Many patients with chronic nephritis find it difficult to say when their disease started, and most of them say they have been very tired for some time now. Therefore, it is very important to pay attention to early prevention and reasonable arrangement of life for people who work intensely and are prone to fatigue, especially those who are engaged in IT, engineering technology, banking, performing arts, etc. They often need to work overtime and stay up late, and are under a lot of pressure, so they should especially pay attention to the combination of work and rest, and avoid cold and infection. If there is a cold and other diseases, it is important to pay attention to the timely rest and treatment. It is also necessary to strengthen nutrition, exercise properly, enhance body resistance, maintain good living habits, and conduct regular body checkups. It is best to test urine protein (including microalbumin) and blood creatinine (to assess kidney function) during physical examinations, which is the most effective and easiest way to detect kidney lesions at an early stage. For people with diabetes, hypertension, obesity, hyperlipidemia, smoking or over 50 years old, it is more important to dynamically observe the changes of the above indicators. It is also recommended that people over 40 years of age should have their kidney function evaluated as a mandatory part of their annual routine physical examination. It should also be included as a compulsory item in the medical examination for school admission, military recruitment and employment recruitment, so as to prevent problems before they occur. Once you have back pain, increased foam in urine that does not subside easily, hematuria, increased nocturia, decreased urine volume, increased urine albumin excretion, swollen eyelids or lower limbs, dizziness and other conditions that may indicate abnormal kidney function, you should pay great attention to it and go to a regular hospital in time to avoid small problems from becoming big ones.
