Vitiligo affects approximately 0.5% to 2% of people worldwide. Although it’s considered rare, its visibility has been highlighted by the iconic pop music legend Michael Jackson, whose skin discoloration was widely known. But what precisely is vitiligo, and how can one determine if they have it?
Understanding Vitiligo
Vitiligo is a condition characterized by the loss of skin pigmentation, resulting in white patches on the skin. Unfortunately, the exact causes of vitiligo remain unknown. Researchers speculate that it may stem from an autoimmune response triggered by environmental factors.
Who is Affected by Vitiligo?
Vitiligo can affect individuals of any demographic group, with no apparent predisposition. Both men and women are equally susceptible. However, it tends to be more noticeable in individuals with darker skin tones. While vitiligo can develop at any age, it typically emerges before the age of 40, with approximately half of cases diagnosed before the age of 21. It’s essential to note that vitiligo is not contagious.
Types of Vitiligo
Recent consensus suggests that vitiligo can be categorized into two main types:
- Non-Segmental Vitiligo (NSV): This is the more prevalent form, affecting multiple areas of the body. NSV patches often exhibit some degree of symmetry in their distribution.
- Segmental Vitiligo: This variant tends to impact specific body parts or limbs.
Signs of Vitiligo
Diagnosing vitiligo can be challenging due to the diversity of skin irregularities. However, here are five common signs that may indicate vitiligo:
- Patches of Paler or White Skin: Well-defined patches of white skin are characteristic of vitiligo. These patches occur when pigment-producing cells cease melanin production, which gives skin its color.
- Changes in Eye Color: Vitiligo may affect pigmented cells in the iris and retina, leading to changes in eye color.
- White Hair: Unexpected greying or whitening of hair, eyebrows, eyelashes, or facial hair may accompany skin depigmentation.
- White Patches Inside the Mouth: Mucous membranes can also be affected, resulting in loss of pigmentation inside the mouth and nose.
- Associated Diseases: A significant proportion of vitiligo patients also present with autoimmune diseases, such as thyroid disease and alopecia areata (sudden hair loss).
Treatment Options for Vitiligo
While there is no cure for vitiligo, several treatment options can help manage symptoms and restore skin color, depending on individual circumstances:
- Topical immune-suppressing medications
- Phototherapy
- Cosmetic camouflage makeup
For extreme cases, depigmentation may be considered as a method to achieve uniform skin color by removing pigment from unaffected areas.
