1.How does biliary colic arise? Does the pain disappear without treatment? Stones are blocked in the gallbladder duct or bile duct, making it impossible for bile to pass through. The body will naturally produce a series of reactions to overcome it, such as gallbladder spasm or contraction of the lower sphincter of the common bile duct, which will produce severe pain if the stones cannot be expelled with great effort. If the pain disappears as a result of the total discharge of the stone, then no treatment is needed, but this rarely happens. The majority of cases are due to the stone temporarily leaving the site of blockage, and under certain conditions, such as eating greasy food, fatigue, drinking alcohol, etc., it can come back again. Therefore, as long as the stone exists, it should be removed firmly. 2.Why do gallstones cause yellow eyes, chills and fever? Bile is produced by the liver and enters the intestine through the bile duct. The bile duct is like a tree, the intrahepatic bile duct is like a branch and the common bile duct is like a trunk. If there is an obstruction in the trunk, the bile produced by the liver cannot be discharged and flows backwards into the bloodstream, where the bilirubin in the bile settles in the eyes and skin, manifesting itself as yellow sclera and skin staining, which is called jaundice. With stones in the bile duct causing poor bile flow, intestinal bacteria will easily enter and multiply, producing toxins, and the body will react with chills and fever. 3.Is it necessary to treat gallstones? Strictly speaking, as long as there are stones, they should be treated, because there should not be stones in the normal biliary system. Some gallstones are inevitably causing different degrees of harm to the human body, some of which are in the early stages and have no obvious manifestations, while others have developed to the point where they must be treated.
