I think my D got started after I had an allergic reaction to sugar alcohols. Lesson number one. Secondly, I don't have a gall bladder and have bile problems to begin with, but I had been doing so well for a long time and wasn't on my bile medicine regularly when I ended up consuming the sugar alcohols. I was also getting worse about my diet and eating pizzas and fast food and things I was not used to.
Sooo... I ended up in bed for two days hurting too much to get out of it, except to go to the toliet. After two days the intense rumbling/gurgling and constant pain went away, but I was still left with pain before, during and after bowel movements and a lot of non-bile diarrhea. I eventually found this website and read about the calcium. I tried some, in addition to going back on my Welchol for excess bile (even though it didn't seem like I had my usual excess bile problem). The pain went away and so did the diarrhea. Now I take one Welchol a day and depending on what my stool was like the day before, I might also take a calcium pill to sort of boost the drying-up power of the Welchol. I found out that I can't live on calcium supplments alone!
I have read that calcium can help soothe G.I. tract irritations and I think that's what happened to me--a little too much bile going through on a regular basis, followed by an allergic reaction. Once the calcium got everything calmed down, I was able to go back to my old Welchol regimen and am fine as I have ever been since the old GB went bad.
