The diet after endometrial cancer surgery should follow the following principles. Firstly, after endometrial cancer surgery, eating should not be too early, and generally, a small amount of water should be started after anal discharge. If there is no discomfort, you can eat liquid food, such as rice soup, vegetable soup, etc., and then gradually transition to soft food and common food. Secondly, the diet of endometrial cancer should be light, with nutritious and easily digestible food. For old and frail patients, they should eat more liquid and semi-liquid food to facilitate digestion. Such as lotus root powder, orange juice, etc., or lean meat or fresh fish soup can not only ensure nutrition but also enhance appetite and promote patient’s recovery. If the patient’s nutritional status is poor and the general diet cannot meet the nutritional needs, he can take some high-energy comprehensive nutritional quality preparations orally, such as Neng Quan Su, to improve the malnutrition status.
