Plantar Hyperhidrosis, severe sweating of the feet, usually occurs in conjunction with Palmar Hyperhidrosis, hand sweating, as a result of an overactive sympathetic nervous system. People with Plantar Hyperhidrosis complain of bad foot odor. The most common problems with Plantar Hyperhidrosis are athlete’s feet, blisters, infection and rotting of socks. Regular shoes must be purchased more frequently, because moisture ruins the shoes. It is almost impossible to wear sandals with this condition. The sweat makes the feet slip and slide right out of the shoes! It can be uncomfortable and dangerous to drive, when the feet are sweating, profusely. The right foot can slip off the accelerator or brake pedal, resulting in the very real possibility of losing control and causing an accident.
Anyone with Plantar Hyperhidrosis who goes through an exercise, dance, or martial arts program with bare feet will leave wet spots on the floor. This will be embarrassing, but, more importantly, can be hazardous for the participant and others engaging in the activity. Falls could occur, as a result of the wet spots.
Most of the patients who have sweaty hands will also have sweaty feet. When Thoracic Sympathectomy is performed to alleviate Palmar Hyperhidrosis(hand sweating), the results for Plantar Hyperhidrosis (sweating feet) vary. Some patients will experience reduction or cessation of foot sweating and some may see lesser results. About 60 to 70% of the patients who suffer from Plantar Hyperhidrosis will see improvement after the procedure is performed.
