Diabetic nephropathy, as the name suggests, is a complication caused by diabetes that leads to kidney problems. The typical symptoms of diabetic nephropathy are significant proteinuria and hypoalbuminemia. Generally speaking, there is no particularly effective treatment for diabetic nephropathy; it can only be managed by keeping blood sugar and blood pressure under control. For patients with diabetic nephropathy, it is recommended to keep fasting blood glucose below 7, and postprandial glucose should be controlled between 8 and 10, which is considered appropriate. If hypertension is present, blood pressure should be kept below 140/80 mmHg. In terms of diet, patients with diabetic nephropathy definitely should not drink alcohol, and they should avoid sweets, fried foods, and foods high in starch. It is also important not to stay up late.
