Understanding Vitiligo (Leucoderma)
Vitiligo is an autoimmune skin disorder in which the body's own immune system attacks and destroys melanocytes — the cells responsible for producing melanin, the pigment that gives skin its colour. This results in smooth, white patches appearing on various parts of the body. Vitiligo affects approximately 1-2% of the global population, but India has one of the highest prevalence rates at 0.5-2.5%, with some studies suggesting even higher numbers due to underreporting.
In India, vitiligo carries a disproportionate social and emotional burden. Often mistakenly associated with leprosy or considered "impure" in traditional beliefs, patients face severe stigma that affects marriages, employment, and social interactions. It is essential to understand that vitiligo is purely a cosmetic autoimmune condition — it is not contagious, not caused by diet or karma, and does not affect any organ other than the skin. Modern dermatology has made remarkable advances in repigmentation therapies, and early treatment significantly improves outcomes.
Vitiligo can develop at any age, though it most commonly appears before age 30. The course of the disease is unpredictable — some patients experience slow, gradual spread over years, while others see rapid progression. A dermatologist specializing in vitiligo can assess your disease activity, identify the type and extent, and recommend the most appropriate treatment strategy based on the latest evidence-based guidelines.
