FAQWho is prone to vitiligo?


Vitiligo can affect anyone, regardless of gender, age, or race. Vitiligo prevalence is between 0.76% and 1.11% of the U.S. population, including around 40% of those with the condition being undiagnosed. Scientists know that some people are genetically predisposed to a specific group of autoimmune diseases – including generalized vitiligo – but do not exactly know who and why. 

The prevalence of vitiligo can vary slightly across different regions and populations. Some individuals may have a higher risk of developing the condition due to a combination of genetic and environmental factors. For instance, exposure to certain chemicals or intense sunlight could potentially contribute to the development of vitiligo, and these factors can be more prevalent in some regions than others.

Here are some groups who are more prone to vitiligo:

  • People with a family history of vitiligo: If you have a close blood relative with vitiligo or an autoimmune disease such as lupus, rheumatoid arthritis, or type 1 diabetes, you may be more likely to develop vitiligo.
  • People with certain genetic variants: Certain genes associated with the immune system may increase the risk of developing vitiligo.
  • People with existing autoimmune conditions: Individuals with autoimmune conditions, like hyperthyroidism, alopecia areata, pernicious anemia, or Addison's disease, are at a higher risk of developing vitiligo.
  • People of certain age groups: Vitiligo often begins at around age of 20, although it can start at any age.
  • People living in certain geographic areas:  .

Remember, while these factors can increase the risk, they do not guarantee that an individual will develop vitiligo. Many people with these risk factors never develop the condition, and others without these risk factors do. If you have concerns about vitiligo, it's important to consult with a healthcare professional for a proper diagnosis and treatment plan.
