Hyperhidrosis is excessive sweating which is not caused by physical exertion nor high temperature. People with this common condition may suffer from anxiety or embarrassment since their clothes often get soaked with sweat.
Generally, there are two types of hyperhidrosis: primary focal and secondary. Those with primary focal hyperhidrosis, the most common type, have overactive sweat gland nerves. It has no medical cause and it may be hereditary; it usually involves the face, palms, and soles. Secondary hyperhidrosis is less common and is attributed to a medical condition such as diabetes, menopause, thyroid problems, heart conditions, and infections.
