Possible cause of profuse sweating: hyperhidrosis

From one moment to the next, the skin is covered with excessive sweat and large stains appear on clothing. When sweating suddenly occurs, those affected often do not even suspect that it is a disease. Often this will be extreme sweating dismissed as a genetically determined “peculiarity” of the body or shifted to a lack of fitness or too high body weight.

The disease in question is called Hyperhidrosis designated. Here, the sweat glands are overactive and therefore secrete an amount of sweat that exceeds the healthy level that is required, for example, to regulate body temperature. Hyperhidrosis also occurs when the body is at rest or when the temperature is low, so that those affected also under profuse sweating in winter Suffer.

What causes hyperhidrosis?

In primary hyperhidrosis, sudden sweats occur for no apparent cause. It is not yet clear why the sweat glands produce more sweat. It is believed that one Disorder in the autonomic nervous system causes larger amounts of the neurotransmitter acetylcholine to be released, which activates the sweat glands. It is still unclear what can trigger this disorder. A familial disposition seems to play an essential role here.

Causes of secondary hyperhidrosis

A second form of hyperhidrosis is that secondary hyperhidrosis. The profuse sweating is a consequence of another underlying disease or another trigger. Possible underlying diseases that can cause hyperhidrosis are, for example, hyperthyroidism, diabetes or tumor diseases. Neurological or mental illnesses can also lead to excessive sweating. Overweight, changes in the hormonal balance or menopause can also cause hyperhidrosis. In some patients, the use of certain medications is also the trigger for extreme sweating.

In order to find out the exact causes of the heavy sweats or to diagnose primary hyperhidrosis, a detailed anamnesis is essential. The doctor can only put together an appropriate and effective therapy on the basis of the individual medical history and a detailed examination.

Hyperhidrosis therapy with antiperspirants

The treatment of primary hyperhidrosis should above all be as gentle as possible, but still effective. The usage of Antiperspirants is one of the gentlest therapy options. The medicated sprays or creams are applied to the affected areas. Primary hyperhidrosis is usually located in the axillary area, but it can also occur in other parts of the body such as the back or feet. The medicinal antiperspirants ensure that the channels that lead from the sweat glands to the surface of the skin are narrowed. This reduces the amount of perspiration that is secreted. At the same time, the products care for the skin.

Remedy through botulinum toxin

In medicine is Botulinum toxin type A (Botox®) mainly known from the anti-aging area. In addition to wrinkle treatment, hyperhidrosis therapy is also one of the areas of application of the active ingredient. With the help of a Botox® injection, the release of the neurotransmitter acetylcholine is reduced. Since one of the tasks of the messenger substance is to send information to the sweat glands, for example, a smaller amount of acetylcholine has a direct effect on them Activity of the sweat glands out. If these do not receive the information to secrete sweat, the heavy and sudden sweating is also reduced.

Both antiperspirants and botulinum toxin do not achieve lasting results. They must be used or repeated regularly in order to maintain the sweat-reducing effect.

Sweat gland surgery

If the usual therapies with special medical products, botulinum toxin, relaxation exercises and other measures do not respond or only with inadequate results, then in severe cases of hyperhidrosis, a surgical intervention be advisable. There are various surgical procedures that are discussed individually with the patient. Often the sweat glands of the affected area are removed to prevent profuse sweating.
