thanks for trusting Healthcaremagic. What you are suffering from doesnt sound to me like Bulimia
, as bulimia, on the contrary is binging/ increased and abnormal eating, which you of course do not have. You got loss of apetite and this is a symptom common with lot of pathologies.Could be some gastrointestinal problem, could be some respiratory problem even. So i would suggest you get few baseline blood tests done and of course you need to consult with a physician along with the reports.
