Complications of diabetes can develop without any sign or symptom, and their progress could be slow. Because most complications cannot be completely cured, their prevention is very important. Appropriate monitoring of diabetes-related complications should include management of blood pressure and blood glucose, regular check-ups of the feet and eyes, and assessment of renal and cardiovascular function. It is very important to maintain quality of life for diabetes patients through the early detection and treatment of complications. For that, diabetic patients should check blood sugar levels and other signs and symptoms of complications by visiting the doctor's office regularly.
