Before treating vitiligo, a detailed medical evaluation is needed to understand the patient's personal medical history, family history, careful skin examination, evaluate the stage of the disease's progression, and estimate the future development of the disease. As mentioned earlier, the cause of vitiligo is attributed 80% to genes and 20% to environmental factors. Both congenital and acquired reasons for the imbalance of the autoimmune system exist; some vitiligo patients also have other autoimmune diseases, thyroid diseases, etc. Patients should have blood tests to determine whether they have other autoimmune diseases; female patients, patients with a longer disease duration, and patients with a larger body surface area of vitiligo should also test for thyroid peroxidase antibodies and regularly measure thyroid-stimulating hormone levels.<\/span>

Patients with vitiligo related to environmental factors can improve their condition by avoiding external triggering stress sources. For example, patients with Koebner\u2019s phenomenon should avoid excessive pressure (mechanical stress avoidance) on the affected areas (skin\/joints\/muscles), carefully choose personal hygiene products, clothing (looseness\/material\/contact surface), occupational needs (contact with chemicals), etc.<\/span><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>
The detailed items of doctor's evaluation include<\/span><\/strong>

Medical history<\/strong>
For example: personal medical history, family history, age of disease onset, earliest location of onset, speed of disease progression, the progress of vitiligo in the past 6 months, whether there has been any repigmentation of the vitiligo, whether vitiligo has appeared on scars, any associated stress triggers, presence of itching, whether the disease has affected the genital area, occupational history, the possibility of contact with chemical triggers, history of thyroid disease, whether blood tests have shown the presence of thyroid autoantibodies, whether family members have had premature graying of hair, past treatments received, other autoimmune diseases, etc.<\/span>

Clinical assessment<\/strong>
For example: skin pigmentation type (Fitzpatrick\u2019s skin type), freckles on the body, the following clinical assessment of the shape\/pattern\/level of vitiligo (Vitiligo Signs of Activity Score, VSAS) ... etc.<\/span>

Psychological assessment and counseling<\/strong>
For example: personal mental condition, understanding of vitiligo, patient's understanding of the current severity of vitiligo, the impact on quality of life, psychological\/social stress... etc. The patient's understanding, patience, persistence, and cooperation are especially important in the treatment journey.<\/span><\/p>
