Sweaty Palms
Q: I have an embarrassing problem. My palms sweat so much they get slick,
even when I'm not feeling hot or nervous. It's so bad I won't
shake hands when I meet someone new. I know I seem rude, but I'm too mortified
to touch anyone. Is there anything that can help me?
Dr. Donnica: Take heart! There is help for palmar hyperhidrosis (the medical
term for palms that sweat profusely), a condition that occurs when misfiring sympathetic
nerves overstimulate sweat glands in the hands. Hyperhidrosis affects approximately
1% of the population, anywhere (or everywhere) in the body, and it may be episodic
or continuous.
The first step is to identify and treat any possible underlying causes, such
as stress, or underlying medical conditions, such as infections, thyroid problems,
malignancies, obesity, or menopausal hot flashes. For true hyperhidrosis, treatment
options include over-the-counter (e.g. Odaban, Certain-Dri, or Maxum) or prescription
antiperspirants (e.g. Drysol), oral medication (anticholinergics), botulinum
toxin (Botox™) injections, and iontophoresis (applying low intensity electric
current to the hands or feet immersed in an electrolyte solution).
While OTC and prescription antiperspirant lotions are not highly successful
in patients with palmar hyperhidrosis, they should be tried before moving on
to other, more invasive and expensive therapies. Note that when using these
products, their instructions say "for underarm use only," but they
can be applied directly to the hands. I recommend using them just before bedtime,
as the lotion itself will make your hands wetter. Outpatient surgery (endoscopic
thoracoscopic sympathectomy) is a last resort, but at established medical centers
it can be up to 98% successful. Ask your doctor to recommend a treatment course
that's best for you.
