Weight loss injections are reshaping obesity treatment in Australia - but they are often misunderstood as a quick fix.
Under medical supervision, patients can typically achieve 10–23% total body weight loss over 2–3 years, depending on their health profile, lifestyle, and treatment plan.
These medications work by regulating appetite and blood sugar through GLP-1 pathways, helping reduce hunger and increase fullness. However, they do not cure obesity, and stopping treatment commonly leads to weight regain.
Key points to understand:
✔ Results vary based on starting weight, metabolism, and consistency
✔ Long-term success relies on ongoing lifestyle changes
✔ Medical supervision is essential for safety and dose adjustment
✔ Some patients benefit most from combining medical and surgical approaches
While highly effective for many, weight loss injections require a long-term commitment and realistic expectations.
If you’re considering treatment, the most important step is understanding all your options and choosing an approach tailored to your health needs and goals. To explore what’s right for you, book a consultation with Dr Manju today.
