What is a Gastric Balloon and How Does It Work?
A gastric balloon is a non-surgical weight-loss procedure involving the insertion of a soft silicone balloon into the stomach. Once positioned, the balloon is inflated with saline solution, reducing stomach capacity. This helps you feel full faster, limiting food intake, and supporting healthy weight loss.
A Safe and Effective Weight Loss Option
The gastric balloon is a trusted, medically supervised procedure offering a safe and non-invasive approach to weight loss. It supports steady, gradual weight reduction by helping you feel fuller sooner, encouraging healthier eating habits. Performed under careful medical oversight, this procedure includes regular monitoring by experienced healthcare professionals, ensuring safety and effectiveness throughout your weight loss journey.
The Gastric Balloon Procedure: Step-by-Step
- Pre-Procedure Assessment
You’ll have a full medical review and consultation to ensure the gastric balloon is the right option for you. This includes discussing your weight loss goals, medical history, and any potential risks. - Preparation for the Procedure
You’ll be asked to fast (no food or drink) for several hours before your appointment. The procedure is typically performed as day surgery, and no incisions are required. - Sedation and Endoscopic Placement
Under light sedation, a thin, flexible tube with a camera (endoscope) is passed through your mouth, down your throat (oesophagus), and into your stomach. This allows the medical team to position the balloon accurately. - Balloon Inflation
Once in place, the balloon is filled with sterile saline (salt water) until it partially fills your stomach. This helps you feel full sooner and eat smaller portions. - Recovery and Discharge
The procedure usually takes 20–30 minutes. After a short observation period, most patients go home the same day. You’ll receive dietary and lifestyle guidance to support your success. - Follow-Up Care
Ongoing support from your clinical team, including dietitians and doctors, is vital. The balloon remains in place for up to 6 months, after which it is removed in a similar procedure.
How Much Weight Can You Lose with a Gastric Balloon?
Weight loss results vary from person to person. The gastric balloon is a temporary tool that supports lifestyle and dietary changes. When used alongside a structured program including medical supervision, nutritional support, and behavioural guidance, many people experience a meaningful reduction in weight.
The degree of weight loss depends on individual factors such as starting weight, commitment to healthy habits, and how well the aftercare plan is followed. Your healthcare provider will guide you through what to expect and how to achieve the best outcomes safely.
Recovery and Life After a Gastric Balloon
At Sunshine Coast Medical Weight Loss Centre, we prioritise personalised care and informed decision-making. While we do offer gastric balloons, our surgeon takes a considered approach and only performs this procedure in cases where it may be appropriate.
This is because, in our experience, not all patients respond well to the gastric balloon, and some encounter ongoing issues. That said, we understand that every individual’s needs are different — and for the right person, it may still be a useful option as part of a broader weight management plan.
We encourage you to book a consultation so we can explore your goals, answer your questions, and discuss the most suitable options for your journey with clarity, care, and professional honesty.
Why Choose Sunshine Coast Medical Weight Loss Centre?

Our experienced surgeon approaches the gastric balloon with clinical caution, as not all patients tolerate it well or achieve the desired outcomes. For this reason, we only recommend it when clearly indicated and after thorough consultation.
Choosing our centre means you’ll receive comprehensive support — not just a procedure. From initial assessment through to aftercare, we focus on sustainable results and your long-term health. If you’re considering a gastric balloon, we welcome you to book a consultation so we can discuss whether it’s the right choice for you.
