Excessive sweating can have a number of underlying causes, and while it often doesn’t mean anything is seriously wrong, it can have a significant impact both personally and socially. Find more information about hyperhidrosis and its causes below, and the treatments available at The Dermatology Clinic London.
There are two main types of hyperhidrosis.
This type of hyperhidrosis involves excessive sweating of the armpits, palms, soles of the feet, scalp or face. It is unclear what causes focal hyperhidrosis, but it is not a symptom of an underlying health condition. Triggers include:
Focal hyperhidrosis can be genetic and it affects men and women equally. Though it can affect people at any age, symptoms most commonly begin before the age of 25.
Unlike focal hyperhidrosis, this type of excessive sweating can be caused by an underlying health condition. You may experience generalised hyperhidrosis if you suffer from the following:
Sometimes, taking certain medications can also lead to excessive sweating.
We see many cases of hyperhidrosis, so there’s no need to be embarrassed when you discuss your problem. Depending on the type of hyperhidrosis, we may ask about your medical history and order medical tests before going ahead with treatment. The Dermatology Clinic offers numerous treatment options that have proved highly effective in putting a stop to excessive sweating.
If you’ve been dealing with hyperhidrosis for a while, you’ve probably tried over the counter antiperspirants, but found that these don’t work. Our consultants may prescribe a clinical strength product to block the sweat glands and prevent excessive sweat. If your skin is prone to irritation, we’ll prescribe treatment to help control this.
A popular treatment for hyperhidrosis is Botox. This uses a weakened version of botulinum toxin A, which is gently injected into the affected area (usually the underarms). The toxin will block the chemical that activates the sweat glands, enabling you to stay dry. You’ll start to see results in around five days and the treatment is effective for up to six months.
Some cases of hyperhidrosis respond well to a type of medication called anticholinergics. Side effects are common with these drugs and will be discussed with you before prescription.
If your sweating is localised to your hands or feet, an effective option could be iontophoresis. This process involves sending a low-voltage electric current to your skin to deactivate the sweat glands. Our dermatologists recommend two to three sessions a week until the sweating stops completely.
As a last resort, we can recommend surgery only if other treatments haven’t been as successful as hoped. Surgery aims to either stop the nerves that activate sweating or remove the sweat glands altogether.
