Acute cholecystitis and biliary colic are mostly acute suppurative inflammation of the gallbladder, often caused by stones becoming lodged in the neck of the gallbladder or in the cystic duct, preventing the concentrated bile from being discharged and leading to gallbladder distension. The concentrated bile exerts a strong chemical stimulus on the gallbladder wall, which can easily lead to a secondary bacterial infection. Due to bacterial invasion, the gallbladder wall becomes edematous and inflamed, which in turn can cause impaired blood supply to the gallbladder wall, thereby further exacerbating or worsening the gallbladder inflammation. Overeating, consuming excessive greasy food, and fatigue can all trigger acute attacks of cholecystitis and biliary colic. Therefore, to inhibit gallbladder contraction, food should be withheld during the acute phase of cholecystitis and cholelithiasis, with various nutrients supplied intravenously. Once the acute phase has passed, when oral feeding is resumed, pure carbohydrate liquid diets should be consumed, such as rice soup, fruit juice, jelly, arrowroot starch, and almond tea. Fatty and irritating foods should be avoided. After the condition improves, a low-fat semi-liquid diet or low-fat soft food may be given, with small, frequent meals, while continuing to limit fat intake.
