After cholecystectomy, bile secreted by the liver is directly discharged into the intestine, which may lead to fat indigestion, affect the absorption of fat-soluble vitamins, and cause seborrhea, which usually recovers in 2-3 months. Therefore, the intake of fat should be limited in the early stage after cholecystectomy, and the method of eating less and eating more meals should be adopted, and each meal should not be too full. According to the tolerance to food, the intake of fatty foods should be gradually increased.
