As a common kidney disease, renal atrophy is gradually threatening our health, and early detection of this disease can effectively slow down the development of the disease. Experts pointed out that early prevention of renal atrophy is very helpful to avoid this disease to bring more harm to the body, here we understand the early prevention of renal atrophy. Early prevention includes the following aspects: (1) active treatment of primary disease: various acute and chronic glomerulonephritis, lupus nephritis, purpuric nephritis or diseases that may involve the kidneys (such as hypertension, diabetes mellitus) active treatment, to prevent the occurrence of chronic renal failure. (2) Application of angiotensin-converting enzyme inhibitors: not only can control systemic hypertension, but also can correct the glomerular hyperperfusion, high filtration state, there is a delay in the occurrence of renal failure. Commonly used clinical drugs are captopril, lodinexin and lisprostadil. (3) Reasonable dietary regimen: The protective effect of low protein, low phosphorus and low fat diet on renal function in chronic kidney disease has been confirmed by laboratory and clinical. It is now emphasized that in order to prevent the occurrence of chronic renal failure, protein intake should be restricted when the blood muscle intoxication is 159.1 micromol/liter. (4) Avoid or eliminate certain risk factors: The application of drugs toxic to the kidneys, serious infections, dehydration, urinary tract obstruction (e.g., stones, prostatic hypertrophy), trauma and other factors can often aggravate the original renal disease, deteriorate renal function, and contribute to the occurrence of renal failure. In fact, regular, high-quality follow-up can reduce or avoid the occurrence of these risk factors, or early detection and correction. The above is the preventive measures for renal atrophy disease, I hope to understand the above, we can love life seriously attention, while patients do a good job in the process of daily effective prevention, patients and friends should also be active treatment, pay attention to the diet of the reasonable collocation and health care in daily life, so that the condition will be better.
