Common Sense of Nephropathy | Is Normal Renal Function Good for Nephropathy? The real situation is much worse than you imagined

Some time ago, I saw a kidney friend leave a message: Doctor, is it possible to rule out kidney disease if the renal function indicators are normal I often see patients in my circle of friends who have also shown their own test indicators, which also means something similar.

Many people now understand that this kidney is the most "hardworking" organ in the human body. Specifically, each kidney consists of nearly 1 million nephrons, which have the functions of excreting metabolic products, regulating the stability of the human body's internal environment, and regulating endocrine secretion. Due to the vulnerability of the kidney to drugs, inflammation, external forces, and other damage, it has formed a strong reserve capacity during human evolution, and minor lesions are not easy to manifest.

Therefore, a topic has also been raised: Normal renal function can exclude kidney disease. In fact, this is also a common sense of treatment among many kidney friends.

Why does this consciousness arise? I think a large part of the reason lies in the fact that Western medicine treats everything with a goal orientation. As long as the indicators are normal, the disease is considered to be cured. Unexpectedly, many times the goal of treating the root cause is not achieved, even delaying the diagnosis and treatment of the disease at the beginning.

Here, let's first solve this problem for everyone. What exactly are the renal function indicators?

In medicine, urine microscopy and chemical tests, as well as certain chemical tests of blood, are commonly used to measure changes in renal function. Renal function tests include blood creatinine, blood urea nitrogen, blood and urine β 2 - Microglobulin, urinary albumin, urinary immunoglobulin G, urinary secretory immunoglobulin A.

Currently, the most commonly used method for testing renal function is to measure the levels of serum urea nitrogen and creatinine. When the nephron is damaged by about 50%, the test results are still normal, and when the damage exceeds 50%, the abnormal increase will occur. In other words, a normal renal function test does not necessarily mean that the kidney is not defective.

Remember, this is about kidney damage exceeding 50%.

In fact, only when the damage to the kidney exceeds 50% can it lose its compensatory capacity, which can lead to symptoms of renal failure. At the same time, unlike hepatocytes, nephrons do not regenerate, and poor liver function can be restored through liver protection therapy. However, if nephrons are damaged one by one, they will become "debilitating" once they lose their compensatory capacity.

Therefore, kidney disease is often insidious, usually without obvious discomfort. When some people experience symptoms, renal function damage has progressed to uremia, which is also the most frightening aspect of kidney disease! In addition, during the treatment and maintenance process, do not trust the detection indicators too much. Regular review, actively cooperate with the doctor, and follow the doctor's instructions are the king's way!

In short, even if it is found that renal function is normal, kidney disease cannot be ruled out. In order to be responsible for your own body, I suggest that you conduct further examinations to determine the specific situation of your body.
