Obesity is a serious and rising health concern in Australia, with one in three adults now considered obese. For many Brisbane residents, the struggle to lose weight through diet, exercise and medications alone can be disheartening. Obesity surgery, also known as bariatric surgery, offers a medically supported, long-term option for those looking to improve their health and quality of life.

At Brisbane General & Obesity Surgery (BGOS), we offer comprehensive weight loss solutions tailored to the individual. This article will guide you through the different obesity surgery options available in Brisbane, explain the potential benefits, and provide insight into the patient care journey—from your first consultation to life after surgery.

What Is Obesity Surgery?

Obesity surgery involves a variety of procedures designed to help individuals lose weight by either limiting food intake, reducing nutrient absorption, or both. These surgeries are considered when:

  • A person has a Body Mass Index (BMI) of 35 or higher
  • A person has a BMI over 30 and is living with obesity-related health conditions (e.g. type 2 diabetes, sleep apnoea) are typically considered
  • Previous weight loss attempts through non-surgical methods have been unsuccessful
  • Obesity is negatively impacting health, mobility, or quality of life

In Brisbane, access to skilled surgeons, modern hospitals, and multidisciplinary teams makes bariatric surgery a viable option for many seeking obesity treatment Brisbane solutions. The key is understanding your options and partnering with a supportive provider like BGOS.

Surgical and Non-Surgical Obesity Surgery Options in Brisbane

BGOS offers a comprehensive range of weight loss surgery Brisbane procedures and non-surgical alternatives. Each option is carefully selected based on the patient’s goals, health history, and clinical needs.

Gastric Sleeve Surgery

The gastric sleeve (sleeve gastrectomy) is currently the most commonly performed weight loss surgery in Australia.

This procedure involves removing approximately 75% of the stomach, leaving a narrow tube or “sleeve”. It works primarily by restricting the amount of food you can eat and decreasing levels of the hunger hormone ghrelin.

Benefits:

  • Substantial weight loss (typically 50–70% of excess body weight)
  • Reduced appetite and improved satiety
  • Improvements in blood pressure, blood sugar, and cholesterol
  • Less complex anatomically compared to bypass

This is a popular choice for Brisbane patients seeking significant weight loss with fewer anatomical changes to the digestive system.

Gastric Bypass Surgery

Gastric bypass works through a combination of restriction and malabsorption. BGOS offers two types:

  • Roux-en-Y Gastric Bypass: A small stomach pouch is created and connected to the small intestine, bypassing a section of the digestive tract.
  • Mini Gastric Bypass: A simpler variation with one intestinal connection, offering similar results.

Ideal for patients with:

  • Type 2 diabetes
  • Severe reflux
  • High BMI with multiple health risks

Expected results: 60–80% excess weight loss, along with potential remission of diabetes and sleep apnoea, results may vary. 

Gastric Balloon Procedures

Not everyone is ready or eligible for surgery. BGOS provides several non-surgical options, including gastric balloons. These are temporary devices placed in the stomach to create a feeling of fullness and encourage portion control.

We offer:

  • Allurion Balloon: A swallowable capsule balloon that requires no surgery or anaesthesia. It naturally deflates and passes after ~16 weeks.
  • Orbera Balloon: Inserted via endoscopy and removed after 6 months.
  • Spatz3 Balloon: Adjustable and remains in the stomach for up to 12 months.

Benefits:

  • No permanent anatomical changes
  • Shorter recovery time
  • Can support initial weight loss or prepare for surgery

Revision Surgeries

If a previous bariatric procedure has not delivered expected results, revision surgery may be appropriate. BGOS specialises in complex revision procedures, including:

Our revision procedures are carefully planned and supported by our multidisciplinary team.

Benefits of Obesity Surgery: More Than Just Weight Loss

Bariatric surgery is not just about aesthetics or short-term weight reduction. It can deliver wide-ranging improvements in both physical and psychological wellbeing.

1. Long-Term Weight Loss

Patients often achieve 50–80% excess weight loss, depending on the procedure. More importantly, with continued lifestyle support, many maintain that loss for years. Results may vary. 

2. Diabetes Management and Remission

Many patients with type 2 diabetes experience improved blood sugar control or even remission following gastric bypass or sleeve procedures.

3. Better Cardiovascular Health

Bariatric surgery can reduce risk factors for heart disease by lowering blood pressure, improving cholesterol, and reducing inflammation.

4. Enhanced Mobility and Reduced Joint Pain

Carrying less weight eases pressure on joints, making daily movement easier and reducing pain in the knees, hips, and back.

5. Improved Mental Health

Weight loss and lifestyle changes often result in improved mood, increased self-confidence, and reduced symptoms of depression and anxiety.

6. Better Sleep

Many patients with sleep apnoea find they no longer need CPAP therapy after surgery, as weight loss helps open the airway.
