The sweat glands on any area of the human body can be affected by hyperhidrosis but it is usually happens more often in the sweat glands of the palms of the hand, the soles of the feet and the armpits.

Diagnosis[edit | edit source]

In addition to history and physical examination, some of the test to help to diagnose excessive sweating include:

  • Starch-iodine test - An iodine solution is applied to the sweaty area. After it dries, starch is sprinkled on the area. The starch-iodine combination turns a dark blue to black color wherever there is excess sweat.
  • Paper test - Special paper is placed on the affected area to absorb the sweat, and then weighed. The heavier it weights, the more sweat has accumulated.
  • Blood tests - These may be ordered if thyroid problems or other medical conditions are suspected.
  • Imaging tests may be ordered if a tumor is suspected.

Treatment[edit | edit source]

Treatment depends on the cause. For secondary causes, treating the underlying cause is important. Treatment

A wide range of common treatments for hyperhidrosis includes:

  • Antiperspirants
