With all the hype around GLP-1 medications, it's natural to wonder: do I actually need this? Here's a framework for thinking it through.
Consider medication if...
- Your BMI is ≥30 (or ≥27 with a health condition like diabetes, high blood pressure, or sleep apnoea)
- You've tried sustained lifestyle changes (diet + exercise) for at least 6 months without achieving meaningful results
- Your weight is affecting your health — blood sugar, blood pressure, joints, sleep, or daily functioning
- You understand that medication is a long-term commitment, not a quick fix
- You can afford the ongoing cost (or may qualify for PBS)
Medication may not be right if...
- You're at a healthy weight and want to lose a small amount for cosmetic reasons
- You haven't tried consistent lifestyle changes yet — medication works best alongside diet and exercise, not instead of them
- You have contraindications (pregnancy, certain thyroid conditions, history of pancreatitis)
- You expect medication to do all the work — it's a tool, not a complete solution
- The cost would cause significant financial stress
Questions to ask your doctor
- Based on my health profile, would I benefit from weight loss medication?
- Which medication would you recommend for my situation, and why?
- What results should I realistically expect?
- How long would I need to take it?
- What happens if it doesn't work or I can't tolerate the side effects?
The bottom line
Weight loss medication isn't for everyone, but it's no longer a "last resort." For people with clinical obesity or overweight with health complications, it's an evidence-based treatment that can produce meaningful, sustained results. The key is making an informed decision with your doctor.
