With an average blood sugar of 163 mg/dL and a HbA1c of 7.3%, your diabetes control is fair but still marginally beyond the optimum target. Metformin is helping, but in order to further improve your blood sugar, you might require more stringent dietary restrictions, frequent exercise, weight control, and appropriate meal time. Walk for at least 30 to 45 minutes every day and try cutting back on sweets, sugar-filled beverages, extra rice, and fried foods. For improved long-term protection of the eyes, kidneys, nerves, and heart, many clinicians strive for a HbA1c below 7%, though goals may vary depending on age and medical condition. Keep taking your medications as prescribed, and talk to your doctor about whether you need to add more medication or change your dose.
