The natural ability of the olfactory system to repair itself allows for some patients to regain the sense of smell after a respiratory infection-related loss or head injury.
This recovery can take over a year, and can be so gradual that people have difficulty recognizing the change.
How do you treat loss of smell?
Treatment. Doctors treat the cause of the anosmia. For example, people with sinus infections and irritation may be treated with steam inhalation, nasal sprays, antibiotics, and sometimes surgery. However, the sense of smell does not always return even after successful treatment of sinusitis.
Is loss of smell serious?
