Many people, especially those who sweat frequently, may wish never to sweat again. Anhidrosis causes a partial or complete inability to sweat. Though this may seem ideal, it can be a serious condition. Sweating is an essential function that helps regulate body temperature. Without sweat, symptoms of heat stroke can develop. A person can be born with anhidrosis or develop it later in life.
The primary symptom of anhidrosis is a lack of sweating. A person can experience anhidrosis over their entire body, or it can affect small patches of skin. If a person only experiences anhidrosis in a single area, they may not realize they have the condition. Anhidrosis that affects the entire body may result in flushed or warm feelings even in moderate temperatures and can cause muscle cramps and weakness.
