Hyperhidrosis Symptoms

The defining symptom of hyperhidrosis is excessive sweating. While the definition of “excessive” is somewhat subjective, people with hyperhidrosis can readily separate sweating that interferes with daily life from the usual perspiration during exercise or on hot days.

Palmar hyperhidrosis occurs on the palms of the hands. Plantar hyperhidrosis describes excessive sweating of the feet, while axillary hyperhidrosis affects the area beneath the arms. Some people with hyperhidrosis find that more than one part of the body sweats excessively; others perspire everywhere, although this generalized hyperhidrosis is rare.

The disorder can have a profound impact on quality of life. Affected individuals may become reluctant to shake hands, handle objects that show moisture, or touch other people. Severe cases of generalized hyperhidrosis can mean repeated changes of clothing or footwear.

Secondary health concerns also arise in severe cases. Constantly damp skin is prone to infections and chafing. Hyperhidrosis can cause dehydration, especially if the affected individual lives in a hot climate.
