Familiarity with the symptoms that may appear in the early stage of chronic kidney disease can serve as a warning for the occurrence of chronic kidney disease, facilitating the early diagnosis and treatment of chronic kidney disease patients and effectively curbing the deterioration of the disease. Usually, when there is a large amount of foam in the urine as well as blood color in the urine or an increase in nocturia, i.e. urine protein and red blood cells in the urine in routine urine examination, it may be an early warning sign of the early occurrence of chronic kidney disease. The symptoms of early chronic kidney disease are not obvious, such as the general patients with chronic nephritis do not have particularly obvious symptoms of discomfort. Therefore, when there is abnormal urine, it is recommended to seek medical examination and diagnosis. Once patients feel that they have obvious fatigue, anemia and other very obvious symptoms to go to the doctor, the chronic kidney disease may have passed the early stage, which will bring greater difficulty for the late treatment of chronic kidney disease. Chronic kidney disease is characterized by “three highs” and “three lows”: high incidence, high prevalence of associated cardiovascular disease and high death rate; low awareness of chronic kidney disease in society, low prevention and treatment rate, and low awareness of associated cardiovascular disease. The survey shows that the prevalence of chronic kidney disease in people over 40 years old in China is more than 10%, but the awareness rate is less than 5%. In China, the largest number of patients with chronic kidney disease occurs in glomerulonephritis, accounting for 40%. Other secondary chronic kidney diseases are increasing with the change of dietary structure and living habits of our population. How to prevent chronic kidney disease? 1, to avoid overwork, mental stress Overwork, night driving, exams and school stress, etc., can make the chronic nephritis condition aggravated. You should have good habits and maintain a regular life. You should arrange your daily routine, participate in the right amount of activities and strengthen your physical exercise, but avoid overworking. The body’s resistance should be strengthened through proper nutrition. Pay attention to personal hygiene and environmental hygiene, develop good living hygiene habits, and keep a relaxed and happy mood at all times to strengthen self-care awareness. The most common causes of acute nephritis are bacterial or viral infections, especially upper respiratory tract infections, asymptomatic bacteriuria, influenza, pharyngitis, tracheobronchitis, etc., which may aggravate the symptoms of chronic nephritis. 3, pay attention to diet and nutrition Nephritis patients should avoid high protein diet, pay attention to food safety, eat more fresh fruits and natural foods. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things.
