Hyperhidrosis is a disorder that causes excessive sweating. This sweating can occur in unusual circumstances, such as in cool weather, or without any triggers. It can also be caused by other conditions, such as menopause or an overactive thyroid. Hyperhidrosis can be uncomfortable. However, several treatment options can provide some relief. Botox injections use botulinum toxin to block the nerve signals responsible for sweating, preventing the sweat glands from producing too much sweat.
