Vitiligo is a kind of skin problem where white patches appear on different parts of the body. This kind of skin disorder is mainly due to the fact that the cells that make pigment in the skin are not working properly. Some of the common areas having white patches are hands, feet, arms, around the mouth, face, lips, armpits, eyes, groin, nostrils, navel and genitals.
About 0.5 to 1 percent of the world’s population, or as many as 65 million people, have vitiligo. In the US only, about two million people suffer from vitiligo. This skin disorder affects people belonging to all races and both sexes equally. It has been found that people suffering from hyperthyroidism are more likely to suffer from vitiligo.
