Causes of Vitiligo

Vitiligo is a skin condition in which some parts of the body turns into white spots. It is pigmentation disorder in which pigment producing cells the Melanocytes are destroyed and the autoimmune system perform anomial behavior. Most often, patients apart from vitiligo have a healthy body. Vitiligo may appear any part of the body but normally it appear on the exposed part of the body like face, hands, arms, eyelids, neck and foot etc. The hair may also turn white that grows in areas affected by vitiligo.

Vitiligo has the close relation with autoimmune system of the body, but if we ask that Vitiligo is the common anomaly of the autoimmune system of the body then it would not be wrong. In Vitiligo the Melanin producing process of the skin is disturbed due the internal factor. Melanin is a substance play key role in determining the skin color. Its is produced by the pigmentation producing cells Melanocytes.

Cause of vitiligo:

The genetic factor of the disease not yet clear except this that a NLAP1 gene is responsible for this skin disorder. There is very low involvement of the inheritance factor in the skin condition Vitiligo, and not fully clear.

There are several theories exist for regarding the causes of vitiligo.
But no actual fact is fully known. But all famous theories claim the destruction of melanocytes cell for the real cause of vitiliog. Hereunder the four popular theories regarding regarding the cause of vitiligo explained.

1) An abnormal functioning of certain nerve cells produce a toxic substance which damages the Melanocytes cells. It seems that this cause is related to the emotional factor or the stress which vitiligo patients has to suffer due to his appearance. This causes the increasing progression of vitiligo under the influence of the stress.

2) Some enzymes causes An alteration in the immune system of the body This change results in the destruction of pigment producing cells and hence the production of the melanin substance disturbed.

3) Some experts say that a genetic defect in the body causes Vitiligo.

4) Another hypothesis is that an antibodies produces in the system which destruct the melanocyte cells.

We also believe that this could be a combination of these four theories.

Breif Statistics about vitiligo

Vitiligo affects all races and both sex equally. According to the statistics about 40 to 50 millions people are currently suffering from this skin condition it means 1 to 2% of total population across the world. Vitiligo is also called Michael Jackson disease. In UK the percentage of vitiligo patients is 1%.In USA 1 to 2 million people have vitiligo.
Mostly the people having age below the 40 are become the victims of vitiligo.

One good thing about vitiligo, is not infectious disease and affected population with vitiligo are in good condition overall. As for as concern with inheritance factor associated with vitiligo, about 20% of the patients of vitiligo are those have a family background with vitiligo.

Symptoms and appearance of vitiligo:

1)The main symptom of vitiligo is the white patches on the skin. It is obvious on relatively dark skin and it difficult to observe on white races except in summer.
2)Sunburn is a common symptoms of vitiligo because UV protective cells have been destroyed in this skin disorder.

Does the vitiligo is curable:

If we talk about the treatment of vitiligo the complete cure from this is a very difficult thing. It is possible by using oral or topical treatments one contain white patches but cannot cure vitiligo or halt it.
Among the dozens of different treatment and method I think the Herbal medicine are best because these has low cost, easily available and very important thing has no side effects.
