First of all, the tolerance of various foods and the amount of one diet is different for different patients and cannot be generalized. Generally speaking, the digestive function is affected by the recent loss of the gallbladder, which stores bile, after gallbladder removal. The bile produced by the human liver is discharged into the intestine and has the function of digesting fat in food. Under normal circumstances, most of the bile produced at night or between meals is concentrated and stored in the gallbladder, which contracts during meals and discharges the concentrated, highly digestible bile into the intestine to digest food. After the gallbladder is removed, the bile produced by the liver cannot be discharged into the intestine on time according to the body’s need to eat, but continuously, thus affecting food digestion, which can manifest clinically as diarrhea. Due to the irregular discharge of bile, the bile entering the intestine may also flow back into the stomach and cause bile reflux gastritis. However, the human body has a strong adaptive ability to replace the function of the gallbladder by thickening the common bile duct after losing the storage and concentration function of the gallbladder, which explains why the common bile duct is dilated after gallbladder removal. Therefore, it is necessary to control the diet appropriately in the near future after gallbladder removal. Within 7 days after surgery, Tian Mingguo, Department of Hepatobiliary Surgery, People’s Hospital of Ningxia Hui Autonomous Region: abstain from high-protein and high-fat foods, especially not eggs, meat, fish and shrimp. The amount of each meal should be smaller than usual and can be gradually increased as the intestinal function recovers. Within 1 month after surgery: limit the consumption of high-protein and high-fat foods, and choose protein-based foods that are easier to digest, such as freshwater fish. Eggs can be made into soup, avoid boiled or fried eggs. Within 3 months after surgery: Adjust gradually according to your condition. However, overeating is not allowed. It should be noted that some gallbladders have lost their function before removal and the bile ducts have been dilated to replace their function, in this case there is no need to control the diet after surgery.
