Hyperhidrosis is a condition when there is abnormally excessive sweating that is not related to heat or exercise . For many people, excessive sweating is simply caused by sweat glands that are slightly overactive. However, overactive sweat glands are just one of the underlying causes. Some other causes of hyperhidrosis are diabetes; pregnancy; cancer; heart disease; side effects from antidepressants, analgesic painkillers, and cardiovascular drugs; hormones during adolescence; obesity; alcohol abuse; Parkinson’s Disease; infection; anxiety and stress. Hyperhidrosis usually affects the hands, feet, underarms or face and causes at least one episode a week, during waking hours. The sweating usually occurs on both sides of the body. If heavy sweating is accompanied by lightheadedness, chest pain or nausea, this is serious and needs medical attention immediately.
