What is Vitiligo ?


Vitiligo is a condition in which the skin loses color in patches. It can be seen in people of any ethnic group, age or gender.

Melanocytes  are responsible for the skin’s color and protection from the sun’s UV rays. When the cells containing melanin, called melanocytes, die, the skin becomes patchy and white in certain areas.  The discoloration might be seen in the mouth, eyes, and hair. The discoloration is usually permanent. People with dark skin tend to show more light patches due to their skin color.

Types of vitiligo


There are two types of vitiligo: segmental and non-segmental.

Segmental vitiligo

Segmental vitiligo is characterized by rapid spreading but has more stability. Segmental vitiligo affects the areas of skin which are attached to nerves. The condition can be treated well through topical treatments.

Non-segmental vitiligo

It is the most common type of vitiligo as it accounts for nearly 90 per cent of the cases. The patches appear symmetrically.

Symptoms


The appearance of flat white patches on the skin is the only symptom of vitiligo. The spots appear mainly in the exposed areas. It starts as a simple pale spot, but with time it progresses to white color.

The patches are irregular and sometimes show a slightly reddish color. The person may experience itchiness in these areas. They usually do not cause any discomfort, soreness, or dryness in the skin. The pattern of development in different patients is also quite different. While some people may see the development of only a few spots, some people may see the development of a large spot that goes on progressing.

Causes


Though the exact causes of vitiligo are unclear, there are several factors which may trigger the condition –

  • An overactive immune system which starts destroying the melanocytes.
  • Stress
  • Critical sunburn or cutting of the skin 
  • Exposure to certain  chemicals
  • Heredity
  • Virus 
  • Imbalance in the genetic oxidative factors 
  • A neural problem 

Vitiligo is not a contagious disease; it can’t be passed from one person to another person. Though it can occur at any age, it is commonly known to strike at the age of 20 years.
