Diabetic Kidney Disease (DKD), also known as diabetic nephropathy, is a complication of long-term diabetes that damages the kidneys' filtering units. High blood sugar levels over time can cause the kidneys to work harder, leading to scarring and reduced function. DKD is a leading cause of chronic kidney disease and kidney failure. Early detection, strict blood sugar control, blood pressure management, and lifestyle changes can help slow the progression of the disease. DKD is one of the leading causes of kidney failure globally. Early detection and management of blood sugar and blood pressure are critical to slowing the progression of kidney damage. High blood sugar levels caused by diabetes can injure the blood vessels (glomeruli) in the kidneys, leading to a progressive loss of kidney function.
