What is Vitiligo?
Vitiligo is a disease of the skin and hair where the individual suffering from the disease looses the skin colour and stars developing white patces on the body. It is also known as Shwetkushtha, leucoderma and white patches.
The normal colour of human skin is determined by melanin pigment produced by cells called melanocytes, to some extent haemoglobin and carotenoids in the skin add to the colour of the skin.
Absence of melanin pigment causes vitiligo (Safed Dag). The causes of vitiligo are destruction of melanocytes by oxidative stress, cell death due to autoantibodies and toxins produced at nerve endings causing death of melanocytes.
The disease is usually slowly progressive depending on the type of vitiligo. Vitiligo can be generalised or localised, five variants of vitiligo are well known localised few patches, Segmental affecting only one segment of the body on the right or left side. Generalised affecting more than 50% of body area, acrofacial affecting only the hands, feet & the lips and universal affecting whole body.
Though the disease per se doesn’t cause any physical discomfort the person suffering from Vitiligo experience unwanted attention, stigmatisation, rejection and bullying.
There is deep rooted social bias about vitiligo, irrespective of age, sex and educational status. Women face the burden of stigma more as compared to men, since it felt they may pass it to the progeny, with serious consequences as far as marriage prospects are concerned.
