Diabetic nephropathy is a kidney condition that can occur in people with diabetes. It happens when high blood sugar levels damage the tiny blood vessels in the kidneys, making it difficult for them to filter waste from the blood. Over time, this can lead to kidney failure if not managed properly. Symptoms of diabetic nephropathy may include swelling in the legs and feet, high blood pressure, and changes in urine output. Regular check-ups and managing blood sugar levels are essential for preventing or slowing the progression of this condition. Early detection can help preserve kidney function and overall health.
