Hyperhidrosis is the medical term for excess perspiration. This commonly affects the hands and soles of the feet. The clinical appearance is sometimes a general redness of the feet with moist skin that is cool to touch. It is sometimes in response to mental or emotional stress. This can cause burning, itching and blister formation. The moist environment can lead to a fungal infection of the skin if not treated. When there is a bad odor associated with this it is called Bromhidrosis. Bromhidrosis occurs due to the normal bacteria that harbors on your skin producing biochemical biproducts.
Treatment of both Hyperhidrosis and Bromhidrosis is usually by having good hygiene and by managing the amount of sweat produced. Your feet should be washed daily with soap and water, then dried thoroughly between the toes to remove the dead skin. Socks and shoes should be kept clean and not shared between individuals. Avoid wearing dark synthetic socks, pantyhose, and occlusive shoes like vinyl. Absorbent powders and talcs may be used to reduce friction. Perspiration reduction can be achieved with topical antiperspirants. Caffiene, teas, and sodapop stimulates sweat production and should be avoided as well. Since sweat production is related to stress, reduction in stress and relaxation techniques may be helpful. See your podiatrist for further advice as there are many treatment options available.
