hyperhidrosis (excessive sweating)

Excessive sweating, also known as hyperhidrosis, is a common medical condition that can significantly impact daily life, confidence, and comfort. If you find that sweating interferes with your work, social activities, or wellbeing, effective help is available.

Hyperhidrosis is caused by overactivity of the nerves that stimulate the sweat glands, rather than a problem with the glands themselves. It is not related to having more sweat glands than usual.

Could it be something else?

Before diagnosing hyperhidrosis, it’s important to rule out other causes of excessive sweating, such as thyroid problems, infections, hormonal changes (like menopause), or certain medications. A careful history and examination help guide the right investigations if needed.

treatment options

There are a range of safe and effective treatments for hyperhidrosis. The best approach depends on the area affected, severity, and your individual needs.

First Line Treatments

Specialised antiperspirants containing aluminium chloride are often the first step. These are applied at night and may cause mild skin irritation.

Other Treatment Options

Prescription topical medications designed to reduce sweating
Oral medications that help block the chemical signals to sweat glands (these may have side effects and are not suitable for everyone)
Botulinum toxin injections, particularly effective for underarm and hand sweating (results are temporary and repeat treatments are needed)
Iontophoresis (a device-based treatment for hands and feet, involving mild electrical currents)
In rare, severe cases, surgical procedures may be considered
