Conditions We Treat: Excessive Sweating (Hyperhidrosis)

Hyperhidrosis means excessive (too much) sweating. It is caused by an overactive sympathetic nerve, and it is a medical condition. This condition can make people feel embarrassed and isolated. Treatment can help facilitate a life free of the worry of excessive sweating.

  • Our doctors are very committed to finding the right treatment for hyperhidrosis patients to improve their condition as well as their quality of life.
  • Hyperhidrosis usually occurs in the palms, underarms and feet. It can also occur on the scalp and on the trunk of the body.
  • There are many treatments for hyperhidrosis, including medications, botulinum toxin, iontophoresis and a new promising treatment known as microwave thermolysis.
  • Surgery is also a treatment for hyperhidrosis, and is known as a thoracic sympathotomy. Our doctors at Johns Hopkins have performed hundreds of these surgeries.

Why choose Johns Hopkins for treatment of hyperhidrosis?

We manage hyperhidrosis through a group of specialists who have been evaluating and treating patients with hyperhidrosis for nearly two decades. Our dermatologists are often on the front line of treating hyperhidrosis, and work closely with our surgeons, when surgery seems to be the best option for that patient. Behavioral medicine specialists can help you address emotional issues that stem from your condition and to build new social skills as part of your treatment. Neurologists are also a part of the treatment team when the cause of excessive sweating may have a neurological cause.
