Hi,
Vitiligo is caused by lack of pigment called melanin in skin. In vitiligo, there are not enough working melanocytes to produce enough melanin in your skin. Vitiligo may result from autoimmune conditions like
hyperthyroidism, Addison's disease, DM,
melanoma, non-Hodgkin's
lymphoma, genetic factors etc. Treatment depends on its causes.
You should undergo some investigations like CBC, thyroid function test, RBS, S.
cortisol, ACTH, biopsy from the affected skin area etc., to find out the underlying the causes which are responsible for your vitiligo and then treat them accordingly. In the meantime, you can use steroid cream on your affected skin to restore some pigment, sunscreen to avoid sunburn, Tacrolimus topical ointment on your affected skin.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Zubayer Alam, General & Family Physician
