What’s Causing My Loss of Smell and Taste?

Common Causes of Loss Of Smell and Taste

* Sinus Infection: One of the most common causes of a loss of smell and taste is a sinus infection. When the sinuses become inflamed or infected the congestion and swelling in the nasal passages will block the flow of air to the olfactory receptors, compromising their ability to pick up on scents.

* COVID-19: Loss of smell and taste are two common symptoms of COVID-19, especially in mild or moderate cases. The virus can damage the cells that support your sense of smell and taste, leading to a temporary loss that usually comes back within a few months.

* Allergies: Allergies such as hay fever can block airflow through the nasal passages, leading to a loss of smell and taste. This can be especially true during allergy season when allergens like pollen are at their peak.

* Dry Air: Dry air such as on airplanes, in heated indoor areas or from medication with anticholenergic effects like anti-histamines can also lead to a temporary loss of smell and taste.

* Head Injuries: Injuries to the face or head can damage the olfactory nerve, leading to a loss of smell and taste.

* Certain Medications: Some medications like antibiotics, chemotherapy drugs, anti-inflammatory drugs like aspirin and ibuprofen, and oral steroids can have side effects which include a loss of smell and taste.

* Chronic Infections: Some chronic conditions such as diabetes, HIV/AIDS, and other neurological disorders can lead to a loss of smell and taste as well as other symptoms.
