Anosmia is the inability to perceive smell (medically termed olfaction).
When the loss of smell is not complete, the disorder is called hyposmia.
Some people are anosmic for one specific odor; this is called “specific anosmia”.
Specific anosmia is normally genetically based.
Most patients with anosmia complain of losing the sense of taste (ageusia) and of not enjoying food.
They can sense salty, sweet, sour, and bitter substances but flavor bias which is a function of smell is not possible.
Smell is sensed by a special lining in the posterior portion of the nose called the olfactory epithelium.
Signals are carried from this lining via nerves to the brain.
Any factors that block the smell from reaching this lining or induce injury may cause anosmia.
Injury to nerves that bring the signals or the part of the brain that senses smell can lead to anosmia.
Anosmia may be part of normal aging.
The most frequent causes of anosmia are respiratory infections, sinusitis, and head trauma.
Anosmia or losing the ability to smell is quite a frequent problem which a patient has at one point or the other.
Anosmia can be incomplete or complete but it is very infrequent that someone has total loss of the capability to smell.

This may make the person with permanent anosmia depressed.
The patient may soon lose interest in eating foods as he or she is not able to enjoy food that normal people do due to Anosmia or ...
