Causes of Vitiligo
The major cause of vitiligo is the loss of pigment producing cells in skin. Our body contains melanocytes cells, special cells that produce melanin. Melanins are in yellow, brown, dark brown pigment that determines skin color. These melanin cells further produce pigment cells in skin. These pigments are the coloring matter in the cells & tissues of body. If due to any disorder, melanocytes cells fails to produce pigment cells then we term it as depigmentation in skin. Due to this depigmentation, skin shows white spots or patches. The other causes related to depigmentation are given below
Almost 10 to 20 % people found in vitiligo, because of getting an autosomal dominant gene, with irregular pattern from their parents.
Vitiligo can be appeared by mental disturbance, or taking hyper level of stress, tension, anxiety etc.
3) Dietary Insufficiency
Lacking of nutritional factors in body may leads to vitiligo.
4) Old physical injury
Mostly in children’s old physical injury like, cuts can modify the skin coloration.
5) Sun exposure
Due to the less sensitivity in skin to face sun light, many people indulge in this disease, if they face a sun ray that damages the skin cells & tissues and pigmentary cells.
Diagnose of vitiligo
Physicians easily diagnose the vitiligo disease, because of the appearances of white patches on skin.
Affected People from vitiligo
40 to 50 million people in world wide, with the 1-2 percentage of the world, is suffering from the disease.
Vitiligo & hair
Vitiligo changes the hairs color, due to the loss of melanocytes from the basal follicular epithelium over the hair papillae.
