Why Am I Losing My Sense Of Smell
According to Tajudeen, smell loss is most commonly caused by nasal and sinus inflammation. This inflammation can occur due to sinusitis, polyps in the nose and even allergies. It can act as a barrier for smell molecules to enter your nose, meaning you cant physically pick up the smell.
These types of conditions can cause a progressive loss of smell, too. You may notice a gradual decrease in your smelling abilities over a span of several years due to the built-up inflammation in your nose.
This type of smell loss is actually the easiest to treat, Tajudeen explains, because doctors are able to treat the inflammatory condition, enabling you to regain your sense of smell.
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.
When To Seek Immediate Medical Attention

Olfactory Support Cells Not Neurons Are Vulnerable To Novel Coronavirus Infection
This article is part of Harvard Medical Schools continuing coverage of medicine, biomedical research, medical education and policy related to the SARS-CoV-2 pandemic and the disease COVID-19.
Temporary loss of smell, or anosmia, is the main neurological symptom and one of the earliest and most commonly reported indicators of COVID-19. Studies suggest it better predicts the disease than other well-known symptoms such as fever and cough, but the underlying mechanisms for loss of smell in patients with COVID-19 have been unclear.
Now, an international team of researchers led by neuroscientists at Harvard Medical School has identified the olfactory cell types in the upper nasal cavity most vulnerable to infection by SARS-CoV-2, the virus that causes COVID-19.
Surprisingly, sensory neurons that detect and transmit the sense of smell to the brain are not among the vulnerable cell types.
Reporting in Science Advances on July 24, the research team found that olfactory sensory neurons do not express the gene that encodes the ACE2 receptor protein, which SARS-CoV-2 uses to enter human cells. Instead, ACE2 is expressed in cells that provide metabolic and structural support to olfactory sensory neurons, as well as certain populations of stem cells and blood vessel cells.
Some studies have hinted that anosmia in COVID-19 differs from anosmia caused by other viral infections, including by other coronaviruses.

Are Treatments Available For Restoring These Senses
A lack of research means few established treatments exist. But one option is smell training, in which people sniff prescribed odours regularly to relearn them. Hopkins is working with a charity called AbScent in Andover, UK, to get the word out to the public about this training. There is evidence from before the pandemic that it can improve smell function in some people with such impairments, but it doesnt seem to work for everyone.

What If You Lose Your Smelling Senses Overnight
Tajudeen says that a sudden loss of smell can mean a viral condition is at play.
Usually when people have a cold, they have congestion and a runny nose, and they cant breathe through their nose, he says. 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.
While most cold viruses cause congestion, other viruses can actually affect the olfactory sensory neurons in the nose. These neurons detect and send odorant information to the central nervous system. When a virus attacks these neurons, it can trigger a sudden, complete loss of smell, a condition referred to anosmia.
This sudden smell loss usually happens after you experience a severe cold, once your other cold symptoms have cleared up. It can result in a loss of smell that lasts from 6 months to years in some instances, it may even be permanent. Additionally, patients may report phantom smells such as smelling smoke or gasoline when not present or having altered smells.
Look Out For These 5 Signs
“COVID-19 symptoms have seen some variation since the beginning of the pandemic. But, since the beginning five symptoms have remained very prominent- fever, cough, shortness of breath, fatigue, or body aches,” Dr. Jagdish Khubchandani, MBBS, Ph.D. Professor of Public Health New Mexico State University explains. “Interestingly, many of these symptoms are also some of the most common symptoms seen in survivors of an infection .” rel=”nofollow”> AMA publications. Other frequent symptoms are sore throat, runny nose, chest/nasal congestion, and sometimes nausea, vomiting and diarrhea.”

I Lost My Sense Of Smell: Do I Have Covid
Understanding the differences between common smell loss and COVID-19 symptoms
Do I have COVID-19 or is it something else? This question has probably crossed your mind a time or two or maybe even 20. COVID-19 symptoms can be so similar to other conditions, its not unusual to search your symptoms to see if you need to be tested.
One COVID-19 symptom thats frequently Googled: smell loss.
There are actually a variety of reasons other than COVID-19 why someone may lose their sense of smell, says Bobby Tajudeen, MD, director of rhinology, sinus surgery and skull base surgery at Rush University Medical Center. It can be due to nasal or sinus inflammation, or other viral infections distinct from COVID-19. And it can even occur as a result of some neurodegenerative diseases, like Alzheimers or dementia , or vitamin deficiencies. Rarely tumors can present with smell loss.
So how do you know if its COVID-19 or something else thats keeping you from enjoying the fragrant scent of your Christmas tree or the aroma of freshly baked holiday treats? And when should you see a specialist for smell loss?
Tajudeen says that while smell loss from congestion or common viral infections and COVID-19-related smell loss may feel the same on the surface, whats happening internally and how the symptoms present themselves is actually very different.
Smell And Taste Loss After Covid: Should You Be Worried
Since the earliest days of the pandemic, doctors treating people with COVID-19 noticed that a sudden loss of smell was a hallmark of the illness. As the vast majority of our sense of taste derives from our sense of smell, these COVID-19 patients also may have experienced a loss of taste as well.
After recovering from COVID-19, many patients fail to recover their sense of smell right away, and some may worry the situation could be permanent.
A recent study has encouraging news for these patients. The results showed that nearly all patients who lost their sense of smell after having COVID-19 regained the ability.

