”Kidneys are the source of life, and protecting them is protecting life.” Experts remind that patients with chronic kidney disease should be given timely and effective treatment to delay or reverse the progress of chronic kidney disease as much as possible, with a view to protecting damaged kidneys from chronic kidney failure as much as possible. I. Pay high attention to the “distress signal” issued by the kidneys For patients with chronic kidney disease, such as the sudden occurrence of severe edema, abnormal urine (short-term significant reduction in urine volume or a sudden increase in nocturia, urine discoloration, urine with a large amount of foam, etc.), anorexia or even nausea and vomiting, skin itching difficult to relieve, etc., we should pay sufficient attention to whether the disease In a short period of time there is a significant progress, this time need to seek medical attention as soon as possible. II. Protect the kidney and actively treat the primary disease Those with diabetes, hypertension and hyperlipidemia should actively treat the primary disease to control blood sugar, blood pressure and lipids within the standard range. A hyperglycemic environment tends to aggravate renal vasculopathy, so it is especially critical for diabetic nephropathy patients to maintain stable blood glucose to protect the kidneys. A high blood pressure environment can aggravate the kidney burden, so you can imagine how important it is to maintain stable blood pressure to protect the kidneys! III. Protect your kidneys by sticking to a high-quality, low-protein diet A high-quality, low-protein diet has the ability to protect kidney function and reduce proteinuria. Low protein, that is, less protein intake than the average person. If the kidney disease patients with normal blood creatinine, the daily protein intake is 0.8 g/kg of body weight; for those with more serious kidney function impairment, the daily protein intake should be more strictly limited, generally not more than 0.6 g/kg of body weight. Quality protein, i.e., this protein intake should come from animal proteins such as milk, eggs, lean meat, etc., rather than vegetable proteins. These two items are the basis of dietary therapy and are collectively referred to clinically as a high-quality low-protein diet. Long-term adherence to a high-quality, low-protein diet is instrumental in protecting the kidneys and delaying progression to chronic renal failure. IV. Protect the kidney, avoid or timely correct risk factors that aggravate kidney damage Clinically, we may encounter some patients who have chronic kidney disease control for many years without aggravation, but due to a serious kidney damage leads to rapid development of chronic kidney failure. So how to avoid and correct these factors in time? High purine diet can increase the production of uric acid, the formation of uric acid crystals blocking the renal tubules damage to the kidneys, should be avoided as far as possible. These foods include: animal offal, seafood, fish eggs, fish skin, beer, soybeans, purple cabbage, shiitake mushrooms, spinach, etc. In case of various infections, such as cold, skin infections and other inflammatory diseases, you should treat them in time and not carry them hard. The more proteinuria, the more damage to the kidney, you should actively cooperate with the doctor to control the level of proteinuria. Also correct anemia, correct water electrolyte and acidosis, stay away from nephrotoxic drugs or other physical and chemical factors that cause kidney damage, etc. V. Protect the kidney, adhere to treatment and follow-up Chronic kidney disease as a chronic disease, for each patient, is to be prepared for long-term treatment. Regular review and follow-up at regular intervals and careful compliance with medical advice are the keys to protect the kidney and prevent the occurrence of chronic renal failure.
