Hyperhidrosis is characterized by the presence of increased perspiration or sweating that is more than that needed for the regulation of temperature of the body. Hyperhidrosis can be classified into two types: Generalized and Localized. Due to the presence of large number of sweat glands in the region of hands, feet, armpits and the groin, they are most often affected by localized Hyperhidrosis, also referred to as primary Hyperhidrosis. In generalized Hyperhidrosis, also referred to as secondary Hyperhidrosis, increased perspiration occurs in the whole body and is usually the result of an underlying medical problem. Excessive sweating of the soles and palms is known as palmoplantar Hyperhidrosis and excessive sweating of the underarms is known as axillary Hyperhidrosis. Hyperhidrosis usually happens in healthy individuals. Its treatment ranges from over-the-counter antiperspirants to prescription antiperspirants. Other treatment methods that are used for Hyperhidrosis are iontophoresis, oral anticholinergic drugs, destruction of sweat glands using microwave radiation, botox and surgery.
