Suddenly they appear: Mostly numerous small bubbles between the fingers, on the palms or soles, filled with aqueous liquid. In most people they itch strong and often lead to unpleasant changes in the skin. About causes and treatment experts are divided. In many people affected, these bubbles occur especially in the warm months. It used to be thought that they were related to a malfunction of the sweat glands - hence the name (dys = miss, hidrosis = sweating). There is no direct correlation, but some of those affected have increased sweat production (hyperhidrosis).
Dyshidrosis: typical symptoms
Other names for dyshidrosis are the dyshidrotic or dyshidrotic eczema, as well as the pompholyx - which is also referred to in the hands as a chiropompholyx, on the feet as Podopompholyx (especially in large bladders).
The bursting blooms not only cause a strong itching, but after their bursting, the skin is often very dry and cracked.
Some sufferers develop large, inflamed and oozing skin areas; sometimes the hands or feet swell. For example, this can severely (and extremely painfully) interfere with grasping or walking. The bubbles come and go - sometimes sporadically, for example on the sides of the fingers, sometimes covering the entire palm or sole of the foot.
Causes of dyshidrosis
What causes the bulging bubbles filled with lymph fluid is still unclear. They are particularly common in people who suffer from atopic dermatitis, psoriasis or even an allergy such as nickel. It is also discussed that dyshidrosis is the result of heavy skin exposure (for example due to disinfectants) or fungal colonization on another external (for example athlete's foot) or inner body part (for example the intestine) and thus signs of an immune reaction.
Often, it also occurs depending on mental stress situations.
Also a hereditary component is discussed. Relationships with diet and stimulants such as coffee, alcohol and cigarettes are described, but are not proven.
Avoid allergy triggers
As manifold as the triggers discussed are also the treatment options. Not infrequently, the suffering stories of those affected last for years without the disease being cured.
If triggers are known, these should be avoided. It may therefore be helpful to do an allergy test. Also, a diet change - for example, a low-dairy and meat-poor diet, waiver of cheese, onions and peppers (tip from Chinese medicine), no alcohol, coffee, not smoking - is definitely worth a try.
Local treatment of dyshidrosis
The local treatment of the skin with creams or baths rarely leads to a cure, but can improve the itching and the appearance of the skin and support further measures.
The range of possible active ingredients includes, for example:
- Tanning agents (for example Tannosynt® or baths with oak bark extract, sage or apple cider vinegar)
- Wound and protective creams with zinc (even those that are otherwise used for a sore baby's poppy) or urea (urea)
- mostly fatty cortisone albums (for short-term use)
Cortisone can also be taken as tablets for a few days to weeks in the case of severe complaints. Even drugs such as neogitasone or alitretinoin, which are used in psoriasis, can help in severe cases.
In alternative medicine, rehabilitation of the intestine (in which many immune processes take place) is recommended for example by means of microbiological therapy and diversion methods, homeopathic remedies and methods of Far Eastern medicine such as acupuncture and Chinese or Tibetan herbal medicine. The basis of these concepts is the view that skin disorders are only the visible part of fundamental processes taking place in the body, thus requiring a holistic approach.
Relaxation-enhancing techniques can help to reduce stress and relieve the relapses. In principle, those affected need a lot of patience; Ultimately, it has to be tried on individually, what helps and what does not.
