Hyperhidrosis
The excessive secretion of sweat from the eccrine glands, hyperhidrosis usually occurs in the axillae (typically after puberty) and on the palms and soles (commonly starting during infancy or childhood).
Causes
Possible causes of hyperhidrosis include the following:
Genetic factors may contribute to the development of hyperhidrosis and, in susceptible individuals, emotional stress appears to be the most common cause. Increased central nervous system (CNS) impulses may provoke excessive release of acetylcholine, producing a heightened sweat response.
Exercise and a hot climate can cause profuse sweating in these patients.
Certain drugs, such as antipyretics, emetics, meperidine, and anticholin-esterase, can increase sweating.
In addition, hyperhidrosis may occur as a clinical manifestation of an underlying disorder. Infections and
chronic diseases, such as tuberculosis, malaria, and lymphoma, may cause excessive nighttime sweating. Diabetic patients commonly demonstrate hyperhidrosis during a hypoglycemic crisis.
