What is Vitiligo?
Vitiligo is a chronic skin condition in which patches of skin lose their pigment due to the destruction of melanocytes, the cells responsible for producing skin color, resulting in irregular white patches. It can affect any part of the body, including hair and mucous membranes, and tends to be progressive, though the rate and pattern of spread vary greatly between individuals. The condition is not medically dangerous or contagious, but can have a substantial psychological and social impact given its visible nature. Vitiligo is believed to be autoimmune in origin and often occurs alongside other autoimmune conditions.
Mild
Uncommon — affects about 0.5-2% of the global population
No
Causes of Vitiligo
Believed to result from an autoimmune process in which the immune system attacks and destroys melanocytes, though the exact trigger is unclear. Genetic predisposition plays a significant role, and vitiligo often coexists with other autoimmune conditions such as thyroid disease. Stress, sunburn, and skin trauma have also been reported to trigger or worsen patches in some individuals.
Symptoms of Vitiligo
Patchy loss of skin color, premature whitening of scalp or facial hair, loss of color in the mucous membranes inside the mouth and nose, changes in the color of the retina, patches that may grow or spread over time, symmetrical distribution
Treatment & Types of Vitiligo in Karnataka
Treatment options include topical corticosteroids or calcineurin inhibitors to help repigment affected areas, phototherapy using narrowband UVB light, and newer targeted therapies that modulate the immune response. Camouflage cosmetics and, in select stable cases, surgical skin grafting techniques can also be used to improve appearance.
Vitiligo is classified as non-segmental, the most common form, causing symmetrical patches on both sides of the body and typically progressing gradually over time, versus segmental, causing patches limited to one area or side of the body, often appearing earlier in life and progressing more rapidly before stabilizing. Non-segmental vitiligo is further described by extent as focal, involving a few isolated patches, or generalized, involving widespread patches across the body, with the pattern influencing both prognosis and treatment approach.

Frequently Asked Questions
Is vitiligo contagious or dangerous?
No, vitiligo is not medically dangerous or contagious, since it results from an autoimmune process destroying melanocytes rather than an infection, though it can have a substantial psychological and social impact given its visible nature. Understanding this can help address stigma or misconceptions others might have about the condition.
Can vitiligo be cured or reversed?
There is no guaranteed cure due to its autoimmune basis, but treatment options including topical corticosteroids or calcineurin inhibitors, phototherapy using narrowband UVB light, and newer targeted therapies can help repigment affected areas in many people. Early treatment tends to give better results at slowing progression and achieving repigmentation than waiting.
Is vitiligo hereditary?
Genetic predisposition plays a significant role, and vitiligo often coexists with other autoimmune conditions such as thyroid disease, so a family history of vitiligo or other autoimmune disease is a relevant risk factor. This doesn't mean vitiligo is guaranteed to develop even with a strong family history, since environmental triggers also play a role.
What triggers vitiligo patches to spread or appear?
Stress, sunburn, and skin trauma have been reported to trigger or worsen patches in some individuals, so sun protection to prevent burns on affected and unaffected skin is a recommended precaution alongside general vitiligo treatment. Managing these triggers doesn't guarantee preventing progression but is considered good general practice.
Does vitiligo only affect the skin?
It can affect any part of the body including hair and mucous membranes, and can also affect the color of the retina in some cases, though the visible skin patches are typically what brings people to seek evaluation and treatment. A dermatologist can assess the full extent of involvement during a comprehensive evaluation.
