March 10 is world kidney disease day. At present, 850 million people in the world suffer from kidney disease. In China, the prevalence of chronic kidney disease has reached 10.8%. In recent years, the prevalence of chronic kidney disease has increased year by year, and its disability and mortality rate ranks first among all diseases. Li Rong, chief physician of Nephrology Department of the second hospital of Medical University, suggested that the onset of chronic kidney disease is hidden and irreversible, which should be paid attention to. The important role of kidney Kidney is one of the most important organs except the heart and brain, but the health of kidney is often ignored, and the awareness rate of kidney disease is also very low. The kidney is the "purification factory" of the human body. With its small volume and weight, it bears a lot of workload. Most of the waste in our body is processed by the liver and kidney. The body discharges metabolic waste and acidic waste by the kidney. Another function of the kidney is endocrine. Insufficient erythropoietin can cause renal anemia. At the same time, the endocrine hormones in the kidney will also affect people's blood pressure. The worse the renal function, the harder it is to control the blood pressure. Irreversible chronic kidney disease The etiology of chronic kidney disease is diverse and complex. At present, the top three causes of chronic kidney disease are glomerulonephritis, diabetic nephropathy, and hypertensive kidney injury. According to statistics, before and after 2011, chronic uremic patients in China mainly came from patients with hypertension and diabetes. Young people are mainly patients with high uric acid. These high-risk groups should pay special attention to kidney health every day. Chronic kidney disease is irreversible, and the early symptoms are not typical and obvious, but some signs can be used to prevent or delay the occurrence of renal failure. At ordinary times, we should pay attention to the color of urine and the foam of urine. In some early stage of kidney disease, the color of urine is deepened, and the phenomenon of froth appears, which indicates proteinuria. Proteinuria refers to the presence of excess protein in the urine, mostly from kidney disease. It is suggested that you get into a habit of checking your urine every morning after urinating, and sometimes it will bubble faster due to the flow rate of urine, but usually it will disappear in half a minute, while the proteinuria lasts for several minutes without disappearing. Especially after a cold and streptococcal infection, after anti-inflammatory treatment, it is easy to develop chronic glomerulonephritis. We should also pay attention to the observation of urine status at ordinary times. Of course, it is not urine foam that proves to suffer from kidney disease. There are some uncertain symptoms. It is recommended to do standard urine examination in hospitals. Everyday, young people should pay more attention to urine color, foam and inflammation after cold. The elderly should pay attention to hypertension and diabetes, which will affect the progress of renal function. In addition, some people may have backache and fatigue; Nausea and vomiting; High blood pressure and difficult to control; Hematuria; Unexplained edema of eyelids, face, lower limbs and even the whole body; Anemia, etc. In addition, patients who have undergone coronary angiography should also pay attention to kidney health at any time. When there are some uncertain symptoms, we should immediately standardize medical treatment, do not take drugs and supplements indiscriminately, and do not trust folk prescriptions, so as not to cause greater damage to the kidney. Prevent kidney disease by doing so In terms of diet, we should pay attention to low purine, low salt and low-fat diet. People with poor renal function should pay attention to low protein diet. Daily drinking water should be regular. Don't drink water only when you are thirsty. Normal people drink 1000 ml to 2000 ml per day. In addition, exercise should be carried out to control body weight. Patients with hypertension should control blood pressure to meet the standard, and diabetics should control blood sugar level, and do not abuse drugs and health products. (outlook new era)
