Due to the presence of anemia, the digestive system of leukemia patients will have a reduced function, and there will be significant nausea, vomiting and other gastrointestinal symptoms when doing chemotherapy, and the appetite will be significantly reduced. Therefore, leukemia patients should eat high-calorie, easy-to-digest liquid food, such as rice, porridge, noodles, vegetable soup and so on. At the same time, you can also eat appropriate high-quality protein, such as fresh fish, soybean products and so on. Due to the reduced digestive function of leukemia patients, it is best not to eat greasy and spicy foods, such as beef, barbecue, etc. In addition, leukemia patients generally have thrombocytopenia, so it is best not to eat too hard foods, such as lamb chops, etc., to prevent these foods from stabbing the digestive tract and causing serious bleeding. Special emphasis is placed on the fact that leukemia patients do not need to take large supplements, and it is not recommended to eat reishi, bird’s nest, etc.
