What is the Most Likely Cause of Protein in Urine

Question

What is the most likely cause of protein in urine?
A) High pressure within the glomerulus
B) Damaged glomerular capillaries
C) High-protein diet
D) Protein is a normal finding in urine

Accepted Answer

Proteinuria, or the presence of protein in the urine, is most commonly caused by damage to the glomerular capillaries in the kidneys. This damage can be a result of various conditions such as kidney disease, hypertension, diabetes, infections, and autoimmune disorders. High pressure within the glomerulus can also cause proteinuria, but it is usually a result of underlying conditions that cause the increased pressure. A high-protein diet may also temporarily increase the amount of protein in the urine, but it is not the primary cause of persistent proteinuria. Protein is not a normal finding in urine and should be investigated by a healthcare provider.
