Visible signs of sweating may be noted during a doctor's visit. A number of tests may also be used to diagnose excessive sweating. Tests include:

Tests 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 color wherever there is excess sweat.
• Paper test. Special paper is placed on the affected area to absorb the sweat, then weighed. The heavier it weight, the more sweat has accumulated.

The patient may be also be asked details about the sweating, such as:

• Location
  • Is it on face, palms, or armpits?
  • Is it all over the body?
• Time pattern
  • Does it occur at night?
  • Did it begin suddenly?
  • How long have you had it?
• Triggers
  • Does it occur in response to reminders of a traumatic event?
  • What other symptoms are present (for example, weight loss, a pounding heartbeat, lack of appetite)?
  • Are the hands cold and clammy?
  • Is there a fever?
