Is vitiligo hereditary

summary

Got vitiligo, in the treatment, good care, at least to ensure that vitiligo will not spread. In order to prevent this problem, let me introduce the genetic probability of vitiligo.

Is vitiligo hereditary

First, the theory of heredity. Vitiligo can appear in twins and families, indicating that heredity plays an important role in the pathogenesis of vitiligo. Studies have shown that vitiligo has incomplete penetrance and multiple pathogenic loci. The decrease of copper or ceruloplasmin levels in the blood and skin of patients with vitiligo leads to the decrease of tyrosinase activity, which affects the metabolism of melanin.

Second: vitiligo can be combined with autoimmune diseases, such as thyroid disease, diabetes, chronic adrenal insufficiency, pernicious anemia, rheumatoid arthritis, malignant melanoma and so on. The specific antibodies of various organs can also be detected in serum, such as anti thyroid antibody, anti gastric parietal cell antibody, anti adrenal antibody, anti parathyroid antibody, anti smooth muscle antibody, anti melanocyte antibody, etc.

Third: mental factors are closely related to the onset of vitiligo. Most patients have mental trauma, excessive tension, depression or depression at the onset or skin lesion development stage. The degeneration of nerve endings in leukoplakia also supports the neurochemical theory. Trauma, sun exposure and some photosensitive drugs can also induce vitiligo.

matters needing attention

Vitiligo patients are not unable to see the sun, is to try to rare the sun, especially in the sun is particularly big, try to go out, should try to avoid skin damage, there are many patients with skin injury after vitiligo; some whitening cosmetics should be less or not. You should also avoid sun exposure, especially at noon. Vitiligo in the face and hands should be less sun.
