Nephrosclerosis is primarily caused by uncontrolled hypertension, which leads to the hardening and thickening of the blood vessels in the kidneys. This condition occurs when high blood pressure damages the small blood vessels, resulting in decreased blood flow and oxygen to kidney tissues. Over time, the affected areas undergo a fibrotic process, diminishing kidney function and potentially leading to chronic kidney disease.

While uncontrolled diabetes can also contribute to kidney damage, it primarily leads to diabetic nephropathy rather than nephrosclerosis. Heart disease, while potentially related to kidney health through vascular complications, does not directly cause nephrosclerosis. High protein intake may be a concern for individuals with existing kidney issues, but it is not a primary cause of nephrosclerosis. Understanding this distinction is crucial for effectively managing and treating patients who may be at risk for kidney complications associated with high blood pressure.
