Primary Focal Hyperhidrosis

Primary focal hyperhidrosis is excessive sweating that is not caused by another medical condition (i.e., “primary”), and it occurs in one or more “focal” areas (e.g., underarms, hands, feet, face and head, groin, breasts, and back) on both sides of the body (e.g., both underarms, both hands, etc.). Most patients experience excessive sweating in more than one focal area.

Primary focal hyperhidrosis often begins in childhood or adolescence. Interestingly, most patients do not experience excessive sweating at night while sleeping. Primary focal hyperhidrosis also appears to have a genetic component meaning that you can inherit the disease from a parent.
