Chronic renal failure (CRF) lesions are irreversible, incurable, terminally ill people to rely on dialysis or kidney transplantation to sustain life, the early treatment for the patient to control the speed of disease and delay the arrival of dialysis time. Non-dialysis stage of diet therapy are very important to slow down the deterioration of renal function in one of the effective 1. Such as the merger of patients with chronic renal failure have edema and hypertension, should be low-salt (<3g / d) diet, for edema heavier or Urine less, and should be limited to the amount of water and high potassium food (longans, tremella, sesame, etc.) . 2. Chronic renal failure patients before dialysis in the absence should be given to low-protein diet to reduce the metabolic products (blood urea nitrogen) sources, to alleviate the burden on the kidneys, slowing down the pace of deterioration of renal function. Protein intake should be based on the degree of renal injury in a reasonable adjustment. When the glomerular filtration rate (GFR) reduced to 50ml / pm the following should be carried out when appropriate protein restriction (0.6g/kg), to meet the basic needs of the physical body, without malnutrition happen. GFR <10ml / min, that is, a view uremia, protein should be strictly limited to 20g / d, GFR> 20ml / points may add 5g / d. And requested more than 60% for high-quality protein, essential amino acids that contain animal protein, such as eggs, milk, lean meat and so on. In order to prevent malnutrition brought about by low-protein, essential amino acids can be added and mixed α-keto acid preparations, α-acid itself does not contain nitrogen, and ammonia in the body into the corresponding essential amino acids (EAA), EAA at Synthesis protein process, can be used as part of urea, it can reduce the level of blood urea nitrogen to improve the symptoms of uremia. 3. High-calorie intake: adequate intake of carbohydrates, fats supply the body with enough calories to prevent protein for the provision of heat to break down, reducing the consumption of protein. Enough for the intake of calories can be consumed many margarine, vegetable oil and sugar. Food should be rich in vitamin B, C, folic acid, can also be given to oral tablets. 4. Chronic renal failure patients often have high phosphorus, hypocalcemia, easily lead to renal osteodystrophy, should be taken to limit phosphorus diet (per gram of protein containing 15mg of phosphorus, so limit intake of protein also limits the phosphorus taken income) and the use of intestinal phosphate binder. Calcium should be added, should be added every day 1000 ~ 1500mg, such as calcium carbonate, calcium supplements can not only correct the acidosis, it is phosphorus binders. 5. Has been operating for dialysis patients with chronic renal failure, you do not need to strictly limit the diet, but it should be in accordance with the height, weight, mode of dialysis, dialysis frequency and volume to develop programs suited to their diet. 2009-03-11
