Hand sweat may occur independently or in combination with sweating of the armpits, face and scalp, or feet. Facial blush may also be present. This condition causes severe dripping sweat from the armpits. Excessive sweating of the feet is the result of over-stimulation of the sweat glands in the feet by the sympathetic nervous system.
Facial blush is caused by overstimulation of the sympathetic nervous system.
The cause of secondary hyperhidrosis may be due to chronic infections, hyperthyroidism, autoimmune disorders, malignancy or other factors. A thyroid test is often recommended to people with excessive sweating to verify that their hyperhidrosis is not due to hyperthyroidism. The diagnosis and work-up of secondary hyperhidrosis is usually made by a knowledgeable internist. These disorders are not responsive to a sympathectomy. All rights reserved.
