Patients with gallstones are perfectly able to eat fungus. As the most common benign disease of the hepatobiliary system, gallstones are caused by an imbalance in the dissolution of cholesterol and bile acids, resulting in the formation of cholesterol crystals that interact with nucleation factors, which in turn form dense stones. Repeated movement of gallstones in the gallbladder can wear away the gallbladder mucosa, which can lead to acute inflammation and manifest as chronic cholecystitis. If secondary bacterial infection develops, it can cause an infectious disease, also known as acute cholecystitis. In patients with gallstones, since the main function of the gallbladder is to store and concentrate bile, the bile is discharged into the intestinal cavity through the contraction of the gallbladder after eating and participates in the digestion of fats in food. Therefore, patients with gallstones are encouraged to eat foods with high protein and low fat, and avoid eating foods that are too greasy.
