What does proteinuria mean

summary

Lumbago more than 2 years, sometimes have proteinuria +, lumbago ache, make water is very hot sometimes, after treatment apparent person is much better, so, what meaning is proteinuria? You know what? Today, let me share with you the meaning of urinary protein.

What does proteinuria mean

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: warm reminder: adopt low protein diet (protein intake ≤ 0.8g or 0.6g / kg / D); provide essential amino acids to overcome the malnutrition of low protein diet and greatly reduce the excretion of proteinuria. Through symptomatic treatment, kidney repair treatment and comprehensive diet control, not only can reduce the patient's urine protein, but also can effectively prevent the advent of end-stage renal failure, which has an important role in improving the quality of life of patients.
