What Is Anosmia? Know Causes, Symptoms, Treatment and More

Have you ever felt that you have lost your sense of smell for some time? It is called Anosmia in the medical dictionary. This is a health condition where the person suffers temporary or permanent smell loss. As per the data, one in 10,000 people, is born with this condition, also called congenital anosmia where they are born with no sense of smell. Almost all of us suffer from this condition at some point where our nose couldn’t smell anything due to congested nostrils. While this is for time-being, congenital anosmia is a life-long issue.

Congenital: This anosmia happens in one out of 10,000 adults where they are born with this condition.
