“Either excessive intake or over restriction of water is harmful. Salt intake selleck compound is preferably restricted to less than 6 g/day. Obesity is recommended to be controlled with BMI being less than 25 kg/m 2 . Smoking
cessation is essential for suppression of CKD progression as well as CVD development. Restriction of protein intake to 0.6–0.8 g/kg/day exerts favorable effects in CKD stages 3–5. It is better for calorie intake to be 30–35 kcal/kg/day, although 25 kcal/kg/day can be applied 4SC-202 nmr in obese diabetics. Proper consumption of alcohol as ethanol is less than 20–30 mL/day in men (corresponding to 180 ml Japanese sake ), and less than 10–20 mL/day in women. Note: “kg body weight” indicates “kg” in the standard body weight, but not in the Montelukast Sodium current real body weight. standard body weight (kg) = [height (m)] 2 × 22 The diet therapy Morbid states requiring diet therapy and its contents are summarized in Table 17-1. The nephrologists participate
in determination of diet therapy for CKD in stages 3–5. Table 17-1 Pathophysiology of kidney disease and diet regimen Pathophysiology Diet therapy Effect Hyperfiltration Salt restriction (<6 g/day) Protein restriction (0.6–0.8 g/kg/day) Decrease in proteinuria, retard GFR decline ECFV excess Salt restriction (<6 g/day) Decrease in edema Hypertension Salt restriction (<6 g/day) Lower blood pressure, retard GFR decline Azotemia Protein restriction (0.6–0.8 g/kg/day) Lower BUN, ameliorate uremic symptoms Hyperkalemia Potassium restriction (<1,500 mg/day) Lower serum potassium Hyperphosphatemia Protein restriction (0.6–0.8 g/kg/day) Phosphate restriction (mg) (protein, g × 15) Lower serum phosphate, retard vascular calcification Metabolic acidosis Protein restriction (0.6–0.8 g/kg/day) Ameliorate metabolic acidosis Standard weight (kg) = [Height (m)]2 × 22 ECFV extracellular fluid volume Water Generally water restriction is not required, but in advanced CKD stage, water restriction might be instituted. Salt CKD patients are vulnerable to hypertension.
