Tapwater iontophoresis

The function of perspiration

At increased ambient temperature or in phases of heightened bodily activity, the body excretes watery fluid through the pores of the skin.


The evaporating sweat forms a layer of cool air on the body surface, protecting the organism from overheating by keeping the body temperature constant.


The vegetative nervous system controls the perspiration and cannot be influenced intentionally.


Cause for excessive sweating

Different factors like overweight, fever, low blood sugar level (diabetes), etc.


Factors to cause excessive sweating other than increased ambient temperature or bodily activity, are:


  • nervousness, anxiety and stress
  • overweight
  • hormonal changes, e.g. menstruation, pregnancy and climacterium
  • an overactivity of the thyroid gland
  • fever
  • low blood sugar level in case of diabetes
  • taking of certain drugs, e.g. cortisone


Symptoms of Hyperhidrosis (excessive sweatin)

Approx. 1 % of all people suffer from excessive sweating, the so-called Hyperhidrosis


Some people sweat profusely although none of the above mentioned causes exist. It is caused by a dysfunctional control of the sweat secretion by the vegetative nervous system.


The persons’ natural control of their sweat glands is in disorder. They are working on too high a level. These symptoms are often due to genetic conditions which may begin to show as early as in childhood or puberty.


Excessive sweating can occur on every part of the body. Usually, a person will sweat profusely only on the palms, soles and in armpits.


The psychological stress caused by profuse sweating can be severe to persons suffering from it. Because of clammy hands, disgustingly smelling feet and strongly sweating armpits these persons often avoid social contacts. Moreover, clammy hands can be a restriction in carrying out daily tasks in your professional and private life. 


Iontophoresis for treatment of Hyperhidrosis


In 1936, the first positive experience were made with Iontophorese for the treatment of hyperhidrosis. Tap water-Iontophorese can substantially improve or even remove excessive sweating within a short period of time and, all this without any drugs, side effects or operations.


A positive effect is attained by rising the stimulus threshold of the sweat gland secretion thus  providing an effective treatment. A treatment with Iontophorese is successful in up to 98 % of the cases. In Germany, the tap water Iontophorese is the therapy most frequently chosen for treating excessive sweat on hands, soles and in armpits.


Application of tap water iontophoresis


The body regions concerned, such as hands and feet are put into two plastic tubs filled with tap water.


Via electrodes a weak electric current is led into these tubs.


The strength of the current is individually-controlled. The patient should perceive no more than a very slight tingling.


This treatment should be carried out for approx. 10 to 15 minutes daily until an improvement can be felt.


After that, one or two treatments per week are sufficient to maintain the positive effect.


After a successful start of the therapy in a General Practitioner’s practice and a written prescription by your GP, the health insurance company will in most cases agree to cover the costs of an Iontophorese instrument for private use. Nevertheless, your General Practitioner should get a feedback on this matter from time to time.
