summary

My friend is suffering from vitiligo this disease, arm long several white plaques, recently went to the hospital for treatment, the doctor in the treatment also told us about the cause of vitiligo, now I will tell you about the cause of vitiligo.

What is the cause of vitiligo

Cause 1: the depth of 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.

Cause 2: the good and bad mood brings different results to the disease. Most 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.

Etiology 3: 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 patients with vitiligo should have a persistent attitude to face and treat this disease. The deficiency of some trace elements in the body of patients with vitiligo 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.
