In my case it's a chronic condition, but that doesn't mean it is in yours. I have what my GI doc referred to is a "reactive stomach". I had told him I thought I had chronic gastritis, but he said, no. My stomach can get better for a period of time, then get irritated, and I'm back into a gastritis.
Before my Nissen surgery it was much worse. I'd have esophagitis in addition to gastritis, which was even more painful. Now, it fortunately stays in my stomach, which is much less painful and easier to heal.
I can't answer the coffee question. It will be answered by you. In my opinion there is no universal list of things that will cause problems. It's a very individual thing. Coffee is off my list of things that can be ingested on a regular basis. I used to drink a LOT of coffee in the morning before going to work. Over time, it started bothering me. Now I do drink it occasionally...I only drink really good coffee...if I'm going to be bothered by it, I'm going to enjoy it!
I drink black tea, but drink it fairly weak. If I drink a lot of it and it's strong, even tea can bother my stomach. I don't know if you have GERD, but if you do, remember that caffeine can weaken your LES and create more reflux.
When I spoke to my GI doc, I asked him how long I should baby my stomach before eating normally again. I'd find that my stomach would feel better after a few days, then I'd eat normally/challenge it, and I'd be back to square one. He said that I should eat carefully until my stomach feels perfect for two weeks, then gradually introduce more challenging foods. It's a rule of thumb that I follow when I'm having problems.
Good luck getting things better. Be patient...it takes time!
