2. Autoimmune diseases: such as hyperthyroidism, diabetes, etc., patients with these diseases are prone to vitiligo.

3. Neuropsychiatric factors: people who have been in a state of tension for a long time, such as anxiety, depression and other emotional instability, are prone to induce the disease.

4. Melanocyte self-destruction theory: It is believed that melanocytes are destroyed by some unknown factors, resulting in a decrease in melanogenesis and disease.

5. Relative deficiency of tyrosine and copper ions: due to the lack of these two elements in the body, the normal function of the enzyme system in melanocytes is affected, and the synthesis of melanocytes is disordered.

2. Performance

Vitiligo lesions are milky white or porcelain-white pigmented completely depleted spots, with clear borders, scattered pores-like small black spots at the edges, often distributed everywhere, can be unilateral or symmetrical, vary in size, different shapes, and unclear boundaries with the surrounding normal tissues. In rare cases, there will be white hair follicles in the white patches, and the number of white patches is indefinite, which can be confined to a certain part of the body or spread all over the body. Most patients are asymptomatic, and a few experience mild itching after the disease.

Patients are advised to seek medical treatment in a timely manner to avoid delaying the condition. Usually pay attention to avoid sun exposure and ultraviolet rays, and eat more foods rich in vitamin C, such as kiwi fruit, tomatoes, etc.
