Non-Surgical Weight Loss Alternatives – Injections

In Australia, the primary weight loss medications currently approved for use include Saxenda® (liraglutide), Wegovy® (semaglutide), and Contrave® (bupropion/naltrexone). These medications work in different ways to help regulate appetite, increase satiety (the feeling of fullness), or reduce food cravings. Saxenda and Wegovy are part of a class of drugs known as GLP-1 receptor agonists, which mimic a natural hormone that affects appetite and digestion. Contrave, on the other hand, acts on the brain to influence hunger and reward centres. These medications are prescribed as part of a broader weight management plan that includes dietary changes, increased physical activity, and behavioural strategies. They are not magic pills, but powerful tools when used appropriately under medical supervision.

Weight loss medications in Australia are generally prescribed for individuals with a body mass index (BMI) of 30 or above, or 27 and above with an obesity-related health condition, such as type 2 diabetes, high blood pressure, or sleep apnoea. However, eligibility isn’t determined by BMI alone. A specialist bariatric team considers your full health profile, lifestyle, previous weight loss attempts, and the potential risks or benefits of medication. Not every patient is suited to medication – some may benefit more from surgery or lifestyle intervention alone. A consultation at Perth Weight Loss and Surgery ensures that your options are matched to your individual health goals and circumstances.

GLP-1 receptor agonists are a class of medications originally developed to treat type 2 diabetes but have proven highly effective in supporting weight loss. They mimic a hormone called glucagon-like peptide-1 (GLP-1), which helps regulate appetite and slows down digestion, so you feel full sooner and for longer. Saxenda and Wegovy are administered via daily or weekly injections, respectively. Their popularity stems from clinical trial results showing significant and sustained weight loss in many patients. When prescribed appropriately and used alongside a supportive care plan, they can offer a non-surgical alternative for people who need help managing obesity and its related conditions.

Not necessarily. Weight loss medications can be a helpful alternative for patients who either do not qualify for surgery, are not ready to consider it, or prefer a non-invasive approach. However, they generally produce less weight loss than bariatric procedures such as gastric sleeve or bypass surgery. They may be used to support pre-surgical weight loss, improve eligibility for surgery, or help patients maintain weight loss after surgery. At Perth Weight Loss and Surgery, we view medication as one of several tools available to support patients on their journey to better health. The right solution is based on your medical history, goals, and what you’re comfortable with.

Yes, like all medications, weight loss drugs come with potential side effects. The most common with GLP-1 receptor agonists (like Saxenda or Wegovy) include nausea, vomiting, diarrhoea, constipation, and headaches – especially when starting treatment. These symptoms usually ease over time. Contrave may cause dizziness, dry mouth, and insomnia. In rare cases, serious complications can occur, including pancreatitis or gallbladder issues. For this reason, ongoing medical supervision is essential. At Perth Weight Loss and Surgery, our team will carefully assess your suitability for medication and monitor your progress closely to minimise risks and manage any adverse effects promptly.

The duration of treatment varies significantly depending on individual response, goals, and whether any side effects arise. Some patients use weight loss medication for several months to kickstart their progress, while others may remain on it for 12 months or longer. Long-term use may be appropriate for those with chronic obesity and related health conditions. Importantly, weight maintenance after medication cessation is more likely when it’s combined with long-term dietary and behavioural changes. Perth Weight Loss and Surgery offers integrated support throughout your treatment, including dietetics, psychology, and medical monitoring, to help you build sustainable habits that last beyond the prescription.

Absolutely. In fact, weight loss medications are most effective when combined with a comprehensive care plan. This may include dietary counselling, exercise programs, behavioural therapy, and, in some cases, bariatric surgery. For patients undergoing surgery, medication can be used pre-operatively to reduce surgical risk or post-operatively to help maintain results. At Perth Weight Loss and Surgery, we take a multidisciplinary approach to your care. Your treatment plan is tailored to your needs, whether you’re taking the first steps toward weight loss or need help sustaining your post-surgical success.

At present, weight loss medications such as Saxenda®, Wegovy®, and Contrave® are not subsidised under the Pharmaceutical Benefits Scheme (PBS), meaning they are not covered by Medicare. This means patients must pay the full retail price, which typically ranges from $300 to $500 per month, depending on the type and dosage prescribed. These costs are in addition to consultation and support services. Most private health insurance policies do not cover the cost of weight loss medication either, although some may contribute to related allied health services such as dietitian support. For example, at Perth Weight Loss and Surgery, a consultation with our in-house dietitian is $90 (with or without a referral), which may be eligible for a rebate depending on your level of extras cover. To get started on medication, we offer a dedicated weight loss prescription consultation with Dr Gounder for $180, where eligibility, treatment suitability, and support pathways will be discussed. We always provide transparent information upfront to help patients make informed decisions, including guidance on budgeting for your weight loss plan. If cost is a barrier, we’ll work with you to explore all appropriate treatment options, whether surgical (which may be bulk billed) or behavioural, to ensure you’re supported in a safe, sustainable, and financially considered way.

There is a risk of weight regain if healthy habits aren’t maintained after stopping medication. This is because weight loss medications help regulate appetite and satiety, and when that assistance is withdrawn, old habits can easily return. However, this is not inevitable. Patients who adopt lasting changes in diet, exercise, and mindset during their time on medication are much more likely to maintain their results. Perth Weight Loss and Surgery focuses on long-term support, helping patients develop realistic, maintainable routines that don’t rely solely on medication. With the right follow-up care, it is absolutely possible to keep the weight off.

To begin, simply book a weight loss prescription consultation with Dr Gounder for $180 – no referral is needed. During this appointment, we’ll assess your suitability for medication, review your medical history, and discuss your goals. If you proceed, our team will guide you on proper medication use, side effect management, and how to integrate it with diet and lifestyle changes. We may also recommend a dietitian consultation ($90) to further support your treatment. Whether you’re new to weight loss efforts or exploring non-surgical alternatives, we’re here to help you take the next step with confidence and care.
