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.
