What symptom does proteinuria 3 + have

summary

My old man started to have intermittent proteinuria a few days ago. At the beginning, he didn't care much about it. He didn't have any examination and treatment. After treatment, he's fine now. I'll sort out some symptoms of proteinuria 3 + for your reference.

What symptom does proteinuria 3 + have

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: we should adopt different standard protein diet according to the type of kidney disease and different condition. For chronic renal insufficiency, it can be supplied according to the normal demand, which is 0.8 ~ 1.0 g / kg per day for adults. Protein with high physiological value should be selected, such as egg, milk, fish, lean meat, etc. For patients with nephrotic syndrome without renal function impairment, high protein diet can be provided, with protein of 1.5-2.0 g / kg per day for adults, and high-quality protein can be provided. For patients with increased plasma urea nitrogen, low protein diet is generally appropriate.
