The nature and severity of vitiligo may vary from person to person. Sometimes, its symptoms appear on a certain spot of the skin which might spread out to the other areas sooner or later. In some cases, it has also been observed that the vitiligo remains unchanged and the effected person does not notice new patches at all for many years, but it abruptly spreads to the other areas of the skin later. In other cases, it keeps on growing in size and affecting the other skin spots. However, it might be a slow process and a proper treatment and care can stop or at lest slower down this process.
There are different types of this disease because of their course & severity, but it is usually divided into two major types which are known as segmental and non-segmental.
This type is also known as localized or unilateral vitiligo and it usually appears on a certain spot of the skin. It normally affects the areas that are attached with spinal cord’s dorsal roots. Though, it is not very common, it suddenly attacks other spots of skin.
This sort of this disease also known as generalized or bilateral vitiligo and it usually appears on various parts of the body. The effected person notices that his/her disease occurs bilaterally as the symptoms appear on both side of the effected area such as both elbows or both knees.
Some More Types
Focal or Areata Vitiligo
It is considered a different type as in this condition white patches appear in small number and on various body areas.
Acrofacial or Acral Vitiligo
It is another type in which the symptom of vitiligo appears in form of losing color of skin on certain places such as face, toes, fingers etc.
It is considered to the most disturbing type of vitiligo as in this condition, the entire skin area gets depigmented. However, it is not very common.
It is a threat for those who have dark skin color. Depigmented areas coexist with hypopigmented and with normal skin color.
