Excessive sweating happens when a person sweats more than is necessary. Yes, it’s necessary to sweat. Sweating cools the body, which prevents us from overheating. People who have hyperhidrosis, however, sweat when the body does not need cooling.
Many people who have hyperhidrosis sweat from one or two areas of the body. Most often, they sweat from their palms, feet, underarms, or head. While the rest of the body remains dry, one or two areas may drip with sweat.
This excessive sweating can interfere with everyday activities. Hands can be so sweaty that it becomes difficult to turn a doorknob or use a computer. Sweat from the underarms often soaks through clothes, causing obvious sweat marks. Because the skin is often wet, skin infections can develop.
Treatment for localized hyperhidrosis involve injecting neuromodulators, such as Botox, ● ● Xeomin, or Dysport into the affected area. The neuromodulators then block the nerves that supply the eccrine glands, preventing the production of sweat. Topical anesthetics can be applied prior to treatment to reduce pain and discomfort. Reduced perspiration can be noted within 2-4 days, with full effect occurring within 2 weeks.
