Urinary protein loss is usually caused by acute and chronic nephritis, nephrotic syndrome, tubular injury and other reasons.
1. Acute and chronic nephritis: due to the changes of glomerular basement membrane and podocytes, it can lead to the glomerular filtration barrier function to produce obstacles, and then the protein leakage from the urine, resulting in the loss of urinary protein. Patients usually show symptoms such as hematuria, proteinuria and edema.
2. Nephrotic syndrome: these patients are mainly characterized by large amounts of proteinuria, hypoproteinemia, and the quantitative amount of urinary protein is more than 3.5 grams a day, so the loss of urinary protein also occurs.
3. Renal tubular injury: if long-term abuse of quinolone antibiotics and other nephrotoxic drugs, can cause renal tubular function is impaired, resulting in reabsorption dysfunction. At this time, some of the small molecules of proteinuria can not be reabsorbed, resulting in the loss of urinary protein.
4. other reasons: for example, metabolic syndrome and other diseases, due to the absorption function is reduced, will also lead to the loss of urine protein. Diabetes causes systemic microangiopathy, leading to complications of diabetic nephropathy, which can cause damage to renal function and loss of urine protein.
In conclusion, if you have a loss of urine protein, it is recommended that you go to a regular hospital in time, identify the cause of the disease and follow the doctor’s instructions for active treatment.
