Tests and diagnosis

By Mayo Clinic Staff

During your appointment, your doctor will ask about your medical history and conduct a physical exam. If your symptoms are obvious, it may be relatively easy for your doctor to diagnose hyperhidrosis.

Lab tests

Your doctor may order blood or urine tests to determine if the excessive sweating is caused by another medical condition, such as an overactive thyroid (hyperthyroidism) or low blood sugar (hypoglycemia).

Sweat tests

A number of tests are available to pinpoint the areas of sweating and estimate the severity of your condition. These include:

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