How many people have anosmia

Fortunately, for the vast majority 95 percent , sense of smell returns within a few weeks. In addition, we will be starting several treatment trials. It is too early in the pandemic to say with certainty how effective these treatments are. We do believe that starting treatment as early as possible is most likely to be helpful. Sense of smell is important for defense and protection i.

Doctors may recommend corticosteroid drugs to manage anosmia, taken either into the nose or by mouth. Researchers have only shown that topical intranasal steroids are effective in allergic rhinitis, especially when a person takes them with intranasal antihistamine.

Oral corticosteroids can be effective for anosmia, although the dose and duration are still controversial. Doctors may find it challenging to predict whether surgical methods can help with anosmia. However, endoscopic sinus surgery might improve anosmia in some people. Some cases of anosmia may also resolve spontaneously without treatment. Some people living with anosmia report they have difficulty finding and receiving appropriate care for their condition.

Part of the issue is that some people living with anosmia have difficulty detecting, identifying, and distinguishing the condition. People living with anosmia may experience a lower quality of life. Mealtime may also be less enjoyable when a person cannot smell their food. Anosmia can also be dangerous. The ability to smell spoiled food or poisonous liquids can prevent a person from accidentally ingesting toxins.

The novel coronavirus responsible for the COVID pandemic causes reduction of smell and taste in many patients. These symptoms occur early in the disease and may sometimes be the only recognizable symptom in people with the SARS-CoV-2 virus.

However, further studies throughout the pandemic reported higher rates of anosmia. A hypothesis for why some people with a SARS-CoV-2 infection develop anosmia is genetic differences in the ability of the virus to attach to receptors in the nasal cavity. This may dictate the infectivity and spreading of the virus. Researchers need to conduct further studies to investigate these findings. If research can support this hypothesis, it may help clinicians better describe which populations are more at risk of developing COVID, and may help healthcare experts manage the pandemic more effectively.

People with a SARS-CoV-2 infection typically regain their sense of taste and smell after several days or weeks, but for some, it can take much longer than that. Anyone who recognizes a loss of or change in their sense of smell should contact a doctor.

Depending on the cause of anosmia, doctors may select different treatments. These may include cell therapy, drugs, smell training, or surgery. If a person thinks they may have been exposed to the novel coronavirus or are experiencing symptoms of COVID, they should self-quarantine and call their local public health office for instructions. Although losing the sense of smell, or developing anosmia, does not appear to be life threatening, the complications can be dangerous.

Smell allows people to recognize a dangerous environment or spoiled food, and people living with anosmia lose this ability. PubMed Article Google Scholar.

Pence, T. Boesveldt, S. Senses 42 , — Vaira, L. Download references. News 11 NOV Career Guide 10 NOV One year, my dad came down with a terrible cold and a very high fever. By Christmas that year, we were all gathered in the kitchen as my dad cooked a big family dinner. My cousin, who was standing near the stove, said she smelled gas.

It turned out one of the burners was no longer lit and gas was escaping quickly through the house. Or how about a new parent who can no longer smell their new baby?

When the SARS-CoV-2 virus arrived last year and became a global pandemic, many people who were infected reported losing their sense of smell. It was such a common complaint that it was added to the list of symptoms used by the CDC to diagnose the disease. One of the reasons for the wide variation in the estimates of COVIDassociated anosmia is the way that smell is measured. Using subjective, patient-based questionnaires, interviews and health records can be unreliable. But gathering more reliable objective measures requires testing patients in person by having them smell actual smells.

These tests are hard to coordinate during a pandemic that recommends social distancing. Louis, Missouri.
