What does proteinuria 500 mean

summary

After the physical examination, the doctor said that my other physical indicators are very normal, that is, the urine protein is a little high, and now it is finally cured. Today I will share with you what the urine protein 500 means.

What does proteinuria 500 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: if the general urine volume is normal, anuria oliguria and renal failure, should eat vegetables, fruits, in order to provide adequate vitamins. If the patient's urine volume is reduced, especially when less than 500 ml per day, they should selectively eat vegetables and fruits. Because vegetables, fruits are generally rich in potassium, and kidney disease patients with oliguria, serum potassium levels are increased. Blood potassium is too high, can cause cardiac arrest, life-threatening. Vegetables, fruits and cereals are all rich in potassium, among which the fruits with higher potassium content are watermelon, banana, pineapple, mango, jujube, muskmelon, etc.; the vegetables with higher potassium content are amaranth, spinach, celery, carrot, bamboo shoot, potato, etc.
