Proteinuria found on the medical checklist means severe kidney damage? Reminder: The real worry is this

In a healthy human body, there are two kidneys located on both sides of the lower abdominal cavity. Affected by the promotion of health products and traditional Chinese medicine, many people mistakenly believe that the kidney is the organ that dominates "sex".

But in fact, there is no essential relationship between kidney function and sex. Its real role is to detoxify and balance, and through it, urine is generated to maintain the balance of water, electrolytes and blood pressure in the body.

From a clinical point of view, the basic function of the kidneys is to produce urine! In the process of kidney examination, the most basic test is the "urine test".

According to clinical data research, the most likely symptom of chronic kidney disease in the early stage is "proteinuria", which means that urine contains a large amount of protein, and proteinuria is also an independent risk factor for the development of kidney disease to kidney failure!

Long-term large amounts of proteinuria will cause glomerular hyperfiltration, promote the continuous sclerosis of the glomeruli, and lead to a continuous decline in renal function. Therefore, patients with chronic kidney disease are very concerned about the test value of "urinary protein". When they find that the urine protein is elevated and a + sign appears, they will worry that they have renal failure!

Proteinuria+ is actually not as scary as everyone imagines!

Clinically, proteinuria can be divided into two cases. One is physiological proteinuria, which usually occurs in people who have a high-protein diet, mental agitation, and after strenuous exercise. This kind of temporary proteinuria does not need to be overly concerned.

What really needs to be vigilant is the proteinuria in patients with chronic kidney disease. Under normal circumstances, proteinuria has at most 4 plus signs;

The more proteinuria plus signs appear, the more severe the symptoms will be. However, in the process of clinical treatment of nephropathy, the examination of urine protein is not as important as imagined. Because there are many interference factors in urine routine, the standard for quantitative evaluation of total urine protein is not a routine urine examination. Doctors pay more attention to 24-hour proteinuria quantification!

Therefore, what really needs patients to be vigilant is the 24-hour urine protein quantification!

This is not easily affected by the amount of drinking water and urine. The 24-hour urine protein quantification of normal people is less than 150mg, usually between 40-80mg. Occasionally, the 24-hour urine protein quantitatively exceeds the standard, and it cannot be diagnosed as kidney disease; only after multiple examinations, three or more 24-hour urine protein exceeds the normal range, can it be judged that the kidney has lesions!

In addition, urine protein itself can not accurately reflect the degree of kidney damage, nor can it be used as a criterion for judging whether the efficacy is good or bad. Routine urinalysis is only an examination method to assist diagnosis. The reason for the high frequency is that routine urinalysis is more convenient and fast, and the most important thing is that it is cheap!

In addition to observing urine protein, patients also need blood vessels to check plasma albumin!

For patients with renal disease, especially those with nephrotic syndrome, we must learn to observe the stability of plasma albumin. Because of long-term proteinuria, it is very easy to reduce plasma albumin and induce hypoalbuminemia.

This will not only cause high edema, but may also develop into multiple problems such as cardiopulmonary failure, deep vein thrombosis, and low immunity!

In fact, there are many clinical examination methods for kidney disease, and urine protein is only one of the warning signals issued by the body.

However, in patients with chronic kidney disease, the continuous increase of urinary protein is a dangerous situation. Actively communicate with the attending doctor, adjust the treatment plan, and avoid further development and deterioration of the disease, which will have a greater impact on the body.
