Have been diagnosed with Vitiligo? Or someone close to you has been affected with this skin condition? Before you look for some cures and treatments, it is important you learn about the major symptoms and causes. Here is something useful. Read on.

Symptoms of Vitiligo

In the last post, it was discussed about the skin depigmentation condition, vitiligo. Although the causes were discussed their in brief, here is the detailed information to help you find the best cure. Unless you are known to the causes and signs, you will not be able to treat it properly. So, here you go;

What are the symptoms of vitiligo?

The very first sign would be the white patches (depigmentation) on the skin. Being the foremost symbol, the patches are highly common to sun-exposed areas. It can be your feet, arms, hands, face, and lips.

But that’s not all! There are other common areas such as skin around the mouth, eyes, nostrils, navel, armpits, groin, genitals, etc. which can be affected.

Basically, it appears in one of three patterns, focal pattern, segmental pattern and generalized pattern namely.

  • Focal pattern: In this case the depigmentation is limited to one or only a few areas.
  • Segmental pattern: The depigmentation patches develop on only one side of the body.
  • Generalized pattern: If the depigmentation occurs on different parts of the body, it is generalized.

Now, the question most vitiligo patients ask- are there any specific causes for vitiligo? Well, the answer to this depends on whom you ask. While most experts agree on the fact that there is really no reason know for vitiligo, but few will give you a variety of reasons too.

Scientific Theories:

In all there are three possible theories associated with vitiligo. Have a sneak peek at them in detail;

Autoimmune: As per the autoimmune hypothesis when immune system starts attacking the melanocytes (special skin cells), the problem occurs. Actually, these special skin cells are responsible for producing melanin and when the melanocytes are depleted, skin start losing pigment.

Neural: This theory states simply that the chemicals such as norepinephrine are responsible for destroying melanocytes. The reason being, norepinephrine is toxic to melanocytes and it is this toxicity which further prevents the production of melanin. Hence, it eliminates pigmentation from your skin.

Autocytoxic: Do you know about the autocytoxic reaction? Researchers believe that the process of melanin biosynthesis produces a toxic substance which then causes damage. And when the damage takes place it reduced the melanin production, further leading to pigment loss.

As far as the truth behind the theories is considered, these are based on research and evidence gathered from different patients. And hence, it is important to mention that these are not only the possible causes for vitiligo. There are many other factors they are not aware of.
