Understanding Vitiligo
Vitiligo is a long-term autoimmune skin disorder that causes patches of skin to lose their natural color. This happens when melanocytes—the cells responsible for producing melanin—are destroyed or stop functioning properly.
Melanin is the pigment that gives color to the skin, hair, and eyes. When melanocytes disappear from certain areas of the body, the affected skin becomes lighter or completely white.
Vitiligo can occur in people of all races, ethnicities, and skin tones. However, it is often more noticeable in individuals with darker skin because the contrast between affected and unaffected areas is more pronounced.
The condition affects approximately 0.5% to 2% of the global population, making it relatively common. Millions of people worldwide live with vitiligo, including celebrities, athletes, and public figures.
Although vitiligo changes appearance, it is not contagious and cannot be spread from one person to another through physical contact.
What Causes Vitiligo?
Scientists do not fully understand the exact cause of vitiligo, but most evidence suggests that it is primarily an autoimmune condition.
In autoimmune diseases, the body’s immune system mistakenly attacks healthy cells. In the case of vitiligo, the immune system targets melanocytes, leading to a gradual loss of pigmentation.
Researchers believe several factors may contribute to the development of vitiligo:
Genetic Factors
Vitiligo often runs in families. Studies indicate that individuals with a family history of vitiligo or other autoimmune diseases may have a higher risk of developing the condition.
Certain genes associated with immune regulation appear to increase susceptibility.
