What causes smell disorders?

Smell disorders have many causes, some clearer than others. Most people who develop a smell disorder have recently experienced an illness or an injury. Common triggers are upper respiratory infections and head injuries. In some patients, the exact cause for decreased smell remains unknown, even after more serious causes are ruled out.

Among other causes of smell disorders are polyps in the nasal cavities, sinus infections, hormonal disturbances, or dental problems. Exposure to certain chemicals, such as insecticides and solvents, and some medicines have also been associated with smell disorders. People with head and neck cancers who receive radiation treatment are also among those who experience problems with their sense of smell.

Comment from: smellntaste, 55-64 Female (Patient) Published: September 15

My taste and smell distortion started at age 25. One day like a switch turned on, I noticed things smelled and tasted awful, kind of chemical-like. It stayed that way all day, however the next day I was back to normal after sleeping all night. I found that whenever this happened, even a short nap would usually bring my taste and smell back to normal. I had a CT scan in 1987 to see if there was a mass but nothing was found. My doctor and neurologist were baffled. Years later I found that if I bent over and let the blood rush to my head that sometimes got me back to normal. However, those two solutions are difficult to do in a restaurant when you really want to enjoy your meal! Even though this happens to me at any time of year, I noticed frequency (several times a day) in the months of September and March.
