I have the same problem after my gallbladder was removed (for about 7yrs! now). Most of the time this affects me during my sleeping hours, which include great pains in my left to middle/stomach and sometimes in my back and colon. The pain is so great a lot of times that I get lightheaded and nauseas.
I found that if I eat something right away or throw up, the pain will go away. After I eat I have release of gas and several "small" bowel movements during the day.
As a result of early A.M. eating and drained energy, I've gained a great amount of weight...prior to this I was thin, energetic and health conscious.
The doctors have told me that I have a slow digestion of 30% apposed to 100%, with no explaination. There has been no magic pill to heal this problem and no relief up to this point for my misery. I feel trapped and I want to live a normal life again for myself and my family-NOT THROWING IN THE TOWEL YET!!
Does anyone else have these symptoms?
