When to see a doctor

By Mayo Clinic Staff

Loss of smell caused by colds, allergies or sinus infections usually clears up on its own after a few days. If this doesn't happen, consult your doctor so that he or she can rule out more-serious conditions.

Additionally, loss of smell can sometimes be treated, depending on the cause. Your doctor may give you an antibiotic to treat a bacterial infection, or remove anything blocking your nasal passage. But in some cases, loss of smell can be permanent.
