Vitiligo Causes

At present, the exact vitiligo causes are unknown, but there are several theories held by various scientists and medical practitioners. These range from a belief that the disease may be an autoimmune disorder, possibly genetic, or even originate from some form of emotional stress or sunburn. There are some schools of thought that believe that vitiligo is caused by a combination of these factors.

Autoimmune Disease

 

This theory suggests that vitiligo is caused by an autoimmune disease, which leads to the destruction of melanocytes by the body’s immune system. Melanocytes are the cells that produce melanin, which is responsible for skin colour. 

Heredity

Another theory supports the idea that vitiligo is hereditary. It is known to run in families, and it is feasible that specific genes may cause an immune system disorder resulting in vitiligo. As yet, these genes have not been identified.

Sunburn or Emotional Distress

Some sufferers have stated that vitiligo symptoms arise following particularly bad bouts of sunburn, and also when dealing with emotionally stressful stages of their lives. The commonly held belief is that sunburn and stress alone may not cause vitiligo, but actually instigate the symptoms in someone who may be genetically predisposed to the condition.

Although vitiligo causes are unknown, what is clearly evident is the way in which the disease manifests. The cells known as melanocytes malfunction, and the area surrounding the rogue cells gradually turns white as a result.
