Generally speaking, due to pathological moderate damage, patients in Renal insufficiency compensatory period and during the course of azotemia, who have high level of serum creatinine and start to have sorts of mild clinical symptoms, should control the intake of salt. If hypertension and edema appear, such patients should be given low salt or salt-free diet, respectively.
patients should control the intake of protein in this period because of nitrogen qualitative hematic disease and renal insufficiency.
In order to control the worsening of renal function, they should select the diet which are rich in high-quality protein.
Vitamin D consumption
It is suitable for patients who have kidney failure and high creatinine to choose to eat food which are rich in vitamin A, vitamin B2 and vitamin C .Renal insufficiency patients who have high creatine levels but without oliguria and edema should be allowed to eat salt and drink water. For patients who have severe edema, hypertension and even heart failure, salt should be strictly restricted.
Besides diet, patients with high creatinine should also pay attention to the restriction of cigarette and alcohol. Cigarette and alcohol mainly damage kidneys and blood vessels, so, if patients have much more cigarettes and too much alcohol, there will be greater damage to their blood vessels in the kidney. If so, patients will get increased renal artery sclerosis and promoted glomerular sclerosis.
