noun, plural: anhidroses
A condition characterized by a diminished ability to sweat in response to an appropriate stimuli
Sweating or hidrosis is an essential physiological mechanism of the body to regulate body temperature relative to its surroundings. It also occurs when the body is under an emotional stress or intense physical activity regardless of the ambient temperature. But primarily sweating is the way of the body to regulate and keep up a healthy body temperature. Failure to do so can be a threat to life. For instance, failure of the body to cool down can lead to overheating and eventually to heat stroke, which is fatal. There are cases when the body is totally unable to produce sweat and the condition is called anhidrosis. There are types of anhidrosis wherein it is regarded as mild and thereby also called as hypohidrosis.
The diminished ability to sweat even in the presence of an appropriate stimulus is referred to as hypohidrosis. It can be caused by a nerve damage, clogged ducts, skin injuries, other ill conditions such as diarrhea, vomiting, and fever, and medication (i.e. as a side effect of certain drugs, e.g. oxybutynin, tricyclic antidepressants, and trihexphenidyl).1
