The functions of the normal gallbladder are mainly bile storage, bile concentration, secretion (some mucus) function, and contraction function, which means that the gallbladder is able to store and concentrate the bile that is not normally used, and after eating (especially after eating more fat), through contraction, but the concentrated bile is discharged into the intestine to help digestion. Therefore, the gallbladder has its own function. Therefore, the gallbladder should never be removed easily, meaning that cholecystectomy should have clear indications, and only after careful study, when it is determined that the gallbladder is no longer functional, or when it is believed that keeping a diseased or stone gallbladder is more harmful to the patient than the benefits of the gallbladder’s physiological function to the body, should one go for cholecystectomy. After removal of the gallbladder, due to the loss of the gallbladder’s function of storing bile, the digestive function of the person will be affected to a certain extent for a short period of time (such as the appearance of mild diarrhea, indigestion, abdominal pain, bloating and other symptoms), but the effect is not significant. The vast majority of patients will gradually adapt to it and will not feel any abnormalities, which will slowly disappear with the passage of time. From the clinical point of view, those with mild or even no symptoms of gallbladder stones before surgery, as well as those with basically normal gallbladder function before surgery, are prone to such digestive malfunction after surgery; while those with heavy symptoms before surgery and whose gallbladder has lost its normal function, their digestive function will in turn improve after surgery.
