Most patients with essential hyperhidrosis will not need any testing. This pattern of sweating usually starts in childhood, and may involve the hands, feet or underarms. It is not present during sleep, and usually affects both sides of the body. Some cases of excessive sweating require tests for thyroid function, blood sugar levels and other hormones. This will be discussed with you during your consultation.

In some cases, to determine the extent and severity of sweating, we may perform a Starch Iodine test. This can give us a accurate method of determining severity and areas involved, especially for underarm sweating.
