For people living with obesity, choosing the right treatment for sustainable, long-term weight loss is a significant decision. Two of the most commonly discussed options are Ozempic (semaglutide) a medication originally used for type 2 diabetes but now frequently prescribed off-label for weight loss and bariatric surgery, a surgical approach designed to support long-term weight management.
What Is Ozempic?
Ozempic is a prescription medicine containing semaglutide, a GLP-1 receptor agonist used to help manage blood sugar levels in adults with type 2 diabetes. Although approved by the TGA for the treatment of type 2 diabetes, many doctors also prescribe it off-label for patients with obesity who haven’t had success with diet and exercise alone.
Semaglutide works by mimicking a naturally occurring hormone that regulates appetite, blood sugar, and digestion. It slows down how quickly food leaves the stomach and reduces hunger, which can lead to lower calorie intake and gradual weight reduction.
Note: Ozempic is not available over the counter. It’s a Schedule 4 prescription-only medication, requiring a script from a registered doctor and pharmacist supervision for safe use. A related semaglutide product, Wegovy, has been approved overseas for weight loss but is not yet available in Australia.
Cost of Ozempic in Australia
As of 2025, the cost of Ozempic ranges from: $130 to $200 per month, depending on the dose and pharmacy. This equates to $1,560 to $2,400 per year if used continuously. Ozempic is not subsidised by the PBS (Pharmaceutical Benefits Scheme) when used for weight loss, so patients must pay the full price.
Effectiveness of Ozempic
Clinical studies suggest that individuals using semaglutide may lose up to 10–15% of their body weight over time. However, weight loss typically requires continued medication use and lifestyle changes to be sustained.

What Is Weight Loss Surgery?
Also known as bariatric surgery, weight loss surgery involves modifying the digestive system to help limit food intake or absorption. It’s generally considered when non-surgical options have not led to sufficient weight loss or health improvement. Eligibility is usually based on a Body Mass Index (BMI) of 40 or higher, or a BMI of 35 or more in individuals with obesity-related conditions such as type 2 diabetes or sleep apnoea. A comprehensive assessment by a weight loss doctor or bariatric surgeon is required to confirm suitability.
Common procedures include:
- Gastric Sleeve: Removes a portion of the stomach to reduce capacity
- Gastric Bypass: Alters the stomach and small intestine to reduce absorption
- Gastric Banding: Places an adjustable band around the upper stomach (now less commonly performed)

Cost of Bariatric Surgery in Australia
Prices vary by procedure, location, and health insurance coverage. As a general guide:

Effectiveness of Weight Loss Surgery
Bariatric procedures are often highly effective for sustained weight loss and long-term health benefits:
- 50–70% of excess weight lost within 1–2 years
- Improvements in conditions like type 2 diabetes, hypertension, and sleep apnoea
Ozempic vs Weight Loss Surgery Cost Comparison
| Cost Factor | Ozempic (Semaglutide) | Bariatric Surgery |
|---|---|---|
| Initial Cost | $130–$200 per month | $12,500–$20,000 (one-time) |
| Annual Cost | $1,560–$2,400 | Included in upfront fee |
| 5-Year Cost Estimate | $7,800–$12,000 | $12,500–$20,000 |
| 10-Year Cost Estimate | $15,600–$24,000 | $12,500–$20,000 |
| Rebates/Subsidies | Not covered for weight loss | May be covered by private insurance |
| Ongoing Costs | Repeat prescriptions, GP visits | Check-ups, dietitian, supplements |
Ozempic may seem budget-friendly at first, but the cumulative cost over time can far exceed the cost of a one-time surgical procedure. In fact, over a 5–10 year period, patients may spend twice as much on Ozempic, with no guarantee of long-term success.
Short-Term vs Long-Term Weight Loss Results
| Outcome | Ozempic | Bariatric Surgery |
|---|---|---|
| Average Weight Loss | 5–15% of total body weight | 20–40%+ of total body weight |
| Time to See Results | Gradual over weeks/months | Rapid—usually within 6 to 12 months |
| Long-Term Maintenance | Requires ongoing medication | Generally long-term without reoperation |
When used off-label for weight loss, Ozempic may not come with a structured care plan or multidisciplinary support. In contrast, bariatric surgery patients are supported by a coordinated team, which can significantly improve outcomes and accountability.
Choosing the Right Option for Sustainable Weight Loss
Ozempic may seem appealing because it’s non-surgical and offers short-term weight loss. However, when considering the long-term financial cost and the likelihood of weight regain, it may not be the most effective option forward. Bariatric surgery, while involving an upfront investment and recovery period, provides a durable, cost-effective, and medically supported solution for long-term weight management and overall health improvement.
Before making a decision, it’s essential to consult with a qualified bariatric specialist to discuss your options and determine the most effective approach for your weight loss goals.
