Frequent diarrhea is related to bile production. Bile can play a role in the digestion and absorption of fat as well as the absorption of fat-soluble vitamins, etc. If there is insufficient bile secretion or excessive fat intake, it may lead to fat indigestion, which may lead to steatorrhea and diarrhea. In addition, after cholecystectomy, the bile can not be concentrated and stored, but directly into the intestinal tract, the intestinal tract can be stimulated by bile, intestinal peristalsis may increase, which in turn causes diarrhea, generally referred to as bilious diarrhea. Patients with frequent diarrhea are advised to go to the hospital and ask the doctor to make a comprehensive judgment based on their own situation, and should not make blind judgments on their own.
