Mr. Ma is a successful person, who is already a very famous entrepreneur in the same industry, and his department is well organized, the quality of service is praised by customers, and the efficiency is increasing day by day. In addition to his university degree, he has a flexible mind and down-to-earth dedication. His career is flourishing, but his body has recently felt some abnormalities, somehow, in recent days, frequent edema, urine volume decreases, nausea and vomiting, work can not hold on. To the hospital, was found to be suffering from chronic nephritis, kidney damage has reached the uremic phase. ”I’ve been sick for less than 20 days, it’s chronic? The kidneys will be destroyed so badly?!” This fact is unbelievable and unacceptable to Mr. Ma, but the test results in front of him are facts. In fact, this is not only Mr. Ma? There are many people who often forget to work, usually “feel good”, but how did not think they have already “pregnant” with nephritis, which is not easy to “deliver” the fetus. Most nephritis patients are unknowingly attacked by the disease. The onset of the disease is quite insidious, and when the symptoms become apparent there are quite a few days, or even advanced, as in the case of Mr. Ma. This is the “chronic occult nephritis” that is not taken seriously and often ignored by other non-nephrologists. So, how can you find out if you or a loved one has nephritis at an earlier stage? First, it is simple and meaningful: pay attention to your urine! Urine has been described as the “window” of the “department store” of the human body, through which you can know the various products that the company carries. Through the examination of urine, its various changes, you can see the general picture of the kidney. The earliest change of any kidney disease is urine. Nephritis is a lesion of the glomerulus, the basic structure of the kidney. The earliest manifestation in almost all cases is a change in the urine, including a certain amount of proteinuria, red blood cells, or various tubular patterns. Finding these abnormal changes is certainly not necessarily a sign of nephritis, but it is safe to say that it is never inconsequential. From this change, further in-depth examination to clarify the cause of the disease is very important and is a don’t means for early diagnosis. A routine urine test is very simple, as many people know. Although it is said that only a small cup of urine sent to the laboratory will be done, the problem is that people do not pay much attention to it, coupled with the fear of trouble, thinking that “small” and do not do it. Once or twice a year, go for a routine checkup, wouldn’t that be great! Second, pay attention to eyelid swelling. In the early days, people with nephritis often wake up in the morning with mild signs of puffiness on their eyelids, and after a period of time (such as a few hours) it subsides, and people often don’t care. This is because the kidneys are diseased and water is stored in the body, and this water tends to accumulate in the more lax areas. The eyelids are the best place to accumulate water, and it is easy to feel it. Of course, sometimes overexertion and staying up late can cause transient eyelid swelling. However, a little attention will distinguish between the real and the fake. If the eyelid swelling is occasional and there is a reason for it, or if you suspect it, you can get a urine test to clarify it and it is not difficult to distinguish. As for the other also accompanied by high blood pressure, facial obvious edema, pale face day by day and other symptoms. But this set of symptoms manifested must have been not early lesions. It may have been checked in the hospital. Those who have not been clearly diagnosed or treated should be diagnosed and treated as early as possible. Finally, it should also be emphasized that not all urine tests with a little abnormality are nephritis or other kidney diseases, so don’t let one abnormality make you feel anxious, otherwise you will turn to the opposite side from the previous carelessness to worry. However, the urine test should be used to further clarify the cause of the urine change, whether it is a temporary functional change or a disease of the kidney parenchyma. If it is the former, obtain a reassurance; if it is the latter, should be diagnosed early and timely prevention and control. Therefore, if there is even a slight abnormality in the urine, we recommend that you keep the first mid-morning urine and do three tests three times in a row; two out of three are normal, especially the last two are normal, and nephritis can be ruled out. Such an examination should be worthwhile.
