The sense of smell is important in taste perception. About 80% of the flavor we perceive from food is a function of the ability to smell. For this reason, people with anosmia usually lose interest in food.
Anosmia is the medical term for loss of sense of smell. It could be congenital, where a person is born without a sense of smell, or acquired as a result of a nasal condition or brain injury. Anosmia could also occur in the normal process of aging.
Some of the causes of anosmia include cold, sinusitis, crooked nose, some medications, diabetes, long term alcohol misuse, head injury etc. Treatment of anosmia is dependent on the cause. This determines if the condition can be cured or not.
People with anosmia have to take special precautions, as they are unable to smell fires, leaking gas, stale food and other substances which could be dangerous. However, those with a partial loss of the sense of smell could cope a little bit better than having absolutely no sense of smell. The reduced ability to smell is called "hyposmia". #25DoctorsFact #Facts #Fact #smell #didyouknow
