Excessive sweating, also known as hyperhidrosis, is a disease that affects more and more people, causing a certain discomfort, sometimes leading to withdrawal. It is considered to be a real handicap both in private life and in professional life and for both men and women. Fortunately, there are several possible treatments with each its rate of effectiveness. But there is one that stands out.
How to define hyperhidrosis?
Hyperhidrosis can affect different parts of the body that are the hands, feet, and armpits.
For 10% of the people affected, it can be localized on the whole body. It is a disease that requires therapeutic treatment. It aims to help the people concerned to live like everyone else. You have to know that this can be a handicap on a daily basis. Hyperhidrosis can lead to bad odors, traces of sweat not pleasant to wear, impose several showers per day or changes of frequent outfits. In some trades, it can be a brake. For example, for a person with hyperhidrosis of the hands, it can stain the documents or have a bad grasp of tools.
The Iontophoresis is a treatment to combat transcutaneous hyperhidrosis which is based on passing an electric current through the skin. The iontophoresis facilitates the transport of molecules into the skin under the influence of an electric current (Fig. 1) which may be continuous or intermittent. Molecules in motion, of whatever substance, can thus be absorbed more easily or reach their destination more quickly than in other situations in which this movement is not provoked.
Appropriate Practice and Approved Devices for Iontophoresis
There are two types of iontophoresis currently for the treatment of hyperhidrosis, the first using tap water and the second based on agents Anticholinergics in solution.
Iontophoresis is a treatment against hyperhidrosis, uses tap water as a medium to transmit electrical current and this, in turn, mobilizes the sodium ions through the area of the body submerged in the water. This type of iontophoresis controls hyperhidrosis by disabling the function of the sweat glands. The mechanism by which this technique inhibits the functioning of the glands still remains without being completely understood although several hypotheses have been proposed in this regard.
In iontophoresis with anticholinergic agents the device used is the means by which the drug is promoted to the body through the skin for its eventual absorption. Its aim is to try to focus the effect only to certain areas instead of to the whole organism as with the oral medicines. The contraindications or side effects for this second type of iontophoresis are essentially the same as for any type of treatment with anticholinergic agents. The only difference is that, in this case, the drug is administered through the skin.
Contraindications against iontophoresis, in general, include pacemakers, pregnancy and prosthetic or metal implants, apart from these, in general, it is a safe treatment when done properly and with approved devices. It is recommended to check the standards with which these devices comply to ensure their proper operation and avoid side effects.
The success of iontophoresis depends on the amount of current applied in which generally 20ma at 25ma is considered as safe although in children it is recommended to use less current. It is also recommended to perform 3 or 4 sessions per week obtaining results generally between the 6th and 14th session which guarantees periods without sweating between 2 and 14 weeks. After the last session, maintenance sessions are held every 2 to 4 weeks.
Iontophoresis can have minor side effects such as excess dryness, reddish skin, and rashes on the skin that can be easily treated with emollients. However, the improper practice of iontophoresis may have more severe effects such as severe skin burns or necrosis. From the above the importance of using devices approved by health agencies. Also, the importance of using low voltage batteries as a source of power. Avoid using the home current when practicing this treatment.
FDA-approved machines for iontophoresis treatment device from the United States that is widely recommended for the proper exercise of iontophoresis. Some authors suggest that iontophoresis is only suitable in those areas of the body that can be easily submerged in the solution so that the face and underarms are beyond the scope of this type of procedure.
It is important to note that despite the side effects that incorrect use of iontophoresis may have, the practice of iontophoresis with approved devices is a completely safe method to stop hyperhidrosis quickly and effectively with the main characteristic of obtaining an extended effect.
