Your fasting blood sugar of 80-90 mg/dL is within the normal range, and a 2-hour post-meal level of 145-180 mg/dL can be slightly high but does not always confirm diabetes by itself. It is best to check tests like HbA1c or fasting and post-meal blood sugar regularly and review them with your doctor. Maintaining a healthy diet, regular physical activity, weight control, and limiting sugary or high-carbohydrate foods can help keep your blood sugar stable. Since you have other medical conditions and are taking other medicines, it is important to discuss your results with your doctor for proper evaluation and guidance.

Swelling in the leg by evening that improves by morning can happen due to prolonged sitting or standing, poor circulation, or sometimes as a side effect of blood pressure medicines. Try to avoid sitting for long hours, keep your legs slightly elevated while resting, and reduce excess salt in your diet. Since you have diabetes and high blood pressure, it is important to consult your doctor to check the swelling and adjust medicines if needed.
