1 asymptomatic proteinuria or hematuria , urinary protein loss of more than (1 ~ 2g · d-1). Available to the general diet, a little salt restriction . But as more urinary protein loss , or low plasma protein , without azotemia , may be appropriate to increase the dietary protein quality, according to the daily 1g · kg-1 to normal supply requirements , the need to consider the increased urinary lost in the protein , according to a recent opinion , the long-term high protein load will increase the burden on the kidneys , resulting accelerated deterioration of renal function .
2 acute exacerbation of chronic glomerulonephritis , according to the principles of diet therapy of acute nephritis , nephrotic syndrome, there is a reference to that section by dietary treatment .
3 patients with hypertension, chronic nephritis with moderate degrees of renal function most damage for the control of blood pressure , salt intake should be limited , given salt diet seriously, given the short salt-free diet , not only due to multi sodium intake can increase blood pressure, and can aggravate kidney damage , so even if the blood pressure returned to normal, it is appropriate in light of food in order to avoid further deterioration of renal function , protein quality control should be matched appropriately .
4 renal dysfunction should be appropriate to limit intake of protein, total daily intake (including staple foods containing protein ) <30 ~ 40g, use more milk, egg quality , high biological value protein , and the appropriate swap fish , meat, chicken and other animal protein to increase appetite. When the patient was significantly impaired renal function , do not excessively restrict sodium, avoid hypovolemia aggravate renal dysfunction and even appear azotemia .
