What is protein loss disease?

It is well known that in order to maintain health and strength, the human body needs the support of a variety of nutrients and trace elements. Among them, protein is particularly important. Protein is the material basis of life. Without protein, there is no life. Therefore, it is a substance that is closely related to life and various forms of life activities. Proteins are involved in every cell and all important components of the body. This shows its importance. So what harm will protein loss cause to the human body? Let us take a closer look at protein loss.

The reason for the loss of urinary protein is that there is always a certain amount of protein in the blood that is indispensable to human life activities. Some of the protein is filtered into the urine in the glomeruli of the kidneys, but is absorbed back into the blood in the renal tubules. Therefore, if the kidneys function normally, only a small amount of protein will appear in the urine. However, when there is an obstruction in the kidneys and ureters, a large amount of protein will leak out and become proteinuria.

There are many causes of urinary protein. It can be physiological, such as after intense exercise, pregnancy, etc. Physiological urinary protein generally has a low protein content, lasts for a short time or is transient and disappears quickly. Another case is pathological urinary protein, which is caused by physical illness, such as kidney disease: various nephritis, nephrotic syndrome, diseases other than kidneys, such as diabetes, lupus nephritis, purpuric nephritis, hypertension, some tumors, etc.

Inspection method:

1. Qualitative inspection

It is best to perform a urinalysis on the first urination in the early morning, as morning urine is the most concentrated and can exclude postural proteinuria. When collecting urine samples, discard the first part and keep the middle part of the urine. Qualitative examination is only an initial screening examination. Quantitative examination should be further performed for the diagnosis of kidney disease, observation of the condition and determination of therapeutic efficacy.

2. Quantitative inspection

Quantitative analysis of 24-hour urine protein: accurately collect 24-hour urine protein, mix well, and send urine sample for testing.

3. Special inspection

Examinations such as urine protein electrophoresis, urine light chain quantification, urinary system B-ultrasound, renal puncture biopsy, pathological examination, etc. need to be performed according to clinical diagnosis and treatment needs.
