Sweating - absent - Overview

Alternative Names

Decreased sweating; Anhidrosis

Definition of Sweating - absent:

An abnormal lack of sweat in response to heat may be harmful, because sweating allows heat to be released from the body. The medical term for absent sweating is anhidrosis.

Considerations:

Anhidrosis sometimes goes unrecognized until a substantial amount of heat or exertion fails to cause sweating.

Overall lack of sweating can be life threatening because the body will overheat. If the lack of sweating happens in a small area only, it is usually not as dangerous.

Common Causes:

  • Neurologic disorders such as Guillain-Barre syndrome
  • Skin diseases that block sweat glands
  • Congenital disorders including as ectodermal dysplasia
  • Some drugs
  • Trauma to sweat glands
  • Burns
  • Dehydration
