To prevent or delay the progression of diabetic nephropathy in patients with type 1 and type 2 diabetes, a multi-faceted approach is essential. This approach includes smoking cessation, maintaining a healthy weight, and achieving optimal glycemic control, potentially supported by intensive diabetes treatment strategies. Recent advancements in antidiabetic pharmacotherapy have shown that certain medications offer significant protective effects on kidney function beyond blood sugar control. Furthermore, rigorous management of blood pressure and cholesterol levels plays a critical role in reducing the risk and slowing the progression of this condition.
