Hi. Greetings. No tests can be performed to cure your condition. Your stomach inflammation seems to be unclear ?! Reply in detail on private follow up chat. if anything you may get a stool routine test,
vitamin b 12 levels and
thyroid tests. Alopecia areata can be recurrent. If u are getting many new patched you may need oral medication. See a dermatologist near you as they'll be the best judges of what to do next. Or send in pics with detailed history. Dr Govind Suresh Mittal, Bangalore
