What is Hyperhidrosis?
Hyperhidrosis refers to excessive sweating that can cause anxiety, embarrassment, and may interfere with daily activities.
Hyperhidrosis may run in families and often starts in childhood or teenage years. Less commonly, it may be caused by certain medical conditions or medications.
It can affect the entire body (generalised) or only specific areas (localised). Localised hyperhidrosis is the most common type and usually occurs over the palms, soles, and armpits, while less commonly, the face and scalp may be affected.
What are the treatment options for hyperhidrosis?
Topical antiperspirants are the simplest treatment, usually applied nightly. The antiperspirant is pulled into the sweat glands, plugging them temporarily. Common side effects include burning and irritation.
Botulinum toxin is mainly used for underarm sweating, but can also treat palms and soles. Multiple tiny injections block the chemical that stimulates sweat glands, and the reduction in sweating typically lasts 4–6 months.
Oral medications may be prescribed for generalised hyperhidrosis. They temporarily stop sweat gland activity, but may cause side effects such as dry eyes and dry mouth.
