Treating the cause of the problem may correct the lost sense of smell. Treatment can include:
- Antihistamines (if the condition is due to an allergy)
- Changes in medication
- Surgery to correct blockages
- Treatment of other disorders
Avoid using too many nasal decongestants, which can lead to repeated nasal congestion.
If you lose your sense of smell, you may have changes in taste. Adding highly seasoned foods to your diet can help stimulate the taste sensations that you still have.
Improve your safety at home by using smoke detectors and electric appliances instead of gas ones. You may not be able to smell gas if there is a leak. Or, install equipment that detects gas fumes in the home. People with smell loss should label when the food item was opened to prevent eating spoiled food.
There is no treatment for loss of smell due to aging.
If you have a loss of smell due to a recent upper respiratory infection, be patient. The sense of smell may return to normal without treatment.
