Chronic renal failure is not just a disease, but a phenomenon. Many people think that chronic renal failure is caused by acute renal failure, in fact, things are not so simple, suffering from chronic renal failure will cause great harm to human health, so we must do a good job of prevention of the disease in life, in order to prevent themselves from being harmed as well. So, what are the early prevention methods of chronic renal failure? 1, avoid the application of drugs that are toxic to the kidneys. Drugs are of course used to cure the disease, but drugs not only have the role of curing the disease, there will be adverse reactions that can lead to the disease. These adverse reactions can be very light, such as some gastrointestinal symptoms, such as bloating, nausea, etc., but they can also be very serious, such as acute renal failure, acute liver damage, acute aplastic anemia and so on, and the patient’s life is even in danger. 2.Actively treat the primary disease. The key to prevent chronic renal failure is to control the primary disease well. The most common primary disease is chronic glomerulonephritis, which accounts for about 50%~60% of all morbidity factors, and there are also chronic pyelonephritis, lupus nephritis, urinary stones, diabetic nephropathy, hypertension, renal artery stenosis, drug toxicity nephropathy and so on. These diseases that may cause chronic renal failure should be emphasized and actively treated. 3.Reasonable diet program. In order to prevent the occurrence of chronic renal failure, patients with blood creatinine at 159.1 micromol/liter should limit protein intake. In recent years, with the improvement of living standard, high protein diets such as big fish and meat are put on people’s table, plus the pressure of life, bad habits caused by work, etc., which unknowingly bring a heavier burden to the kidneys. Therefore, it is necessary to adhere to a reasonable diet for the prevention of renal failure. 4.Control blood pressure. The control of renal or primary hypertension can stop the progress of glomerulosclerosis. The former is mainly to control glomerular hyperperfusion, and the latter is mainly by applying antihypertensive drugs. Control of hypertension (or diabetic nephropathy) can be applied to small doses of angiotensin-converting enzyme inhibitors (mercaptopropionic acid), which can reduce the intraglomerular pressure, correct the glomerular hyperperfusion, high filtration state, and have the effect of delaying the onset of renal failure, and is suitable for application in the early stage of renal failure (blood creatinine <442 micromol/liter). Early prevention of chronic renal failure is a very critical step, so I hope you can pay attention to it in your life, never have any ambiguity, otherwise you will join the ranks of chronic renal failure patients. As for how to prevent, the above also introduces you to four effective prevention methods, I hope you take it seriously.
