Is vitiligo contagious

summary

Vitiligo is a common skin disease, but the treatment of vitiligo is more difficult. Now many people suffer from vitiligo. My cousin is a patient with vitiligo, with several white plaques on her arm. Many patients with vitiligo want to know whether vitiligo can be infected.

Is vitiligo contagious

First of all: vitiligo is not contagious, but has a certain genetic probability, the depth of human skin color, black and white are often affected by seasonal changes. Sun exposure in summer and sunbathing after swimming all cause skin color to deepen. Sunlight contains ultraviolet rays, which can stimulate the activity of enzymes, accelerate the transformation of tyrosine into DOPA and DOPA quinone, and promote the formation of melanin in the process of melanin metabolism.

secondly. The good and bad mood brings different results to the disease. Most of the patients with vitiligo are depressed, pessimistic, disappointed and worried. There are also some people who are afraid of the development of the disease, which will affect the beauty of their face and lead a life of weariness. Tension affects the formation of melanin, because tension stimulates the secretion of epinephrine, the synthesis of epinephrine, also need tyrosine. The loss of tyrosine will affect the synthesis of melanin.

Finally: diet is also the cause of vitiligo. Relevant studies have confirmed that the lack of trace elements such as copper, zinc and iron in the human body can reduce the activity of tyrosinase and affect the metabolism of melanin.

matters needing attention

The deficiency of some trace elements in vitiligo patients leads to the disorder of melanin metabolism. Therefore, patients with vitiligo should eat foods rich in tyrosine and minerals, such as meat, eggs, pig liver, peanuts, walnuts and black sesame.
