Causes of Secondary Hyperhidrosis

Secondary hyperhidrosis can be caused by a variety of underlying conditions and can be categorized by area of involvement — local versus generalized. There are some rare dermatologic syndromes known to cause localized hyperhidrosis. The association of social anxiety disorder and other psychiatric conditions with hyperhidrosis has also been studied. Additionally, secondary hyperhidrosis may be a side effect of medication.
