Gallstones are the most common benign disease of the hepatobiliary system, caused by the imbalance between bile acids and cholesterol dissolution. The most effective and reliable clinical treatment for gallbladder stones is laparoscopic removal of the gallbladder to obtain a cure. Generally speaking, the quality of life of most patients will not be affected after surgery. Patients with gallstones have an imbalance between bile acid and cholesterol dissolution, so the diet usually advocates high-protein, low-fat and vitamin-rich foods, and fish, as high-protein, low-fat food, can be eaten by gallstone patients after surgery. Therefore, patients after gallstone surgery can eat fish.
