Diabetic Kidney Disease (DKD), also known as diabetic nephropathy, is a serious complication of diabetes that gradually impairs kidney function. High blood sugar levels damage the tiny blood vessels in the kidneys, leading to protein leakage, reduced filtration, and progressive kidney decline. Early detection through routine urine and blood tests is essential to slow disease progression. Management focuses on strict blood sugar and blood pressure control, lifestyle modifications, and regular monitoring to prevent complications. In advanced stages, interventions like dialysis or kidney transplantation may become necessary to maintain kidney health and overall well-being.
