Another causative cause of kidney failure disease is actually diabetic nephropathy, a longer course of diabetes. About half of the diabetic patients who develop kidney disease develop renal failure after 5 years, and other complications occurring in diabetic patients, such as the reticuloendothelial system, the vascular system, and neurological complications may also occur at the same time. Severe hypertension is also a cause of renal failure. Severe hypertensive disorders may cause atherosclerosis of small renal arteries, reduction of renal blood flow, and impairment of renal function, etc. In addition, lower urinary tract obstruction may occur. In addition, lower urinary tract obstruction is also one of the causes of renal failure. In addition, patients with poor drainage of the lower urinary tract, such as benign hypertrophy of the prostate gland, causing the patient’s urine reflux, causing the patient to produce hydronephrosis, compression of the patient’s normal renal tissues, thus causing the patient to develop renal failure. Some other reasons may also be one of the causes of kidney failure. For example, patients often use some nephrotoxic drugs for a long period of time or some other common diseases caused by more serious kidney damage, resulting in patients with chronic renal failure. For renal failure, patients with renal failure can supplement some adequate proteins and so on, which is very helpful to slow down the condition of renal failure. The basic principle of diet for kidney failure patients is generally a high quality low protein diet. About 50% to 60% of the diet should be high quality proteins containing essential amino acids, such as eggs, milk, fish, lean meat and other animal proteins. Patients with renal failure should try to eat less food rich in vegetable protein, such as peanuts, beans and other products, because most of these substances contain more non-essential amino acids, which cannot meet the needs of patients with renal failure.
