Proteinuria 3 symptoms

summary

My brother is 18 years old. He has three plus signs in his urine. After treatment, he has recovered a lot. Let's talk about the symptoms of proteinuria 3.

Proteinuria 3 symptoms

Symptom 1: the urine of normal people contains very trace protein, and the routine examination is negative. However, if the glomerular function changes caused by renal disease, resulting in the increase of glomerular filtration membrane permeability, the protein in glomerular filtrate will increase, which will exceed the renal tubular reabsorption capacity and lead to urinary protein dominated by albumin.

Symptom 2: massive proteinuria is the main sign of nephrotic syndrome. The main component is albumin, which also contains other plasma protein components. The change of glomerular basement membrane permeability is the basic cause of proteinuria. The change of charge barrier and mechanical barrier (glomerular capillary pore barrier), the ability of reabsorption and catabolism of renal tubular epithelial cells also affect the formation of proteinuria.

Symptom 3: normal people excrete about 40-80 protein from urine every day, the upper limit is not more than 150 mg, of which the main protein is albumin, followed by glycoprotein and glycopeptide. About 0.60% (60%) of these proteins came from plasma, and the rest came from secretion and tissue decomposition products of kidney, urinary tract and prostate, including urinary enzymes, hormones, antibodies and their degradation products.

matters needing attention

Warm reminder: the occasional urinary protein plus sign, one plus sign or two plus signs, may be due to the recent overwork, or eating high protein food, may also be due to the decline of renal filtration capacity, although this time is accidental, but also can not be careless, we must pay attention to diet, timely to the hospital, to find the root cause of urinary protein Because of treatment, and to regularly review.
