I have been having bloating, continuous burping, fullness upper abdomen and burning chest sometimes. I did endoscopy a week ago and doctor diagnosed mild gastritis. He said it could be because of health anxiety and stress related. I do have sedentary lifestyle as I am working from home and I do have health anxiety, but I did not know I would end up messing up my stomach. I am on nexpro, a combination of domperidone-30 mg + esomeprazole-40 mg twice a day and I have changed my diet to completely bland and boil. Eating veggies and fruits. However symptoms are pretty much the same my question is that doctor did not consider testing for autoimmune disease or h pylori. He said h pylori bacteria are not seen in endoscopy and hence no test required. If that's the case then why do I have inflammation in stomach. Should I insist on getting tested for h pylori? What is causing these symptoms if the case is mild and why it has not been improved? P.s I had severe case of acute gastritis 8 months ago and after my vit b12 dropped to 112 pg/ml. I took injections and got it to 400 pg/ml. Is this a case of pernicious anemia?
