This is in contrast to generalized hyperhidrosis which tends to occur in an older age group.

Barankin says that there are two basic types of excessive sweating: localized hyperhidrosis and generalized hyperhidrosis.

Hyperhidrosis may also be divided into palmoplantar (symptomatic sweating of primarily the hands or feet), gustatory and generalized hyperhidrosis.

Generalized hyperhidrosis is excessive sweating that may be induced by febrile diseases, vigorous exercise, or a hot, humid environment, such as a tropical milieu.

Secondary hyperhidrosis (also called generalized hyperhidrosis) causes excessive sweating all over the body or in a larger area of the body and is caused by a medical condition or medication.
