Loss of Smell


What Causes Loss of Smell?

Anosmia occurs when the sinuses become swollen and inflamed. The most common causes include colds, flu, allergies, sinusitis and nonallergic rhinitis. Nasal obstructions such as polyps, tumors and other deformities can block the flow of air through the nose and lead to a loss of smell.

There are many other possible causes including Alzheimer’s disease, brain tumor, aneurysm, diabetes, cocaine use, chemical exposure, malnutrition, hormonal imbalances, medications, Parkinson’s disease, rhinoplasty, radiation therapy and old age, among others.

What Are the Symptoms of Loss of Smell?


How Is Loss of Smell Treated?

Treating anosmia depends on what is causing it. If a cold or allergies are to blame, treatment is unnecessary; your sense of smell should return in a few days as symptoms improve. If a polyp or other growth is blocking your nasal passages, surgery may be necessary.

For bacterial infections, antibiotics are prescribed. Other conditions may require more specialized medical treatment. Occasionally, the sense of smell returns automatically, without any type of treatment.
