but may instead interfere with brain function by affecting vascular cells in the nervous system, the authors said. This requires further investigation to verify, they added.
The study results now help accelerate efforts to better understand smell loss in patients with COVID-19, which could in turn lead to treatments for anosmia and the development of improved smell-based diagnostics for the disease.
Anosmia seems like a curious phenomenon, but it can be devastating for the small fraction of people in whom its persistent, Datta said. It can have serious psychological consequences and could be a major public health problem if we have a growing population with permanent loss of smell.
The team also hope the data can help pave inroads for questions on disease progression such as whether the nose acts as a reservoir for SARS-CoV-2. Such efforts will require studies in facilities that allow experiments with live coronavirus and analyses of human autopsy data, the authors said, which are still difficult to come by. However, the collaborative spirit of pandemic-era scientific research calls for optimism.
/7covid And Loss Of Smell And Taste
Loss of smell, which can also go on to affect your ability to taste normal food can also be quite debilitating and frustrating for people who experience this ‘mild’ COVID symptom. Even so, many experts believe that experiencing loss of smell or taste, coupled by appetite reduction may be a good sign of the infection, as it may protect people from experiencing the other lethal signs of COVID-19, i.e. respiratory and inflammatory attacks.
Many doctors are now saying that people who experience complete loss of smell and taste, with gastrointestinal symptoms such as cramps, diarrhoea may only suffer from a mild form of novel coronavirus, which has now impacted over 55 million people across the world. Not only does loss of smell and taste have no medicinal therapy, but it could also mean that they have safeguarded themselves from severe respiratory attacks, which usually kick in from week 2 of COVID infection.
According to Indian doctors who have been working on mapping the signs and symptoms of COVID-19, patients with a moderate or severe form of the disease, who require critical ICU care rarely report experiencing a sudden loss of smell as a symptom, which could imply that it is largely a good ‘prognosis’ and only a mild form of COVID-19.
