Type 2 Diabetes Mellitus usually develops due to a mix of factors like family history, weight, lifestyle habits, and how the body handles insulin, so it is not always possible to pinpoint a single cause. Your current sugar levels (fasting 147 mg/dL and post-meal 174 mg/dL) suggest that control can be improved. Along with continuing your prescribed medicines, the most important step is lifestyle management: follow a balanced diet with less sugar and refined foods (like white rice, sweets, and bakery items), include more vegetables, whole grains, and protein, and eat at regular times. Aim for at least 30 minutes of daily physical activity, such as brisk walking, which helps lower blood sugar naturally. Maintaining a healthy weight, getting good sleep, and managing stress also play a big role. Regularly monitor your blood sugar and have periodic check-ups so your doctor can adjust medicines if needed. Avoid skipping or changing medicines on your own. With the right combination of medication, diet, and exercise, diabetes can be well controlled, and complications can be prevented.
