Vitiligo: causes and symptoms
Vitiligo refers to a skin disease in which there is a violation of metabolism in the skin, and as a consequence, lose pigmentation. In the core of the problem-the destruction of melanin, which does not cover all skin, but only its separate parts.
The problem occurs in scattered on the surface of the body white spots, which is especially noticeable in people with dark skin. Occur this problem may almost any age as men, and women.
The exact causes of vitiligo and no one else could provide, but we can say that the disease is not a contagious and cannot be transmitted from someone who them more healthy person.
Modern medicine is grappling with the problem of vitiligo quite thoroughly, as the disease began to appear increasingly among young people. To what is already known about the disease, can be attributed to several factors that can be underlying cause of vitiligo:
- In violation of metabolism in the body in which the violation of some of the functions of such glands as the thyroid, adrenal, reproductive, pituitary gland.
- Frequent stress or psychological trauma. The physical factors can be related and autoimmune diseases or postponed organism of the disease infectious origin.
- In addition, vitiligo may begin to form when ingested parasites, we are talking about hlystova penetration.
- The development of vitiligo may be the result of a catastrophic lack in the body of certain trace elements such as iron, copper or zinc.
Some doctors tend to believe that vitiligo can be classified as diseases hereditary nature. These conclusions can be reached, observing of vitiligo, some of your family members. So, the hereditary line of the disease is possible.
Vitiligo often has the form of a chronic disease for a long period of time, generally not appearing, leaking entirely asymptomatic, which complicates the possibility of timely diagnosis.
The first symptoms can begin quite suddenly with the fact that on the skin begin to appear small spots with clearly defined borders. Spots can be presented in white or pale pink.
Over time, the spots begin to grow in size, capturing the adjacent areas of the skin and merging into one vast area of destruction.
It should say why vitiligo is so much negative perception that all the spots are localized precisely on the skin of exposed areas, and often they affect the skin of the face, feet, knees, neck, and hands. Thus, vitiligo is never observed on the soles or palms, do not have it on mucous. Asa rule, the white patches with the destroyed pigment formed symmetrically, but there are cases where the pigment is destroyed on one of the limbs without symmetry.
Another symptom of playing the very spot, because unlike most skin diseases in vitiligo affected area no flakes, no atrophy.
The following clinical manifestation is the loss of sensitivity in the affected area of the skin. Here one can observe an infringement of the output of sweat from the sebaceous glands, and hair can change the original color, which once again proves vitiligo because melanin is destroyed.
In vitiligo can develop solar dermatitis, in this case, patients are recommended to eliminate direct sunlight on the affected areas of the skin, and limit your stay under the sun.
The most difficult stage, and symptoms show it instantly, is the beginning of a universal destruction of the skin when melanin is destroyed around the skin.
What still needs to be emphasized is the fact that the symptoms is built just for the visual definition of the problem, because at the level of perception the patient does not feel any changes, no itching, no pain, no irritation of the skin. That is vitiligo is a cosmetic problem in the first place.
Visually vitiligo is allocated to open areas of the body, but so far not found the negative side of the skin lesions in this disease on the body as a whole.
Interestingly, vitiligo can completely spontaneously disappear, leaving no trace, but such cases are rare.
Treatment of vitiligo today have not been developed, there are only a few ways that partially restore the pigmentation of the skin, but one universal method still not implemented and not developed.
