The most important thing is to maintain an optimistic state of mind, to understand that this is a normal phenomenon, and to avoid bad emotions such as tension and anxiety, so that the body’s neurological functions do not become disturbed. The functions of the gallbladder are as follows: storage of bile: after the liver secretes bile, a small amount of bile enters the gallbladder and contracts when needed to discharge the stored bile into the intestine; concentration function: the bile that enters the gallbladder is partially absorbed in the water in the gallbladder, making the bile in the gallbladder more concentrated, thus playing a concentrated role; excretion function: when people eat, the gallbladder contracts and the bile in the gallbladder is discharged into the intestine, playing Secretory function: the mucosa of the gallbladder still has the role of secreting a little mucus, which is also involved in the composition of bile. These functions are normal only if the gallbladder is good, and they are also abnormal if the gallbladder is faulty. Secondly, patients who experience diarrhea after cholecystectomy can be treated by adjusting their diet. At the beginning of the diet adjustment, patients can eat some easily digestible liquid food or semi-liquid food first, and then gradually change from eating semi-liquid food to eating normal food. When eating ordinary food, patients should pay attention to eat less greasy food, eat less and more meals, eat regularly and quantitatively to reduce the burden of the digestive system, and at the same time should try to choose more foods rich in dietary fiber and vitamins, such as fresh fruits and vegetables; avoid fatty, fried and other foods with high fat content. Again, general antidiarrheal medications such as Simethicone, compound phenylephrine, and Emmenagogue can be taken under the guidance of a doctor. Finally, this kind of diarrhea mostly appears within 3-6 months after surgery, and most patients’ diarrhea symptoms will be significantly improved after a period of recuperation. This may be due to the fact that the common bile duct will gradually compensate for the dilation after gallbladder removal, replacing part of the function of the gallbladder.
