Hyperhidrosis disorder is a condition that results in excessive sweating. Sweating is a natural response to certain conditions, such as warm weather, physical activity, stress, and feelings of fear or anger. With hyperhidrosis, you sweat more than usual for no apparent reason. The underlying cause depends on which type of hyperhidrosis you have. This sweating can occur in unusual situations, such as in cooler weather, or without any trigger at all.

Through a systematic evaluation of causes and triggers of hyperhidrosis, followed by a judicious, stepwise approach to treatment, many people with this annoying disorder can sometimes achieve good results and improved quality of life. The followings are various types of treatments:

• Over-the-counter antiperspirants containing a low dose of metal salt (usually aluminium) are usually tried first because they are readily available.
• Prescription-strength antiperspirants, which contain aluminium chloride hexahydrate.
• Iontophoresis: A device that passes ionized tap water through the skin using direct electricity.
• Oral medications, Anticholinergics reduce sweating.
• Botox: Botulinum toxin-A has been approved in the U.S. by the FDA for treating excessive axillary (underarm) sweating.
• Machines: Certain machines using microwave techniques or radiofrequency can be used for the treatment of hyperhidrosis.
• Surgery: A procedure called thoracic sympathectomy may be considered as a last resort.

Botox works by blocking the nerves responsible for activating your sweat glands. Normally, your nervous system activates your sweat glands when your body temperature rises. This is how your body automatically cools itself. In people with hyperhidrosis, however, the nerves that signal the sweat glands are overactive. When you receive Botox injections directly into the area of your body that commonly sweats, your overactive nerves are essentially paralyzed. When your nerves can’t signal your sweat glands, you don’t sweat. However, Botox only prevents sweating in the specific area where it’s injected. The injections are usually tolerable.
