Hyperhidrosis, the medical term for excessive sweating, affects around 3% of the general population. Men and women are equally affected, with the most common occurrence in individuals aged 25 to 64 years. Because 30 – 50% of sufferers have another family member afflicted with the condition, it’s thought to imply a genetic predisposition.
Most individuals with hyperhidrosis suffer with sweaty palms, but feet, underarms and the face may also be affected. Even when the temperature is cool or the individual is at rest, sweating may occur. This can lead to emotional upset and have a serious negative impact on daily life.
It’s thought that overactivity of the sympathetic nervous system is the cause. Other factors including anxiety, certain foods and drinks as well as smells can trigger a response.
Hyperhidrosis Treatment
A number of treatments are available such as:
- Antiperspirants containing high concentrations of aluminum chloride hexahydrate and are the most commonly used products in the treatment of underarm sweating.
- Medication. Anticholinergics which help to prevent the stimulation of sweat glands can be effective in some patients, but they do come with side effects including dry mouth, dizziness, and urinary problems. Beta-blockers or benzodiazepines may help if anxiety is an issue.
- Iontophoresis. This FDA-approved procedure uses electricity to temporarily turn off the sweat gland and is most effective in the treatment of hands and feet.
- Botox. Botulinum toxin is FDA approved for the treatment of severe underarm sweating. It works by temporarily blocking the nerves that stimulate sweating. It does come with side effects.
