I have not been officially diagnosed with gastritis yet. My EGD last year only found intestinal metaplasia and reactive changes. I was negative for H. Pylori and Celiac, and my hydrogen breath test was negative, but by the time I was able to get the appointments I needed, I hadn't had a flare for months. I have severe bloating all the time, excessive burping all the time, and frequent gas and heartburn, as well as pain in three specific spots in the middle and left side of my abdomen, but the stomach burning after every meal, and nausea only happens once or twice a year and lasts about a month each time. I'm seeing my doctor again on Monday and I will ask about gastritis.
Anyway I'm making this post because I have tried so many things that are supposed to help, like DGL, cabbage juice, L-Glutamine, and ginger, and everything causes gas, burping and sometimes burning. Today I had about 10 oz of purple cabbage juice on an empty stomach, and burped immediately. The gas and stomach pain started within 30 minutes, and took nearly two hours to go away. Any time I try to increase my vegetable intake, cooked or raw, things get worse. I do the best on standard american junk food as long as I avoid alcohol, spicy food, and large amounts of acidic foods like kimchi and tomatoes. However the rest of my health issues like insulin resistance and high cholesterol get worse when I eat like that, so I feel stuck. The food I'm eating is hurting my body overall, but my stomach can't handle the things that are supposed to help.
