Demari, I was just talking to my mother this weekend about
when she had her gall bladder out. It sounds like you may have a similar experience to hers. She had hers removed laproscopically, but it was very badly infected when she had it removed and the infection ended up spreading everywhere, including to her incisions. She said she was on antibiotics for a month and it took that long before she could go back to work (whereas mine wasn't infected and I was able to go back to work after a week, which is standard).
I agree you need to be on some probiotics while on antibiotics. The antibiotics alone frequently cause diarrhea. Throw your bile in on top of that and I feel for you! (Been there, done that.)
If you're not accustomed to taking probiotics, you may have to ease into them, the way you have to gradually introduce fiber. I think about the only side effect of probiotics is gas, but, like fiber, you tend to adjust to it and stop having it after a week or two. If you can tolerate dairy, I might start out with an Activia yogurt twice a day for a week or two, then work up to one of the pills--they tend to have a lot more probiotics in them and, thus, are stronger and more likely to give you gas. Culturelle will keep me from getting D while I'm on antibiotics (and can be found in most any U.S. chain drug store), but it gives me pretty bad gas and some gas pains. I typically take it right before bed so I can sleep through most of the gas; I only have a bit leftover when I get up in the morning. I take it while I'm on an antibiotic, then I eat an Activia yogurt everyday for three weeks afterwards and then I'm good.
I did a low-fat diet for four or five months. Yes, I quit having bile diarrhea. In fact, I quit pooping and had terrible constipation; I have had my gall bladder out 6 years this February and I don't have a happy medium naturally. If I take calcium and Welchol, I can tolerate most things (still no caffeine, no deep-fried foods except every great once in a while and in a small amount, no apple juice) and not have bowel problems or gas pains. But without those meds, I can't control my digestive tract with diet alone; I either have D or C, nothing in between.
Someone else mentioned that fiber didn't work for them; it doesn't work for me either. I took a fiber pill supplement and it made both my D worse and my C worse! Of course, there are a lot of fiber products on the market, and not all of them work the same. Still, I had such a bad reaction both times I tried those fiber pills I'm too afraid to try anything else; either I get fiber from my food or I don't.
