Kidney injury “trap”
With the increase of age, various organs of our body will age. The performance of kidney aging is that the size of the kidney may shrink and the kidney function will decline. Experts tell us that after the age of 40, the kidney function will decline by 1% every year. The ability of the kidneys to detoxify also decreases, greatly increasing the risk of death. There are many potential kidney-injuring factors in daily life, and these kidney-injuring factors are more likely to damage the kidneys of the elderly, so how can the elderly avoid the kidney-injuring “trap” in life?
Chronic kidney disease is a common disease. The prevalence rate in my country is 10.8%. One in 10 people may have chronic kidney disease, which is close to the prevalence of diabetes.
Chronic kidney disease not only can lead to end-stage renal disease due to its own disease progression, but also leads to high morbidity and mortality of cardiovascular and cerebrovascular diseases. In addition, the incidence of anemia, fractures, urinary tract infection, pneumonia, sepsis and other infections in patients with chronic kidney disease can be increased several times or even more than 10 times.
In addition to chronic glomerulonephritis, diabetes, hypertension and other major kidney damage factors, some frequently used items are hidden kidney damage factors in the elderly.
Kidney injury behavior 1
Inappropriate use of diuretics and metformin
Diuretics and metformin are two drugs that patients with high blood pressure and diabetes often take, but improper use may also damage the kidneys.
In malignant hypertension, be careful of kidney damage with diuretics. The blood pressure of malignant hypertension is often 200/130mmHg. The high blood pressure causes the kidneys to diuretic desperately to lower the blood pressure, and the body is in a state of water shortage. In addition, taking diuretics to lose weight can cause systemic dehydration and kidney failure.
Metformin is a first-line drug for the treatment of diabetes. It has no direct damage to the kidneys, but if it is a person with severe kidney disease (stage 4 or 5 kidney disease, dialysis patients), the excretion of metformin will be hindered, resulting in lactic acid. Acidosis, aggravating kidney damage.

When I found Director Zhou, his creatinine had risen to 1100, and his mouth even smelled of urine, which belonged to severe renal failure. He was diagnosed with membranous nephropathy and acute interstitial nephritis caused by drugs. Fortunately, after taking medication, Mr. Wang was freed from Dialysis has maintained a stable state for more than ten years to the present. When recalling his past experiences, Mr. Wang felt that his severe kidney disease might be related to taking antipyretics and drinking at one time.
