Excessive Sweating: Embarrassing, Treatable
Nearly 8 Million Americans Affected, but Help Is Available

Other available treatments include:
Prescription antiperspirants, the typical
first-line treatment. "They work but can cause skin irritation, redness,
and stinging," says Glaser.
Medications such as antidepressants,
tranquilizers, and a type of high blood pressure medication known as calcium
channel blockers. These drugs, which have a "drying" effect, are
primarily used to control sweating caused by stressful situations.
Surgery to either remove the sweat
glands or sever nerves leading to them. But in the procedure to remove underarm
sweat glands, range of motion problems of the arm are a common side effect,
"But with Botox, you hit a home run every time," says
Glaser, vice chairwoman of the department of dermatology at Saint Louis
University School of Medicine.
Waldorf agrees and tells WebMD that Botox injections are even
used "cosmetically" in people who don't have hyperhidrosis but want to
ensure they don't sweat during special occasions.
"Let's say you're making an important presentation or it's
your wedding and you are concerned about sweating too much. You get an
injection," she says. "Even celebrities are getting Botox injection in
the weeks before the Academy Awards because they know they'll be on stage in

The exact cause of hyperhidrosis is not completely understood.
"We've determined that these patients have sweat glands that are normal in
size, number, and function," Glaser tells WebMD. "What seems to be
driving this is that signals from the brain cause these people to sweat
excessively, not because of heat or from exercise, when it's not necessary to
control that much to maintain normal body temperature."
The condition affects men and women equally and has no
geographic influence -- those in colder climates are as prone as those in
hotter areas. It does seem to run in families, with about half of patients
reporting a similarly afflicted relative, says Glaser. It typically first
appears following puberty and rarely affects infants.
"What separates hyperhidrosis from other sweating is its
excessiveness and the fact that it is localized to specific areas," says
Glaser. "With menopause, you may sweat all over. With hyperhidrosis, you
only sweat in your underarms or palms or soles or face, either an individual or
some combination of those specific areas."
And unlike the sweating that may accompany social anxiety
disorder, hyperhidrosis often occurs in "calm," everyday situations --
although it can be aggravated by stressful events.
"It's not a subtle thing, and most people with it know they
have it," adds Waldorf. "This research shows what we've suspected --
that it is more common than some believed. Hopefully, people with this disease
will also learn that it can be effectively treated."
