General information, not an individual diagnosis. Ask a healthcare professional if you are unsure about your situation.
A newly white area may suggest vitiligo, but other conditions also lighten skin. Arrange an examination of these changes.
Your doctor may refer you to a dermatologist. A Wood lamp helps distinguish complete pigment loss from other causes.
After diagnosis, the doctor checks for associated illness when appropriate. Whether blood tests are needed depends on this assessment.
Unless your clinician gives specific instructions, seek shade, cover skin and use SPF 50 sunscreen. Depigmented areas burn easily.
Avoid repeated rubbing of affected patches. Tell your doctor promptly about a new patch or a reaction to treatment.
Prepare questions about the patches and bring previous results. Ask your dermatologist for a follow-up schedule and individual sun-protection instructions.
