Diagnosis

During your appointment, your doctor will ask about your medical history and symptoms. You may also need a physical exam or tests to further evaluate the cause of your condition.

Lab tests

Your doctor may recommend blood, urine or other lab tests to see if your 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, including an iodine-starch test, skin conductance and a thermoregulatory sweat test.
