Urine protein 2+, may be related to excessive protein intake, strenuous exercise and other physiological causes, but also may be related to pre-renal proteinuria, renal proteinuria, post-renal proteinuria and other pathological causes.
1. Physiological reasons: glomerular capillary filtration membrane, tubular reabsorption function together affect the urinary protein, when the intake of excess protein, more than the renal filtration, reabsorption function, can cause urinary protein 2 +. In addition, after strenuous exercise, cold stimulation, as well as urine mixed with leukorrhea, prostate fluid and other protein-containing components can also cause urinary protein 2 +.
2. Pathologic causes
(1) Pre-renal proteinuria: when the body suffers from myeloma, paroxysmal sleep hemoglobinuria, myocardial infarction, pancreatitis and other diseases, it can cause the protein in the blood to be elevated, which exceeds the glomerular filtration threshold and causes urinary protein 2+.
(2) Renal proteinuria: when the body suffers from nephrotic syndrome, acute nephritis, diabetic nephropathy, interstitial nephritis and other renal diseases, or heavy metal poisoning, drug poisoning and so on may cause renal filtration or reabsorption function abnormality, resulting in urinary protein 2+.
(3) Post-renal proteinuria: when the body suffers from cystitis, urethritis, urinary stones, etc. can also appear urine protein 2 +.
When there is urine protein 2+, it is recommended to go to the hospital in time to clarify the cause under the guidance of the doctor, and active treatment.
