Chronic renal failure diet

Chronic renal failure diet

◇ CRF patients often have high phosphorus, hypocalcemia, easily lead to renal osteodystrophy, should be taken to limit dietary phosphorus (15mg per gram of protein contains phosphorus, it also limits the intake of protein while limiting the intake of phosphorus) and use of intestinal phosphate binders. It should be added calcium daily should be added 1000 ~ 1500mg, such as calcium carbonate, calcium can either correct the acidosis, it is phosphorus binders.

◇ dialysis CRF patients already, and you do not need a strict dietary restrictions, but it should be in accordance with the height, weight, dialysis, dialysis often develop their own urine and diet program.

◇ CRF patients not on dialysis before, should be given to low-protein diet to reduce the source of metabolites (urea nitrogen), reduce the burden on the kidneys, slowing the rate of deterioration of renal function. Protein intake should be reasonably adjusted according to the degree of renal function impairment. When the glomerular filtration rate (GFR) decreased to 50ml / min or less should be adequate protein restriction (0.6g / kg), to meet the basic needs of the Physiologic, without getting malnutrition. GFR <10ml / min, that is, uremia, protein should be strictly limited to 20g / d, GFR> 20ml / min, can be added 5g / d. And requires more than 60% of high-quality protein, essential amino acids, ie containing animal protein, such as eggs, milk, lean meat and so on. To prevent low protein caused by malnutrition, it can add a mixed preparation with essential amino acids and α- keto acid, α- keto acid itself does not contain nitrogen in the body combine with ammonia to the corresponding essential amino acids (EAA), EAA synthesis protein process, you can use a portion of urea, it can reduce blood urea nitrogen levels, improve the symptoms of uremia.

◇ CRF patients as associated with edema and hypertension, should be low-salt (<3g / d) diet, edema, heavier oliguria, should limit the intake of water and potassium foods (longan, white fungus, sesame, etc.).
