In these high-risk groups, we recommend frequent medical checkups, which can be done once a year to detect the presence of chronic kidney disease early. In addition, the use of a variety of drugs to be particularly cautious, do some preventive work, is able to avoid the emergence of chronic kidney disease early. What kind of methods can be used to detect kidney disease during physical examination? In fact, it is very simple to check a urine routine, which was not checked in the medical examination, but now it is added to the check. At the same time, a blood test to check the kidney function can also detect many patients. At the same time, you can do an ultrasound examination of the kidneys, which is often referred to as ultrasound, through these three tests, the majority of chronic kidney disease can be detected. Although chronic kidney disease does not have specific symptoms, there are some symptoms that can suggest that we may have chronic kidney disease, such as a change in urine volume, especially the amount of urine at night, this should be alert, edema is a very common manifestation of kidney disease, of course, edema has many other manifestations, edema patients we should be alert to whether there is chronic kidney disease. Some people show hypertension, we need to be careful. There are also some bubbles in the urine, or work feel not much fatigue now feel especially fatigue, very easy fatigue, energy and lack of concentration, such some performance are prompted to look at the possibility of kidney disease.
