RT Journal Article SR Electronic T1 In hyperhidrosis (excess sweating), look for a pattern and cause JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 896 OP 898 VO 70 IS 10 A1 Stolman, Lewis P. YR 2003 UL http://www.ccjm.org/content/70/10/896.abstract AB Hyperhidrosis (excessive sweating) can be generalized or localized, and secondary or primary; thus, understanding the pattern can help in finding the cause. Generalized hyperhidrosis may be due to an underlying systemic disease or to medication use. Focal hyperhidrosis is often primary (idiopathic) and triggered by emotional stimuli, although it is not generally a psychiatric disease.
