The Magic Pill - What You Might Not Know About Weight Loss Medications

Melissa Beitner • September 18, 2024

Diplomate of the American Board of Obesity Medicine, Dr. Melissa Beitner from 360 SURGERY Melbourne, offers insights into use of semaglutide for weight loss


Touted as a ‘magic pill’ for weight loss, use of semaglutide, often referred to by the brand names Ozempic ® and Wegovy ®, is complex which is fitting for an equally complex disease - obesity.


First things first. Use of Ozempic ® should be done with caution and under medical supervision. Medical supervision means that you are assessed by a medical practitioner who can appropriately prescribe these medications, monitor for side effects and follow your progress - making adjustments along the way, if necessary. You’ll need to have your height and weight checked and check your waist measurement.


Ozempic ® and other GLP-1 agonists like Mounjaro ®, have revolutionised the medical weight loss industry as the first medications to start to bridge the gap between pharmaceuticals for weight management (which have historically had only modest efficacy) and bariatric surgery (the most powerful tool for weight loss). In current studies, using 2.4mg of semaglutide for 68 weeks in conjunction with a reduced calorie diet and increased physical activity resulted in an average of
14.9% reduction in total body weight. We expect the average weight loss at 1 year after bariatric surgery to be 30% or more.


Up to a third of patients on 2.4mg semaglutide lose
20% or more of their body weight after 1 and 2 years on the medication. Approximately half of patients lose 15% or more of their body weight after 1 and 2 years. The other half lost <15%. Some people, 16.5% of patients treated with semaglutide 2.4mg for 68 weeks, lost <5%. This highlights that use of this medication has variable effects. Having realistic expectations for weight loss will help avoid disappointment and guide therapy. If you’re looking to lose 20% or more of your body weight, you might be better suited to surgical weight loss. 


If you’re looking to sustain the weight loss you’ve achieved with Ozempic ® or Wegovy ®, you’ll need to continue to use the medication. Studies have found that one year after withdrawal of semaglutide 2.4 mg and lifestyle intervention, participants regained two‐thirds of their prior weight loss, with similar changes in cardiometabolic variables. Bear this in mind when making the decision to start semaglutide as you’ll likely need to continue it indefinitely in order to continue to see the benefit. Ongoing use will mean you’ll need to have a continuous supply and accept the continuous cost of the medication.

Learn how to manage nausea, cramps, fatigue, and more while using GLP-1
June 26, 2025
GLP-1 receptor agonists such as Wegovy® (semaglutide) and Mounjaro® (tirzepatide) are powerful tools for long-term weight management. They work by regulating appetite, improving insulin sensitivity, and slowing stomach emptying. However, like any medication, they may cause side effects, particularly during the first few weeks of treatment. At 360 SURGERY Melbourne, we help patients achieve their health goals safely and effectively. Here are some practical tips to manage the most common side effects of GLP-1 medications, so you can stay on track with your weight loss journey. 1. Nausea Nausea is one of the most reported side effects of GLP-1 medications, especially when doses are increased. These strategies may help: Eat smaller, more frequent meals : Large meals can trigger nausea. Avoid fatty or spicy foods : These can irritate your stomach further. Stay well-hydrated : Sip water or herbal teas slowly throughout the day. Choose bland foods : Toast, rice, and crackers are easier to tolerate. Take your injection at bedtime : This can reduce awareness of nausea during the day. 2. Diarrhoea This is typically mild and short-term but can be managed with the following tips: Stay hydrated : Replenish fluids and electrolytes to prevent dehydration. Follow a low-fibre diet temporarily : Stick to easy-to-digest foods like bananas, applesauce, rice, and toast (the BRAT diet). Avoid caffeine and alcohol : These irritants can worsen diarrhoea. Try probiotics : They may support gut health and digestive balance. 3. Constipation Constipation may occur as your digestive system adjusts. The following can help: Increase fibre intake : Add fruits, vegetables, and whole grains to your meals. Stay physically active : Regular movement promotes bowel motility. Drink plenty of water : Fluid intake is key for regular bowel movements. Use a fibre supplement : Products like psyllium husk may provide relief. 4. Stomach Pain or Cramps Abdominal discomfort can occur, particularly after meals. Try the following: Eat slowly and chew thoroughly : This supports smoother digestion. Avoid lying down immediately after eating : Wait 1–2 hours before reclining. Use a warm compress : Applying heat to the abdomen may reduce cramping. Consult your doctor if pain persists : Persistent or severe pain may indicate a more serious issue such as pancreatitis. Seek medical review promptly. 5. Headaches Headaches may occur during the adjustment phase and are often linked to hydration or blood sugar changes. Stay hydrated : Dehydration is a common trigger for headaches. Rest in a dark, quiet room : Reduces stimulation and allows recovery. Use over-the-counter pain relief : Paracetamol is generally safe, but check with your doctor. 6. Fatigue or Low Energy Feeling tired or lethargic can be frustrating. These tips may help restore energy: Prioritise good sleep hygiene : Stick to a regular sleep schedule and minimise screen time before bed. Balance activity and rest : Light movement (like walking) can improve energy levels. Monitor blood sugar levels : Hypoglycaemia may occur in some cases—especially if you’re on other medications. Discuss with your doctor if necessary. 7. Injection Site Reactions Mild swelling, redness, or discomfort at the injection site is common. Rotate injection sites : Avoid using the same area repeatedly. Apply an ice pack : Before and after the injection to reduce swelling. Keep the area clean : Prevents infection or irritation. How to Stay on Track with Your GLP-1 Treatment Mild side effects are common and often improve over time.

