I had my gallbladder surgery 18 years ago and within a week or two after the surgery, I started to have diarrhea(?sp), and have had diarrhea ever since, non-stop! I have tried prescription drugs, over-the-counter drugs, nothing has worked. I was tested by different doctors, they say they can't find a thing wrong. I have diarrhea all the time, but I have at times also been constipated, one time serious enough to see a doctor. Of course, everytime they say it is "viral", but I know better.I have been told by a few doctors that I had Irritable Bowel Syndrome, even though I don't remember being officially tested for this. I have all the symptoms/problems of IBS though and consider this to be the situation.But, I had not heard of this other deal listed above and need to do some checking into that. Maybe this is what I really have, not IBS. Who knows? All I know, I have had this for 18 years now, non-stop, and it mainly gets worse after meals, but can, and does, hit me at anytime it feels like hitting.Before I had gallbladder removed, I never had one single problem, and to be honest, I don't remember being either constipated, or having any diarrhea, I just remember being in major pain, especially after eating certain foods! I would be up half the night looking for something that would make me sleepy, etc....just so I could get some rest. When I finally saw the doctor and found out that it was my gallbladder, the doctor gave me some pain pills to take until I could have the surgery. Thank goodness!! I had one stone the size of a quarter, and two or three more the size of a dime, or larger.
