Thanks for filling in some of the details. I am not familiar with the use of colestipol to manage a removed/damaged gall bladder but this is certainly one of its legitimate uses. To what extent have you played around with dose and timing of the medication? Generally speaking, people have most success with it when taken with the meals that contain the most fats, and usually no sooner than the first bite of food but some find it more effective up to 45 minutes after eating concludes. If you have not already, consider diligently tracking what and when you eat, and when you took colestipol, and see if you can at least move the needle towards something better than your current situation. Last, have you spoken to your doctor about these symptoms? He or she may have some advice on things that we have overlooked. Good luck.
