Experts from Qingdao Jingkang Traditional Chinese Medicine and Nephrology Hospital pointed out:

The main reason is that the glomerular basement membrane is damaged, causing protein leakage.

In clinical work, patients often ask the doctor anxiously with the test sheet. There is protein in their urine. What is going on? The doctor should patiently give a satisfactory explanation to the patient and persuade him. Thoughts attach importance to. Normal people's original urine contains 2 to 4 grams of protein every day, mainly albumin, but most of it has been reabsorbed by the renal tubules, so the excretion of protein in the urine is very small. Healthy adults excrete only 40 to 80 mg of urinary protein every day, so routine qualitative examinations give negative results.

Proteinuria is divided into physiological and pathological properties. Physiological proteinuria is the protein excreted in the urine of normal people every day, with an upper limit of 200 mg. Pathological proteinuria is an increase in protein in the urine and increased excretion. The daily urinary protein excretion exceeds 200 mg, and the urine protein test shows a positive result. Proteinuria is related to most kidney diseases and is an objective indicator of kidney disease.
