Hi, postcholecystectomy syndrome (PCS), occurs after removal of the gall bladder. PCS is caused by alterations in bile flow due to the loss of the reservoir function of the gallbladder. Two types of problems may arise. The first problem is continuously increased bile flow into the upper GI tract, which may contribute to gastritis. The second consequence is related to the lower GI tract, where diarrhea and colicky lower abdominal pain can occur as the bile is continuously secreted. But this will settle with time. Regards.
