White Patches
What is Vitiligo?
Vitiligo is a skin condition that results in patches in areas of skin losing their pigment. It occurs when cells that produce pigmented skin, known as melanocytes, a cell that produces and contains the pigment called melanin, are destroyed or no longer function. These white patches or spots can occur anywhere on the body, on your face, hands, arms, feet, and even inside your mouth.
Vitiligo can occur in anyone of any normal skin color, but it is more prominent in people with darker skin tone. It is not contagious or life-threatening, but it can cause considerable emotional stress and increased risk of anxiety. Most people with vitiligo face some struggle with self confidence, particularly if the spots are visible.
Types of vitiligo:
- Universal vitiligo: This type creates the discolouration on almost all the skin areas, affecting skin all over the body.
- Generalized vitiligo: It is also called nonsegmental vitiligo and is the typical form of vitiligo skin diseases, in which symmetrical patches can be found on opposite areas of the body and have a similar manner of spreading.
- Segmental vitiligo: This form usually begins at a younger age, involves only one side or area of the body, and progresses for one to two years before stabilising.
- Localized (focal) vitiligo: Here only some part or a single part of the body is involved.
- Acrofacial vitiligo: This kind of skin disorders affect the face and hands, especially skin around body openings such as the eyes, nose and ears.
