Anosmia is a condition characterized by the loss or absence of the sense of smell. People with anosmia are unable to detect odors or have a reduced ability to smell. It can be a temporary or permanent condition and can occur due to various factors such as nasal congestion, sinus infections, head injuries, or neurodegenerative diseases. Anosmia can impact a person's quality of life as it affects their ability to appreciate flavors, detect dangers (such as gas leaks or spoiled food), and may also affect their sense of taste.
