After kidney transplantation, patients should eat more light food, more vitamin-rich food and high protein diet, and less cholesterol-rich food. After kidney transplantation surgery, when the intestinal function is basically restored, the patient will start to defecate, and gradually change from liquid diet to general diet. After normal diet is restored, the patient can eat more high-protein food, such as pigeon, pig’s trotters and so on. Eat more vitamin-rich foods, such as carrots and tomatoes, to improve resistance and promote recovery. Meanwhile, you should avoid greasy, spicy and other stimulating foods, and try not to eat high cholesterol foods, such as animal offal, seafood and other foods, which will increase the burden on the kidneys and will affect the recovery of the disease. Meanwhile, you should quit smoking and drinking, and pay attention to rest. All foods should be eaten in moderation, not too much, and reasonably matched in order to achieve the highest nutritional value of food.
