Key points

Diagnosis
- HbA1c ≥48 mmol/mol on two occasions, or
- Fasting glucose ≥7.0 mmol/L, or
- Random glucose ≥11.1 with symptoms.

Lifestyle
- Weight loss — 10–15kg loss can put diabetes into remission.
- Mediterranean or low-carb dietary patterns work.
- Aerobic + resistance exercise.
- Stop smoking; limit alcohol.
Medication
- Metformin: first-line. Reduces glucose, modest weight loss, cardiovascular benefit.
- SGLT-2 inhibitors (dapagliflozin, empagliflozin): good for heart and kidney protection.
- GLP-1 agonists (semaglutide, dulaglutide, tirzepatide): excellent glucose control + significant weight loss.

- Insulin: if other treatments insufficient.
Targets
