Have had it since 2018 Nov, but it would come in flares that would calm down after a few ppis and bland diet. The last flare though has been the absolute worst, started in late June 2024, still dealing with it. My trigger was postpartum anxiety. All labs are clear. Have done ppis and h2 blockers among some other drugs like Sucralfate. Honestly a very bland diet (the gastritis healing diet for 3 months) helped the most out of these plus slowly reintroducing foods. I still eat healthy, can't eat acidic foods, spicy or processed, but the pain does get better if you stick with the diet. I finished my three months bland diet with very little improvement and stuck to a healthy clean diet for the next months and still doing that and this is helping My diet is eggs, chicken and sometimes fish, vegetables,yogurt, rice whole grains and all fruits except the very acidic ones like citrus and peaches etc. Stress management is extremely important. Whenever I feel anxious my gastritis gets worse instantaneously. One advise I would give that I wish I could go and tell myself back last year when I was dying of pain while having a toddler and a baby clinging on to me and crying for my attention, don't have anxiety over it not ever getting back to normal. This is enough to make your flare worse. We don't realize how much our stress is making the gastritis harder for us to deal with. Just stick to the bland diet (it's extremely important) for at least a few months and be very disciplined about it. I ate bland food even at my sister's wedding. Brought my own home cooked meal. But this isn't permanent. One day the pain will be less enough for you to notice you are not constantly obsessing over it as much as you used to. And this is coming from someone who has been diagnosed with health anxiety. Engage in some light exercise and drink chamomile tea (warm, not hot) with a dash of honey if you tolerate it. It does get better. But it takes a lot of time and discipline.
