My palms are drenched lately. Is something scary happening?
—Theresa Excessive sweating, known as hyperhidrosis, usually affects the palms, soles, and/or underarms. When it crops up out of the blue, stress, anxiety or anti depressants may be to blame.
To control it, rub a topical anti perspirant on your hands at night. No improvement? Ask your derm for iontophoresis, a treatment that passes a safe, low dose of electricity through the skin via water for 20 minutes to microscopically thicken the skin’s outer layer, stopping sweat. (If it helps, you can buy an at-home machine.) Botox injections can block nerves that trigger sweat glands and acupuncture can halt excessive perspiration caused by stress. Should those not work or if you’re sweaty all over, oral meds, such as glycopyrrolate, inhibit chemical messengers that trigger sweating. Speak with your doctor to find the best solution for you.
If the sweating comes with other symptoms, it could be due to thyroid disease (rapid heart rate, increased appetite), cancer (lymphoma can cause weight loss) or menopause (irregular periods, low libido). In those cases, see your doc.
