Excessive sweating (hyperhidrosis) can be challenging to treat and it may take a while to find a treatment right for you. Doctors usually recommend starting with the least invasive treatment first, such as powerful antiperspirants. Lifestyle changes may also help, including: wearing loose and light clothes; avoiding triggers, such as alcohol and spicy foods, that could make your sweating worse and wearing black or white clothes to help minimise the signs of sweating. If this doesn’t help, you may be advised to try treatments such as iontophoresis (the affected area is treated with a weak electric current passed through water or a wet pad), botulinum toxin injections, and even surgery in a few cases. Hyperhidrosis is usually a long-term condition, but some people experience an improvement with time and the treatments available can often keep the problem under control.
