Why Is Urine Protein High When Renal Function Is Normal?
High urine protein with normal renal function may be caused by prolonged intense exercise, long-term medication use, and Nutcracker Syndrome, among other factors.
Prolonged Intense Exercise: Generally, prolonged intense exercise accelerates the body's metabolism, leading to physiological proteinuria. It is necessary to reduce exercise intensity, and generally, medication is not required.
Long-term Medication Use: Long-term use of antibiotics or non-steroidal anti-inflammatory drugs, such as Amoxicillin Capsules, Ibuprofen Tablets, and Paracetamol Tablets, can increase kidney burden, resulting in proteinuria in urine, despite normal renal function. Typically, discontinuation of the medication is needed.
Nutcracker Syndrome: It may be caused by a reduction in retroperitoneal fat tissue or a small angle between the abdominal aorta and the superior mesenteric artery. Typical symptoms include orthostatic proteinuria and hematuria, which usually do not cause glomerular damage. Following doctors' advice, medications such as Aspirin Enteric-coated Tablets, Hydrocortisone Acetate Tablets, and Captopril Tablets may be prescribed.
In addition to the above reasons, it may also be due to chronic glomerulonephritis, nephrotic syndrome, diabetic nephropathy, and other causes, which require medical attention.
