Vitiligo is caused by the lack of a pigment called melanin in the skin. Melanin is produced by skin cells called melanocytes, and it gives your skin its colour. In vitiligo, there are not enough working melanocytes to produce enough melanin in your skin. This causes white patches to develop on your skin or hair.
What causes vitiligo? Vitiligo is an autoimmune disease. This type of disease develops when your immune system attacks part of your own body. If you have vitiligo, your immune system attacks cells in your body called melanocytes. These are cells that make pigment.
Anyone can get vitiligo, and it can develop at any age. However, for many people with vitiligo, the white patches begin to appear before age 20, and can start in early childhood.
Vitiligo signs include: Patchy loss of skin color, which usually first appears on the hands, face, and areas around body openings and the genitals. Premature whitening or graying of the hair on your scalp, eyelashes, eyebrows or beard.
It's more visible in people with darker skin tones. Although vitiligo can develop in anyone at any age, macules or patches usually become apparent before age 30. You might be at a higher risk of developing vitiligo if you have certain autoimmune conditions like: Addison's disease.
Stress increases the levels of catecholamines, neuropeptides, and cortisol that are higher in vitiligo patients [37–39] suggesting their role in the pathogenesis of vitiligo.
Pityriasis versicolor can sometimes be confused with vitiligo, as they both cause the skin to become discoloured in patches. But there are ways to tell the difference: vitiligo often develops symmetrically (on both sides of your body at the same time), while pityriasis versicolor may not.
Segmental vitiligo is unique, even beyond the fact that it doesn't cross the midline. It spreads very quickly, faster than the other forms, but only for about 6 months (sometimes up to a year).
Topical steroids come as a cream or ointment you apply to your skin. They can sometimes stop the spread of the white patches and may restore some of your original skin colour. A topical steroid may be prescribed to adults if: you have non-segmental vitiligo on less than 10% of your body.
Treatment cannot cure vitiligo.
While researchers are looking for a cure, treatment cannot currently cure this disease. Treatment can help restore lost skin color, but the color (repigmentation) may fade over time. To keep their results, many patients have maintenance treatments.
Vitiligo is associated with other autoimmune diseases: Addison disease (disorder that occurs when the adrenal glands do not produce enough hormones) Thyroid disease. Pernicious anemia (decrease in red blood cells that occurs when the intestines cannot properly absorb vitamin B12)
If the spots are not truly white, but hypopigmented and not depigmented (they don't enhance by Wood's lamp), then they are NOT vitiligo and could be any number of different diseases and conditions.
What Are The Early Signs Of Vitiligo On Lips? In most cases, vitiligo on lips starts with small patches of discolored skin. Though these white patches can appear anywhere on your lips, it usually occurs on the lateral lower lip.
“Patients with sleep disorders may suffer the potential risk for vitiligo. Therefore, a bidirectional relationship exists between vitiligo and sleep disorders.”
Vitiligo is a common pigmentary disorder caused by the destruction of functional melanocytes. Vitamin D is an essential hormone synthesized in the skin and is responsible for skin pigmentation. Low levels of vitamin D have been observed in vitiligo patients and in patients with other autoimmune diseases.
To the best of our knowledge, vitamin D significantly affects melanocytes and keratinocytes. Studies suggest that vitamin D3 increases tyrosinase activity and melanogenesis in vitro [12], which may lead to repigmentation in vitiligo skin lesions.
Moreover, people with vitiligo lack melanin, which is the body's natural protection from the sun, so sun exposure can be particularly dangerous. That's why it's vital that people with vitiligo use broad-spectrum sun protection with an SPF (sun protection factor) of 30 and above.
Vitiligo does not pose a serious threat to one's health, but it can result in physical complications, such as eye issues, hearing problems, and sunburn. People with vitiligo also tend to be more likely to have another autoimmune disease (like thyroid disorders and some types of anemia).
Research suggests that most people who develop vitiligo do so during childhood. As you age, Dr. Mohta says untreated vitiligo often progresses to involve the surrounding skin or create new patches of discoloration.
There is no "cure" for vitiligo. Sometimes patches go away on their own. But when that doesn't happen, doctors can prescribe treatments that might help even out skin tone. Some of these treatments are things you can try at home; others are done by a doctor.
About 15 to 25 percent of people with vitiligo are also affected by at least one other autoimmune disorder, particularly autoimmune thyroid disease, rheumatoid arthritis, type 1 diabetes, psoriasis , pernicious anemia, Addison disease, systemic lupus erythematosus, celiac disease, Crohn disease, or ulcerative colitis.
Our dermatologists often diagnose vitiligo based solely on a physical examination. If doctors need more information about how the condition affects your skin cells, they may suggest a skin biopsy or blood test.
While many people feel comfortable or enjoy how vitiligo looks, it may not be comfortable for everyone with the condition. In cases of mild vitiligo, a person can camouflage the white patches with colored cosmetic creams and makeup. They should select tones that best match their own skin tone.
