In this Health & Beauty, we focus on a particular condition of the skin known as Vitiligo. It’s a condition in which some of the pigment of the skin is lost. Pigment, or melanin, is what gives your skin its colour.
Most people with vitiligo lose pigment in patches and the normal pigment becomes replaced by flat, white patches with irregular borders. This loss of pigmentation can occur in small patches on one side of the body or in large areas covering over half of the body. It is often somewhat symmetrical on the left and right sides of the body. These patches are usually areas of the body that are exposed to the sun, such as hands, face, arms and feet.
The condition isn’t contagious, doesn’t cause pain, and isn’t medically dangerous. Vitiligo affects males and females of all races equally. Vitiligo can be treated but not cured. It is estimated that about one percent of the general population has vitiligo.
What causes vitiligo
The exact cause of vitiligo is unknown, but it does appear to be an inherited condition. It’s been noted that sun damage may trigger vitiligo symptoms in some patients. Up to 30 percent of people who have vitiligo have a family member with the same condition. Links exist between vitiligo and other diseases, such alopecia, hyperthyroidism, Addison’s Disease, and pernicious anaemia.
The lining of the inside of the mouth may also lose colour. Premature greying of scalp and facial hair can also be a sign of vitiligo. This includes even the eyebrows and eyelashes.
Diagnosing vitiligo
Your doctor will review your medical history and possibly test a skin sample to diagnose vitiligo. A skin biopsy can reveal the complete absence of pigment and may confirm the diagnosis. Your doctor might also run blood tests to check your vitamin B-12 levels and thyroid function. An overactive thyroid and a deficiency of B-12 are often associated with vitiligo. Running these tests can help you get prompt treatment for any related conditions, if needed.
