Vitiligo is a chronic autoimmune skin condition that causes white patches due to the loss of skin pigment. Many people worry that it may spread across the entire body, but in most cases vitiligo remains limited to certain areas. Only a rare form, known as universal vitiligo, affects a large portion of the skin.

The condition is not contagious and cannot spread through touch or food. Factors such as genetics, autoimmune activity, stress, and skin injury may influence its progression. Early diagnosis and proper treatment can help manage the condition and slow the spread.

With the right care, lifestyle support, and medical guidance, many people with vitiligo are able to control its progression and maintain healthy, confident lives.
