I was hospitalized a week ago after continually suffering from severe bowel spasms, nausea, abdominal cramps, bloating, loss of appetite.......they did a colonoscopy and said everything looked okay, but took biopsies to check for celiac, etc. Since Wednesday, I've been trying to reintroduce food into my body, staying off gluten and dairy, just in case, but now I'm worse than I was before! The doctors said my problem is probably chronic constipation and I should eat more fibre, but my stomach won't seem to tolerate any food. Today I had a lactose intolerance test and I felt fine during the test, but when I got home I tried eating a gluten-free banana muffin and then had severe stomach pain and felt an urgent need to go, but even though there was lots of mushy stool, I couldn't push it out and had to disimpact myself to get it out. It was mainly undigested food and long reddish/purple thick strings, which I'm worried may be blood. Then a few hours later I got diarrhea and I finally caved and took 2 immodium, but my stomach is still killing me. I've always been IBS-C predominant, so now I'm worried that I'm swinging the other way or that they damaged something during the colonoscopy. I had stool tests done about a month ago and they were negative, but should I have them done again to make sure I don't have an infection or bacteria? I don't know what to eat or drink that won't bother my stomach, so I'm going to try some Resource meal replacement drinks, which they gave me in the hospital, but they contain whey, so I'm worried that that might be an irritant, too, but all the other meal replacement drinks have some kind of milk in them and I'm trying to avoid dairy right now. I'm also thinking of trying baby food, but I want to be able to eat again like a normal person and I have no idea where to start! Right now I'm scared to eat anything because my body seems to reject everything. I'm also thinking of trying pelvic muscle therapy to try to retrain my bowels, since I think they're so used to not having to work from me disimpacting myself, that they've become really weak. Does anyone have any other suggestions on what I should do to try to retrain my body. Any advice would be appreciated.
