Hemodialysis can increase the loss of nutrients, so the dietary management of dialysis patients is different from that of non-dialysis patients, and should be supplemented according to the following requirements: 1. Protein requirement: because hemodialysis treatment often involves the loss of amino acids and a small amount of protein, the dietary principles should be appropriately relaxed, and the daily protein intake can be raised to 1.0-1.2 g/kg body weight. This nutritional standard is reasonable for the maintenance of stable state of hemodialysis patients, but for the relief of pre-dialysis malnutrition and post-dialysis infections, heart disease, gastrointestinal disorders and other conditions is not enough, but also need to supplement additional amino acids and other nutrients. 2.Calorie requirements: adequate calorie intake, the body can effectively utilize the intake of protein and maintain adequate nutrient reserves. Stable hemodialysis patients usually have a total daily calorie intake of about 138-146 kilojoules/kg of body weight when sitting. 3. Limit cholesterol intake: hemodialysis patients are often associated with hyperlipidemia. But limiting cholesterol should be optional, because many cholesterol-containing foods are also the main foods containing high-quality protein, such as meat, eggs and so on. Patients can choose egg white, not only to ensure the intake of high-quality protein, but also to reduce the intake of cholesterol, eating fish or poultry white meat is better than red meat. 4, dialysis patients due to insufficient food, metabolic changes and vitamins lost through dialysis, if not timely supplementation, will lead to vitamin deficiency, such as vitamin C, folic acid, vitamin B1, vitamin B6, vitamin A and so on.
