Hyperhidrosis or excessive sweating is seen very often by podiatrists. It is more common in men than in women and more common in young adults.According to the International Hyperhidrosis Society, 3 percent of the population suffers from hyperhidrosis. There is no etiology of excessive sweating but it seems to be an inherited problem. Most people sweat when it’s hot out, but people with hyperhidrosis sweat excessively almost all the time. Due to excessive sweating, feet can appear whitish, with moist appearance. Foot infections can occur as constant moistness can break skin easily allowing bacteria to penetrate easily. Foot odor is another symptom of hyperhidrosis.
Home care remedies include, good foot hygiene, washing the feet daily with antibacterial soap, drying the feet thoroughly. Corn starch, foot powder and anti-fungal powder can also cause decrease in sweating. Avoid cotton socks since they absorb moisture. Over the counter antiperspirants can be applied directly to the feet
A technique called iontophoresis, which uses water to conduct a mild electrical current through the skin, has been found helpful for people with sweaty feet. Another treatment option for heavy sweating is injections of botulinum toxin A (Botox), the same medicine used for wrinkles. Botox is FDA-approved for treating excessive sweating of the underarms, but some doctors may also use it on the palms of the hands and soles of the feet. Botox works by preventing the release of a chemical that signals the sweat glands to activate. The results can last for 9 months-1year.
Severe cases of sweaty feet may be treated with a surgical procedure called a sympathectomy where small incisions are made and nerves that normally activate sweat glands are cut. This procedure is very effective but is used as a last resort. If you are experiencing this problem, please contact our doctors by calling 732-297-9535
