Hypohidrosis or Anhidrosis

Impaired sweating, either hypohidrosis or anhidrosis, usually presents in childhood or adolescence, and has been attributed to selective peripheral nerve damage or to intracytoplasmic lipid deposits in the small blood vessels surrounding sweat glands.1-2 This may result in dry skin and heat and exercise intolerance. In approximately 40% of Fabry disease patients, production of tears and saliva is also reduced.3
