What is Hyperhidrosis?

Approximately 1% of adults suffer from hyperhidrosis: A disorder that leads to excessive sweating in regular activities that do not typically activate your sweat glands.

Cause of Hyperhidrosis

Hyperhidrosis is caused when the automatic stimulation of your sweat glands is hyperactive. The response to stress, increased temperatures, and other instances may excessively stimulate sweat glands specifically in highly concentrated areas such as the hands, feet, armpits, and genital regions.

In a majority of people, the automatic response to stress and increased temperature does not excessively stimulate the sweat glands; however, people who have hyperhidrosis have hyperactive sweat glands that leads to excessive sweating.

Symptoms of Hyperhidrosis

  • Excessively sweating in hands, feet, and armpits
  • Sweating from everyday tasks like taking notes in class or shaking someone’s hand
  • Excessively blushing on the face, neck, and upper chest
  • Visible sweating that soaks through clothes

How is it diagnosed?

Your doctor may recommend a series of tests including a blood, urine, and sweat test to determine if excessive sweating is caused by hyperactive sweat glands or another condition such as an overactive thyroid or low blood sugar.

To identify the areas of hyperactive sweating and the severity of the disorder, your doctor may recommend an iodine-starch test, skin conductance, or thermoregulatory sweat test.

Hyperhidrosis Treatment Options

Treatment for Hyperhidrosis is often minimally invasive and topical, and we typically only recommend surgery to patients with severe Hyperhidrosis.

  • MiraDry® – A non-invasive treatment specifically for excessive underarm sweating.  
  • Botox® – Binds receptors to prevent activation of sweat glands.
  • Antiperspirants – Over-the-counter treatment to prevent sweat from reaching the surface.
  • Medical Therapy – Oral prescription treatment to prevent the stimulation of sweat glands.
  • Iontopheresis – Treatment specifically for sweaty hands and feet that utilizes a mild electric current through water to reduce hyperactive sweat glands.
  • ETS – Minimally invasive surgery for patients with severe palmar hyperhidrosis (sweaty hands).
