What are the main things responsible for causing vitiligo??
Doctors and scientists have several theories as to what causes vitiligo. The basic mechanisms currently proposed are: 1) the melanocytes (pigment cells) are destroyed by other cells from the immune system (system of defense) of the individual, 2) the melanocytes are destroyed by internal biochemical reactions that occur while the melanocytes are making pigment, which results in the death of the cells, and 3) the nerves in the skin produce signals that destroy the melanocytes. In all cases, one or more of these mechanisms may act together to produce vitiligo. Some of the available medical treatments attempt to stop each of these mechanisms. Other treatments try to stimulate the division and movement of existing melanocytes into depigmented areas.
