Compensatory hyperhidrosis
![Following Endoscopic thoracic sympathectomy surgery for axillary (armpit), palmar (palm) hyperhidrosis and blushing, the body may sweat excessively at untreated areas, most commonly the lower back and trunk, but can be spread over the total body surface below the level of the cut.](/Images/godic/202501/05/Gray5304148.png")
Compensatory hyperhidrosis is a form of neuropathy. It is encountered in patients with myelopathy, thoracic disease, cerebrovascular disease, nerve trauma or after surgeries. The exact mechanism of the phenomenon is poorly understood. It is attributed to the perception in the hypothalamus (brain) that the body temperature is too high. The sweating is induced to reduce body heat.
