We Answered Your Questions Live on Radio – Here’s What You Asked
Recently, Dr Siva Gounder, lead bariatric surgeon at Perth Weight Loss and Surgery, joined Simon Beaumont live on 6PR Radio to answer your most common questions about obesity, weight loss, and surgical options. The phones lit up with curiosity, concerns, and heartfelt stories, showing just how many people are still unsure where to turn, or whether it’s time to take that first step.
If you missed it, we’ve recapped the key moments below, and yes, you can still listen to the full segment on our website.
Is weight loss surgery safe, and does it actually work?
Dr Gounder was quick to reassure listeners that bariatric surgery isn’t new; in fact, it’s been used successfully for over 40 years and remains the most effective treatment for obesity today. While new medications like Ozempic are now in the mix, surgery continues to deliver the best long-term outcomes for those who qualify.
And yes, it works – for most people, extremely well.
“Patients can lose anywhere between 20 to 70 kilos depending on their situation,” Dr Gounder explained. “The key to success is what happens after surgery. The surgery gives you the tool – but it’s the lifestyle change that locks in the results.”
How do I know if I’m eligible?
Dr Gounder explained the guidelines used nationally and internationally for surgery eligibility:
- A Body Mass Index (BMI) over 35
- Or a BMI between 30–35 with a weight-related condition like Type 2 diabetes, fatty liver, sleep apnoea, or hypertension
He also reminded listeners that surgery is available to patients aged 18–70 in most private hospitals, and that each case is assessed individually depending on medical comorbidities and risks.
“Is there support after surgery?”
One of the most common myths about bariatric surgery is that it’s a ‘set and forget’ solution. In reality, the best results come from consistent follow-up and support.
“We’ve built a multidisciplinary team that includes dietitians, exercise physiologists, and psychologists because patients need long-term support,” Dr Gounder shared. “The one-year and two-year follow-ups are especially powerful. That’s when you see people walk in with a new wardrobe, full of energy, living with less medication and more confidence.”
Real Questions from Real People
Listeners called and texted in with personal stories and concerns. Here are just a few standouts:
- Caller Kate: My friend has had multiple surgeries but keeps regaining the weight – is that normal?
Dr Gounder answered honestly: “Surgery works for most – about 80% – but some people need a second operation or additional support. Often, it comes down to lifestyle habits. That’s why we place such importance on long-term care and accountability.” - Caller Jerry: What are the risks involved?
“All surgery comes with risk,” Dr Gounder acknowledged, “but major complications are less than 1%. Most can be managed with early follow-up. That’s why we keep patients close and test for deficiencies proactively.” - Text from Ivan: How much does it cost?
“If you’re privately insured, out-of-pocket costs range between $4,500 and $5,000. Without insurance, it’s closer to $20,000–$22,000. For some, superannuation access is possible. Medicare covers very little, but private insurance providers must cover bariatric surgery on top-tier policies.”
Lifestyle Change That Lasts
Perhaps the most powerful message from the segment came at the end: surgery helps reduce hunger, cravings, and portion sizes, but it’s your mindset and behaviour that sustain those results.
“It cuts the noise in your head,” Dr Gounder said. “That constant desire to eat junk food goes quiet. Most patients are surprised by how natural it feels to choose nutritious foods again.”
