Vitiligo causes white patches on your skin. It can also affect your eyes, mouth and nose. It occurs when the cells that give your skin its color are destroyed. No one knows what destroys them. It is more common in people with autoimmune diseases, and it might run in families. It usually starts before age 40.

The white patches are more common where your skin is exposed to the sun. In some cases, the patches spread. Vitiligo can cause your hair to gray early. If you have dark skin, you may lose color inside your mouth.

In the United States, 1 to 2 million people have the disorder. Most people with vitiligo develop it before their 40th birthday. The disorder affects all races and both sexes equally. People with certain autoimmune diseases (such as hyperthyroidism) are more likely to get vitiligo than people who don't have any autoimmune diseases.
