Chronic renal failure (CRF) refers to the progressive renal parenchymal damage caused by primary or secondary chronic kidney disease from various causes, resulting in a serious clinical syndrome of renal decompensation, retention of metabolites, imbalance of water, electrolyte and acid-base balance, and systemic involvement. The disease progresses slowly, or even the kidney function is progressively reduced or deteriorated until uremia occurs. Although dialysis and renal transplantation can improve the survival rate of some end-stage patients, they are not suitable for early and mid-stage treatment, and medical costs are expensive. Therefore, how to delay or stop the pathological process of chronic renal failure in early and mid-stage patients with CRF is a hot and difficult point in modern kidney disease research. Traditional Chinese medicine has a unique understanding and treatment of this disease, which occupies an important position in the non-dialysis therapy of chronic renal failure, especially for the stage of CRF compensated to pre-uremic, Chinese medicine treatment has obvious advantages. What are the precautions for chronic renal failure daily life? 1, pay attention to prevent throat, lung, urinary tract infections, so as not to aggravate the infection of chronic renal failure. 2, avoid cold, exertion, diarrhea, trauma, etc.. Because every infection may aggravate the disease. 3, the infection should be timely use of antimicrobial control of infection, strictly prohibited the use of gentamicin, kanamycin, amphotericin, avoid toxic drugs for the kidneys, otherwise it will aggravate and accelerate the deterioration of kidney function. 4, control hypertension, because hypertension can lead to faster deterioration of kidney function, the general blood pressure is maintained at 130/80mmHg or less is appropriate. 5.The primary disease should be actively treated to reduce the loss of protein. Because hypertension and proteinuria are independent risk factors for the progression of chronic kidney disease, and proteinuria is the strongest damage factor, long-term large amount of proteinuria can contribute to the deterioration of kidney function. 6, diet regimen. Dietary regimen is the most basic and effective measure of non-dialysis therapy for chronic kidney failure, and is the basis of all drug therapy. Its role is as follows: (1) maintain good nutritional status; (2) delay the progress of renal failure; (3) prevent and reduce the metabolic disorders caused by renal failure; (4) delay the time to enter dialysis and reduce the number of dialysis after entering dialysis. The content includes: high quality and low amount of protein diet; high calorie diet and moderate vitamin and mineral intake; control of sodium, potassium, phosphorus, purine and lipid intake.
