What Causes Excessive Hunger After Taking Antibiotics For Acid Reflux?

Hello I have always had acid reflux however last week when I started taking an antibiotic it seemed that I began to have increased hunger with my antibiotic. The antiobotic is finished however I have started to experience major hunger even after I eat. Does this sound like an ulcer? my reflux seems to come back when I don t exercise. I can t go on feeling this constant hunger. what can I do ??? is it any help that I can seek??
