Typical regions of excessive sweating include the hand palms, underarms, the sole of the foot, and sometimes groin, face, and scalp. Indeed, profuse sweating is present mostly in the underarms, followed by the feet, palms and facial region. Sweating patterns of<unk>  are typically bilateral or symmetric and rarely occur in just one palm or one underarm. Night sweats or sweating while sleeping is also rare. The onset of<unk>  is usually before the age of 25 years. This is in contrast to generalized hyperhidrosis which tends to occur in an older age group. Evidence demonstrates that a positive family history is also present (see the Genetics part).
