Alterations in the perception of odors and flavors are the types of disorders seen the most and they prevent proper communication with our environment, but they do not endanger the lives of those who suffer them.

Some people are born with chemosensory alterations, although most taste and smell afflictions are due to diseases in the respiratory pathways, hormonal disorders, odontology problems or head injuries. Other disorders are caused by exposure to chemical substances or due to the use of medication, as well as tobacco and alcohol consumption.

A few diseases that affect the sense of taste are:
Ageusia: loss or reduced capacity of the sense of taste. It is due to trauma suffered by the tongue, like burns or facial paralysis.
