Sweaty Feet (Hyperhidrosis)
Hyperhidrosis, or excessive sweating, can be localized to one area or it may be generalized. In the localized type, the most common sites are the palms and soles of the feet. The cause of the excessive sweating is not well understood. There is an emotional component to it in some but not all cases. The excessive moisture contributes to athlete’s foot and plantar wart infections. There are no good oral medications for the control of hyperhidrosis. Topical antiperspirants are of little value. A prescription topical medication called “Dry sol” is of some value. This medication works best if applied to the feet before going bed, then wrapping the feet in plastic wrap and wearing socks. This should be done three to four nights in a row. Although this is not a cure for the problem, it does provide temporary relief and is useful as part of the treatment plan for athlete’s foot and plantar warts in patients who suffer from hyperhidrosis.
