What is hyperhidrosis?

The term hyper­hidro­sis refers to exces­sive sweat­ing that goes beyond the body’s need for ther­mal reg­u­la­tion. Peo­ple with hyper­hidro­sis sweat exces­sive­ly, regard­less of phys­i­cal exer­tion or ambi­ent tem­per­a­ture.

This dys­func­tion can lead to sig­nif­i­cant men­tal, social, and occu­pa­tion­al lim­i­ta­tions and can thus cause a marked reduc­tion in the qual­i­ty of life.

Hyper­hidro­sis can occur in dif­fer­ent parts of the body. Hyper­hidro­sis often occurs on the hands (hyper­hidro­sis pal­maris), on the face (hyper­hidro­sis facialis), on the soles of the feet (hyper­hidro­sis plan­taris), and in the armpits (hyper­hidro­sis axil­laris).

There are two types of hyperhidrosis

Local primary hyperhidrosis:

Focal hyper­hidro­sis, also called pri­ma­ry hyper­hidro­sis, is the most com­mon form of hyper­hidro­sis and affects only indi­vid­ual areas of the body, espe­cial­ly the armpits, feet, hands, or face. About 2–3% of the pop­u­la­tion suf­fer from focal hyper­hidro­sis. This dis­ease is wrong­ly con­sid­ered by many to be untreat­able.

As a rule, both halves of the body are equal­ly affect­ed by exces­sive sweat­ing. Focal hyper­hidro­sis occurs inde­pen­dent­ly of oth­er dis­or­ders and begins as ear­ly as child­hood or ado­les­cence. Exces­sive sweat­ing may begin imme­di­ate­ly after wak­ing up. Dur­ing sleep, how­ev­er, the affect­ed per­son usu­al­ly does not sweat, unless the ambi­ent tem­per­a­ture is gen­er­al­ly too high. Stress, anx­i­ety, or pain can increase the effects of hyper­hidro­sis.

Secondary hyperhidrosis:

Sec­ondary hyper­hidro­sis occurs as a result of an exist­ing, under­ly­ing con­di­tion or as a side effect of tak­ing med­ica­tion or dietary sup­ple­ments. Pos­si­ble dis­eases that can cause exces­sive sweat­ing are dia­betes, can­cer, obe­si­ty, gout, hyper­thy­roidism, and hor­mon­al imbal­ances (e.g. dur­ing menopause). This form of hyper­hidro­sis usu­al­ly affects the entire body. In con­trast to pri­ma­ry hyper­hidro­sis, exces­sive sweat­ing can also occur dur­ing sleep.
