Parosmia is a potential symptom of long-haul COVID-19. It’s believed to develop from damage that occurs to the tissues involved in smell during infection with the coronavirus SARS-CoV-2. For example, to someone with parosmia, a flower may smell like rotting meat.
Some people may have difficulty identifying specific smells, or notice no changes with odor intensity. Others may experience changes to smells that were once pleasant or normal, and find them intolerable. Because smell is directly related to taste, some people may also find previously enjoyable meals repulsive. If you’ve lost your sense of smell and can’t regain it with at-home treatment, talk to your doctor. They may recommend medical treatments to use alone or in combination with at-home smell therapy.
Smell training
For some people, it may be the aroma of fresh cut grass or blooming flowers. For others, a newborn baby’s skin, or the scent of bread baking can bring feelings of calm and serenity. Open the windows or use a fan to help dissipate scents that trigger parosmia. Focus on blander food items, such as oatmeal or steamed vegetables, which may be less likely to trigger parosmia. However, none of the currently authorized COVID-19 vaccines contain live virus. Instead, the vaccines provide instructions to your cells on how to make a single viral protein called spike protein.
It is used as a nasya, or nasal passage treatment for restoring sense of smell by Ayurvedic practitioners. If you are a smoker, your parosmia may disappear with time. But, parosmia is connected to the brain, so there is the possibility that it may ultimately stay. For example, toast may still smell like rotting meat, but it may not happen every time you smell toast. On the other hand, you may unfortunately be stuck with parosmia for the rest of your life or until a cure is found. URTIs like sinusitis, common cold, laryngitis, bronchitis, pharyngitis, sore throat, pertussis, and tonsillitis.
Who’s at risk for getting parosmia after COVID-19?
Another adult, a 32-year-old female, reported smelling onions after 72 days. In a 2005 study of 56 people with parosmia, just over 40 percent of them had an upper respiratory infection they believed was connected to the onset of the condition. Traumatic brain injury has been linked to olfactory damage. While the duration and severity of the damage depends on the injury, a review of medical literature indicated that symptoms of parosmia after a TBI are not uncommon. It often fades gradually over time, without treatment or intervention.
Scents that you used to find pleasant may now become overpowering and unbearable. If you try to eat food that smells bad to you, you may feel nauseous or sick while you’re eating. People experience a wide range of parosmia for an array of different reasons.

Your doctor will also look for other symptoms, such as tremors, which might indicate a neurological condition like Parkinson’s disease. Unfortunately, as we get older, our brains change for both good and bad. Those changes can affect the olfactory lobe of the brain to the point where parosmia can take place. A number of neurological disorders like Alzheimer’s disease and Parkinson’s can cause the brain to process things in different ways than they should, including smells. Our sense of smell is something we don’t really pay any attention to—unless something goes wrong. The truth of the matter is that it is closely tied to the other senses, especially our sense of taste.

For example, something that once smelled pleasant may smell bad or rotten to a person with parosmia. Additionally, some people may also experience parosmia after having COVID-19.

A common test for parosmia involves a small booklet of “scratch and sniff” beads that you respond to under a doctor’s observation. Parosmia can be diagnosed by an otolaryngologist, also known as an ear-nose-throat doctor, or ENT. The doctor may present different substances to you and ask you to describe their scent and rank their quality. Most cases of parosmia become apparent after you recover from an infection.