Learn about out-of-pocket fees, insurance, and financial options for weight loss surgery
June 12, 2025
Navigating the costs of private healthcare—especially for a procedure like bariatric surgery—can feel overwhelming. Even with private health insurance, most patients are surprised to learn that out-of-pocket expenses still apply. This guide helps you understand what you’re likely to pay when undergoing weight loss surgery in Melbourne, and how to prepare financially. Two Categories of Bariatric Surgery Costs To make things easier, we’ll break down the costs into two main areas: Out-of-hospital costs In-hospital costs Out-of-Hospital Costs These are the costs incurre d before you’re admitted to hospi tal and include consultations, referrals, and diagnostic testing. GP and specialist appointments: Medicare covers a portion of these visits, but if your providers charge above the Medicare rebate, you'll be required to pay th e gap (out-of-po cket cost). Non-MBS services: Services s uch as dietitian consultations, psychologist sessions, or physiotherapy may not be listed on the Medicare Benefits Schedule (MBS), meaning you’ll need to pay the full amount. Pre-operative tests: The good news is that most standard blood tests, imaging, and other required diagno stics are typically bulk-billed, especially if referred by your GP or surgeon. In-Hospital Costs These are the costs associated with the surgical procedure and hospital stay. Bariatric surgeon fees: Most surgeons charge a gap fee in add ition to what Medicare or your insurer pays. Anaesthetist and surgical assistant fees: Both may bill separately and usually charge a gap not covered by your insurance. Hospital stay: This is often the most significant cost. The amount depends on your insurance policy—including your excess, co-payments, and whether your hospital is a preferred provider. If you do not have private health insurance, you’ll be responsible for the full cost of the hospital stay, which can range from thousands to tens of thousands of dollars depending on the facility and length of stay. How to Pay Out-of-Pocket Costs (The ‘Gap’) Even if you're insured, you will likely still fac e gap fees. It’s im portant to plan ahead. Here are some common ways to manage these costs: Personal savings: Using your own funds can avoid interest or fees associated with loans. Early release of superannuation: You m ay be eligible to access your superannuation early on compassionate grounds to pay for m edical treatment, including bariatric surgery. This involves applying to the ATO with medical certification. Medical loans and financing: Organisations such as TLC (Total Lifestyle Credit) provide personal loans tailored for medical expenses. These loans can cover surgeon fees, hospital costs, and more. What Is Informed Financial Consent? Before committing to surgery, it’s essential to ask for a written cost estimate from each provider involved in your care. This includes: Your bariatric surgeon The anaesthetist The hospital Any other specialists involved (e.g., physician, dietitian) This process is call ed informed financial consent and ens ures you: Know what you’re paying for Understand what your insurance will cover Avoid surprise bills after surgery Alway s ask questions and clarify anything you don’t understand. Key Takeaways Bariatric surgery in Melbourne involves out-of-pocket costs even if you have private insurance. Costs are divided into out-of-hospital and in-hospital components. Expect to pay gap fees for surgeon, anaesthetist, hospital stay, and any non-MBS services. You can use personal funds, early access to superannuation, or personal loans to manage these costs. Always request informed financial consent with a detailed cost estimate before undergoing surgery. While bariatric surgery is a life-changing investment in your health, it’s important to go in with clear financial expectations. Knowing what’s covered, what isn’t, and how to fund your care ensures a smoother journey to better health.
