The main function of the gallbladder is to store bile. After eating, the gallbladder contracts, allowing the stored bile to drain into the duodenum to help digest and absorb food. So, once the gallbladder is removed due to gallbladder pathology, will it affect the digestive function and health of the body? In fact, although this concern is somewhat justified, it is not entirely correct, because the gallbladder is not an indispensable organ in the body. Many higher animals, such as horses, deer, elephants and whales, are born without gallbladders, and their lives are not very different from those of some animals with gallbladders. There are a few people who are born without a gallbladder due to abnormal embryonic development of the gallbladder, but they continue to live the same life as normal people. After cholecystectomy, the patient’s original symptoms disappear immediately. Although the gallbladder loses its function of concentrating and storing bile, there is no major impact on the patient’s digestive and absorption functions. Scientific experimental studies have shown that the digestive and absorption functions of patients after cholecystectomy do not differ much from those of normal people. In patients with cholesterol stones, after removal of the gallbladder, the content of bile acids in the bile will slowly increase so that the supersaturated bile before surgery can gradually become normal bile. Therefore, cholesterol stones will not recur as long as the bile duct stones have been completely removed at the time of gallbladder removal. Therefore, there is no need to worry about the adverse effects on health and digestion and absorption after gallbladder removal. Furthermore, after gallbladder removal, the wall of bile duct will be thickened and the mucus glands of bile duct will be increased. If the body consumes too little fat, it will not be beneficial to the body, but rather detrimental to human health. Of course, the recovery of the body after surgery and the establishment of compensatory functions should be a process, the intake of animal fat and eggs should not be too much, and the fat content in food should be gradually increased, so that the body has a gradual adaptation process.