Effects Of Losing Your Ability To Smell
For those that do lose their sense of smell for a prolonged period, there can be concerns that extend beyond the pleasure of tasting ones food.
A lot of people dont realize how much they miss their sense of smell until it is gone. For example, not being unable to smell something burning can be a health hazard, says Brian DAnza, MD, a UH rhinologist and sinus surgeon.
Is The Omicrom Variant Milder Than Delta
Although it is too early to tell for certain, there is evidence that the Omicron Covid-19 variant presents milder symptoms than the Delta variant which is the most common mutation in the UK.
WHO chief Tedros Adhanom Ghebreyesus told reporters on Wednesday, There is also some evidence that Omicron causes milder disease than Delta.
He added that, despite this, Omicron suggests an increased risk of infection.
This means that youre more likely to get Omicron than other variants, but it may not be as severe.
In fact, Omnicron is believed to be multiplying at a rate 70 times faster than Delta.
A report released December 4 from doctors at the Steve Biko/Tshwane District Hospital Complex in Pretoria seems to confirm the theory that Omicron is not as severe as other variants.
Dr. Fareed Abdullah, director of the Office of AIDS and TB Research at the South African Medical Research Council, looked at the 42 people in the hospital who had tested positive for the Omicron variant of coronavirus.
Of those, 70% did not need a ventilator. Of the 13 people on supplemental oxygen, four were receiving it for a non-Covid-19 medical condition.
Dr Abdullah wrote in the report that this differed dramatically from earlier in the pandemic.
During previous waves, the Covid-19 ward was recognisable by the majority of patients being on some form of oxygen supplementation with the incessant sound of high flow nasal oxygen machines, or beeping ventilator alarms, he wrote.

Patients Are Devising Their Own Home Cures To Revive Their Sense Of Smell And Taste
Ever since COVID-19 led to his own long-haul battle with smell and taste loss, Todd Kennedy has seen surprising results with a trick he made up himself: I went to a Starbucks and got an iced chai latte with hazelnut, which is my favorite drink there, and I took a sip of that and put my mask back on. I realized that when Im breathing into my mask after taking a sip, I felt like I could taste it.
Meanwhile, all kinds of fad treatments have popped up on the internet. One is the burnt orange hack, which suggests roasting an orange over a flame until its charred on the outside, then cutting it open, mixing the fruit with brown sugar, and eating it. Raves about the trick abound on TikTok, but does it actually work?
We dont have research to say this is an effective strategy, says Linsenmeyer, but she adds that if someone feels a certain food is helping bring back taste or smell certain Sichuan dishes, for example, made a difference for one New York Times restaurant critic its worth a shot. If it works for people to eat a curry, say, and they can taste those flavors, it cant hurt to try.

Smell Or Taste Loss Can Pose Certain Health Risks
Not being able to smell can be frustrating, but the symptom can also bring with it more serious risks. If you have loss of smell, youre unable to smell rancid food or a gas leak, says Del Signore. Its an everyday safety issue.
The loss can also take a psychological and emotional toll. Some people become depressed, and people can get despondent if theyre with friends or family and they cant taste the food, says Doty. People dont relate to their problem, so they learn to shut up about it. It becomes debilitating, and they change their social behaviors, so they become very insular.
Patients who are struggling with anosmia should seek medical attention, even if theyve since recovered from COVID-19 or are not even sure the virus was the cause.
/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.

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 well learn more about that as we follow these patients over time.
Time Of Onset Of Symptoms
The articles reviewed reported conflicting results regarding the time of onset of symptoms of loss of smell and/or taste in patients diagnosed with COVID-19. Many studies, however, reported that the onset of anosmia and ageusia occurred 4 to 5 days after the appearance of other symptoms of the infection . Analysis of the prevalence of the appearance of changes in smell and/or taste before, simultaneously with or after other symptoms as reported in these articles found that the prevalence of such symptoms emerging prior to other symptoms varied between 13% and 73% in patients the prevalence of such symptoms emerging at the same time as other symptoms, varied from 13.5% to 38.4% and that of such symptoms appearing after other symptoms from 27% to 48.6% .

Symptoms Most Covid Patients Have Now
To date there have been794,000 deaths from COVID in the U.S and as we continue to learn about the virus, one thing is for certain: It affects everyone differently. That said, there are a few common signs that indicate you have COVID and according to Dr. Justin Johnson, Emergency Medicine and Critical Care with Mercy Hospital, “symptoms include cough, fever, shortness of breath and to a lesser extent loss of taste/smell and loss of endurance.” The ZOE COVID Study, which is the world’s longest of study COVID-19 and is led by Professor Tim Spector, a professor of genetic epidemiology at King’s College London, lists other symptoms to be aware of.

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.

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.
