What is it?

Hyperhidrosis is another way to say excessive sweating.

~ 2-3% of Americans suffer from excessive sweating of the underarms or of the palms and soles of the feet.

~ Underarm problems genuinely start in late teen years, while palm and sole sweating begins younger such as 13 on average.

~ Anyone can be affected by this condition but people with certain medical conditions like diabetes and gout can have excessive sweating too.

What causes it?

Heat and emotions could trigger hyperhidrosis in some people, but others who suffer from hyperhidrosis sweat all the time, regardless of their mood or the weather.

Symptoms of Hyperhidrosis

  • Clammy or wet palms of the hands
  • Clammy or wet soles of the feet
  • Frequent sweating
  • Noticeable sweating that soaks through clothing.

Tests for Diagnosis

  • Iodine-starch test
  • Thermoregulatory sweat test
  • Skin conductance


Prevention & Prognosis

Early on over the counter antiperspirants can help with this condition. But it runs a chronic course, causing only a small number of people to improve after the age of about 25.
