The kidney works 24 hours a day like the heart, but people tend to pay less attention to it compared with the heart because of its stronger reserve capacity. When it is mildly damaged, the patient has no obvious clinical symptoms and the condition is neglected, but when the kidney is seriously damaged, its reserve capacity gradually decreases and the consequences are serious. According to the preliminary survey of the International Society of Nephrology, the prevalence of chronic kidney disease in people over 40 years of age is 8% to 9%. Compared with other major diseases that endanger human health, it is more insidious, with no obvious symptoms at the onset, and many patients have developed uremia when they seek medical attention. The average annual medical cost of uremic patients is more than 100,000 yuan, and the high cost of treatment brings an unbearable burden to society and families. Many families are thus “impoverished and impoverished because of the disease”. Therefore, we should cry out to those people who do not pay attention to their kidneys: “Please protect your kidneys”. Measures to protect the kidneys are roughly as follows: 1. Timely detection and treatment of those diseases that induce kidney damage: (1) Early diagnosis and treatment of cold, pharyngitis, tonsillitis and other diseases. If the eyelids or facial swelling is found 1~3 weeks after these diseases, urine test should be done immediately and the changes should be tracked. (2) Allergic diseases such as urticaria, allergic purpura, etc. should be tracked for changes in urine. (3) With infectious skin diseases such as boils and pustular sores, the urine should be observed for any changes. (2) Pay attention to the damage to the kidneys from systemic diseases: If you have hypertension, diabetes, connective tissue diseases, etc., you should have regular urine tests to detect kidney damage early and treat it early to avoid progressing to serious kidney damage. 3, pay attention to the regularity and rationality of the diet, do not overeat, as age increases must also moderate the diet, do not be too full. 4, pay attention to the careful use of drugs, especially in the use of antibiotics, should follow medical advice, especially patients who have been diagnosed with kidney disease, try to avoid the use of drugs that may damage the kidneys. 5, pay attention to exercise, choose a suitable exercise to adhere to exercise, in order to enhance physical fitness, improve the ability to resist disease.
