Re: Habba Syndrome
That cholestyramine powder is gross, isn't it? Depending on brand, you may find one that's less gritty - the stuff I was given while in the hospital didn't seem to dissolve at all. The stuff I got from the pharmacy is finer and dissolves... mostly. Mixing it with juice, gatorade, or something else fruit flavored helps make it a bit more palatable.
I could have sworn there was a pill/capsule, but I'm not sure.
I heard of Habba Syndrome a couple years ago. Before I had my gallbladder out I had a lot of diarrhea problems, now that it's out... well it still happens some but that has always gone through phases so I don't know if it will stop for me. My GI doc suggested I start taking fiber to help.
I'm really surprised your doctors could never figure this out. It's not uncommon for those who have their gallbladders out (search past threads on here, for example) or even still have their gallbladders but have something wrong with them.
After 12 years... I think you're stuck with it. Have you noticed any patterns with foods? Some will still cause me diarrhea (too bad, too, I really like the food at an Italian restaurant in town - too much butter and oil in the food, though).
Keep an eye on your electrolytes and vitamin levels. If you get diarrhea fairly often they can drop in no time.
