In the clinic many patients have recurrent gallbladder stones, stomach pain, bloating, sometimes so much pain and fever that they have to go to the hospital for injections. Patients are told that they should have surgery to remove the gallbladder so that the lesion can be completely removed. But many people have the opinion that the gallbladder cannot be removed. If you ask him why, he will answer: if the gallbladder is removed, people will have no guts, their guts will be too small to do anything; or if the gallbladder is gone, people will have no bile, so how else can they digest food. So these people have a sense of fear about gallbladder removal surgery. Here we will talk to you about the function of the gallbladder. First of all, the gallbladder has nothing to do with bile, although both have the word “bile”, but there is really no connection. In popular fiction, it is said that if someone has a lot of guts, he also has a lot of guts, which is just a legend without any scientific basis. Because the current medical science has confirmed that the function of the gallbladder is related to the digestion of food, while the human guts is related to the psychological quality. Secondly, the gallbladder does not produce bile, bile is produced by the liver and bile ducts, which is mainly produced by the liver, a normal person can produce about 800 to 1200 ml of bile every day, 75% of which is produced by the liver, the rest is produced by the bile ducts. The main function of the gallbladder is to store bile. After the liver produces bile, it gradually converges to the common bile duct through the tiny bile ducts in the liver, just as many small streams eventually merge into a large river. The bile finally flows through the common bile duct to the duodenum to help the body digest food. The gallbladder is a small bag connected to the common bile duct and is closely connected to the liver. Its functions are: (1) Storage of concentrated bile: A normal gallbladder can store about 50 ml of bile, and the mucous membrane of gallbladder has a strong absorption capacity, which can absorb 90% of the water in the bile, so about 500 ml of bile enters the gallbladder every day. With the concentration of bile, bile salts, bile pigments and cholesterol in bile are concentrated, and the concentration is 10 times that of bile in the bile duct. (2) Discharge of bile: Bile is continuously produced by the liver, but the body needs a lot of bile only when it eats. So when you don’t eat, bile can be stored in the gallbladder, and when you eat, the gallbladder contracts and a large amount of bile enters the intestine through the bile ducts to help digestion. But the bile will not be completely excreted, usually 15% of the bile will remain in the gallbladder. (3) Secretion function: In addition to absorbing water from bile, the mucous membrane of gallbladder will also secrete some fluid, about 200ml per day. It mainly protects the mucous membrane of gallbladder. From the above description, it can be seen that the bile production and food digestion of human body will not be affected after gallbladder removal. After removal of the gallbladder, the common bile duct may be thickened and the wall of the duct may be thickened, thus causing a certain concentration of bile when passing through the duct. Cholecystectomy has been performed for more than 100 years now, and so far, scientists at home and abroad have not found any effect on human health after gallbladder removal. Therefore, for gallbladder disease, if the doctor thinks that the gallbladder should be removed, the patient should not have any fear because the gallbladder that is removed is a diseased, poorly functioning or even non-functional gallbladder, which will not only play a normal physiological role in the body but will only create problems for the body.
