What is Palmar Hyperhidrosis?

Palmar Hyperhidrosis, or sweaty palms, is the most common symptom of Hyperhidrosis and can be the most socially disturbing. Palm sweating can be accompanied by hyperactive feet sweating and armpit sweating, but palmar sweating is the most difficult to control and is the most troubling.

Cause of Palmar Hyperhidrosis

Palmar Hyperhidrosis is caused by hyperactive sweat glands in the hands. Instances such as holding hands or shaking one’s hand may excessively stimulate the sweat glands in the hand leading to unusually sweaty hands.

Symptoms of Palmar Hyperhidrosis

  • Excessively clammy and sweaty hands
  • Sweating in the hands from everyday tasks such as writing with a pencil or holding hands with someone
  • Fear of situations that require hand contact

How is it diagnosed?

Your doctor may recommend a series of tests to pinpoint the hands as a location of excessive sweating and determine the severity of the disorder.

Palmar Hyperhidrosis Treatment Options

At the Center for Hyperhidrosis at Columbia University Medical Center, we use a team approach to evaluate and treat all patients with palmar hyperhidrosis. We first recommend a series of non-invasive, topical remedies. If the patient does not respond to non-surgical remedies, we may recommend surgery, but only in severe instances.

  • Botox® – Binds receptors to prevent activation of sweat glands.
  • Medical Therapy – Oral prescription treatment to prevent the stimulation of sweat glands.
  • Iontopheresis – Treatment specifically for sweaty hands that utilizes a mild electric current through water to reduce hyperactive sweat glands.
  • ETS – A minimally invasive surgery that is the best treatment for patients with severe Palmar Hyperhidrosis.
