What symptom is albuminuria again

summary

Urine protein test a plus sign doctor said that he was afraid of kidney problems. After treatment, he was better. Let's take a look at the symptoms of urine protein.

What symptom is albuminuria again

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: nephrotic syndrome (NS) can be caused by a variety of causes, mainly the increase of glomerular basement membrane cell permeability in patients, generally manifested as a large amount of proteinuria, hypoproteinemia, metabolic hyperedema and hyperlipidemia.
