I feel somewhat bad replying to an old post like this, (and really that as a whole is why, while I have browsed before I've never really posted on uboachan much) but, if you are here anon, what are the symptoms of your stomach infection and gastrointestinal issues? I thought that I might have IBS, and brought it up with my doctor last year. but I don't really eat much of the things that apparently cause IBS symptoms anyways, so, I've wondered if the issue is something else. It also feels like when I'll get cramps and diarrhea is completely random. I can eat fast food garbage and feel fine, but eat a home cooked meal and feel horrible after (although I think milk and coffee will pretty consistently make me sick). I've done blood tests for celiac and didn't have that. When I do have my episodes of cramps and diarrhea, my shit will have an "infection" sort of a smell for lack of a better term, normally it doesn't smell like that, only when I have an episode, which also makes me think it might not be IBS, but instead an infection or some other gastrointestinal issue. These bouts of cramps and diarrhea happen probably around once a week, every two at the most, so it's not an everyday thing, but when it does happen it lasts quite a long time. Maybe it really is just IBS and I'm being stupid about it.
If you did end up getting a colonoscopy and more bloodwork, I'd be curious to know how it went. I get you're not a doctor, but, maybe you'd have some sort of an idea of what might be wrong if my experinces are similar to yours.
I'm sorry for the long-winded post, and if other people with gastrointestinal issues want to chime in, by all means do so.
