Hyperhidrosis is excessive sweating that is unrelated to exercise or heat. It is not like regular perspiration. This condition can occur all over the body, such as in the hands, the armpits, and the feet. There are two main types of excessive sweating: primary and secondary hyperhidrosis.
Primary focal hyperhidrosis is most common and caused by overactive sweat glands that are stimulated by anxiety and stress. Secondary hyperhidrosis is less common. It stems from medical issues such as diabetes, menopause, and thyroid problems. Doctors must find the root causes responsible for the condition and treat those first. They usually order a sweat test and lab work. Depending on the case, doctors recommend different ways to manage excessive sweating. They typically begin with prescription antiperspirants or medication. If more intense solutions are needed, patients may have to undergo surgery.
A prescription antiperspirant is a topical treatment. Patients need to apply it to problem areas before going to bed and wash it off in the morning.
Nerve-blocking oral medications can minimize chemical reactions in the nerves that produce sweat. Antidepressants can lower sweat production and manage anxiety, which also affects hyperhidrosis.
Botox injections are non-invasive treatments that can treat hyperhidrosis. The neuromodulator temporarily stops communication in the nerves that produce sweat. The procedure will require several shots in each affected area. Patients can see results can last 6-12 months, with maintenance sessions needed to prolong its effectiveness.
Another hyperhidrosis treatment is iontophoresis. During this process, the hands and feet are placed on a tray filled with water for 20-30 minutes as electrical currents are released to temporarily shut down the sweat glands. The treatment is completely safe but will need 6-10 sessions for effective results.
Microwave thermolysis treatment, also known as MiraDry, uses microwave energy to damage sweat glands. Patients need two sessions lasting 20-30 minutes each for optimal results. For severe cases, sweat gland removal and nerve surgery can be an option.
