Recent Studies

Some dermatologists consider vitiligo as a degenerative disease and it really is pigmentation disorder of skin, caused by central nervous system, characterized by destruction of producing melanocytes cells of the pigment that give color to skin.

The affected person usually has variable state concerns with anguish and despair. It is possible to find history of important emotional disorder or sudden severe emotional shock or just stress such as accident, bereavement of close relative, etc as they usually cause this disorder, particularly in children of rejection and mockery.

The recent studies show that vitiligo is caused by increasing quantity of adrenaline in bloodstream which generates overload in function of spleen, liver, kidney and pancreas and toxins which do not remain capable of elimination.

These toxins are gather in liver and in other organs responsible for elimination leading to melanocytes which remain indifferent in basal layer as a result of lack of blood flow, making melanocytes lose the function and remain intact in basal cells as indifferent, performing no function to make melanin, a substance which gives color to skin.

As a part of this waste accumulation in liver, symptoms occur in the patients of vitiligo including lack of pigmentation, headache, abdominal pain, depression and itching in the areas of lesions.

It is important to clarify that Vitiligo is not contagious illness and health is not at severe risk, but white spots affect emotional aspect of the person making him/her irritable, aggressive or very shy.
