How to Identify the Triggers of Vitiligo?

Causes of Vitiligo

Vitiligo has many causes, commonly including genetic factors, neuropsychiatric factors, endocrine factors, etc. If you want to determine the specific cause, it is recommended to visit the hospital for a Wood's lamp examination, skin CT examination, and blood routine examination under the guidance of a doctor.

General Considerations:

1. Genetic factors: Vitiligo has a certain degree of familial clustering. If both parents or one parent suffers from this disease, the probability of their children developing it will increase.
2. Neuropsychiatric factors: Being in a state of constant tension or excessive stress may lead to endocrine imbalance in the body, affecting the synthesis of melanocytes and subsequently triggering vitiligo.
3. Endocrine factors: Some patients with vitiligo may be related to autoimmune dysfunction, such as hyperthyroidism, diabetes, etc. Abnormal changes in hormone levels in the body can also affect melanin metabolism, leading to vitiligo.

Laboratory Tests:

1. Wood's lamp examination: Under light irradiation, a bright white fluorescence can be observed at the lesion site, which is helpful for diagnosis.
2. Skin CT examination: This examination can determine the specific condition of the white spot area and detect whether there is melanin loss, which is helpful for confirming the diagnosis of vitiligo.
3. Blood routine examination: Usually, blood tests are required to understand whether the various indicators in the blood are normal. Conditions such as anemia may also affect melanin production and induce vitiligo. Tissue pathological examination can also be performed under the guidance of a doctor to confirm the diagnosis.

After confirmation, drug treatment can be used under the guidance of a doctor, commonly including tacrolimus ointment, calcipotriol ointment, etc.
