Proteinuria can result from various conditions affecting the kidneys:
Diabetic Nephropathy: High blood sugar levels can damage the glomeruli over time, leading to protein leakage. Hypertension: High blood pressure can cause scarring in the kidney tissues, impairing their filtering capability. Glomerulonephritis: Inflammation of the glomeruli can increase permeability, resulting in proteinuria. Polycystic Kidney Disease: Genetic disorders can disrupt normal kidney function, leading to proteinuria. Lupus Nephritis: Autoimmune diseases like lupus can affect kidney function and cause proteinuria.
