The healthcare provider will ask about your medical history, family history of vitiligo or autoimmune disorders, and whether you have experienced any recent illnesses, stress, or skin trauma that might be related to the onset of depigmentation.

Diagnosing vitiligo involves a combination of medical history, physical examination, and specialized tests to confirm the presence of depigmented patches on the skin. A dermatologist typically conducts the diagnosis, focusing on the unique characteristics of vitiligo and ruling out other conditions that might cause similar symptoms.
