Are you living in Brisbane and ready to take the next step in your weight loss journey? If you’ve struggled to lose weight through diet, exercise, or medication, gastric sleeve surgery could be a life-changing solution. At Brisbane General & Obesity Surgery, our highly experienced team offers tailored support for individuals considering this proven bariatric procedure. A consultation is your first opportunity to explore your options with confidence and clarity.

What Is Gastric Sleeve Surgery?

Gastric sleeve surgery, medically known as sleeve gastrectomy, is a safe and effective bariatric procedure that reduces a significant portion of the stomach. The remaining stomach takes on a narrow, tubular shape—about the size and shape of a banana.

This permanent surgical change limits how much food you can eat at one time and significantly reduces your appetite by decreasing the production of ghrelin, the hormone responsible for hunger. As a result, most patients experience sustained weight loss and better control over eating behaviours.

The procedure is performed laparoscopically (keyhole surgery), meaning it involves small incisions, less post-operative discomfort, and a shorter hospital stay.

Who Is Gastric Sleeve Surgery Suitable For?

Gastric sleeve surgery is not a one-size-fits-all solution. However, it is typically recommended for individuals who meet the following criteria:

  • BMI of 40 or higher, regardless of other health conditions
  • BMI between 35 and 39.9, with obesity-related conditions such as:

    • Type 2 diabetes
    • High blood pressure
    • Sleep apnoea
    • Fatty liver disease
    • Joint pain or limited mobility
  • Have made sustained efforts to lose weight through medically supervised diets, exercise, and lifestyle programs without long-term success when combined with long-term lifestyle changes.
  • Are mentally and emotionally prepared for permanent lifestyle changes
  • Are non-smokers or willing to quit prior to surgery

Our team will confirm your eligibility and readiness through a detailed consultation process. Learn more about our approach on the FAQs page.

Benefits of Sleeve Gastrectomy

Choosing gastric sleeve surgery offers a range of medical and quality-of-life benefits. These include:

1. Long-Term Weight Loss

Most patients lose between 60% and 70% of their excess body weight within the first 12–18 months. With commitment to healthy lifestyle changes, weight loss is sustainable over the long term.

2. Improved Health Outcomes

Gastric sleeve surgery can significantly improve or even resolve obesity-related conditions such as:

  • Type 2 diabetes
  • Hypertension
  • High cholesterol
  • Gastroesophageal reflux disease (GERD)
  • Non-alcoholic fatty liver disease (NAFLD)
  • Polycystic ovarian syndrome (PCOS)

3. Reduced Hunger and Cravings

Hormonal changes following sleeve gastrectomy help reduce the sensation of hunger, making it easier to stick to your nutritional plan and avoid overeating.

4. Enhanced Quality of Life

Many patients report increased energy, improved mobility, greater confidence, and enhanced mental health following surgery. The ability to engage in physical activity and social situations more comfortably can also significantly boost overall wellbeing. 

5. Minimally Invasive with Short Recovery

Because the procedure is usually performed laparoscopically, it results in less post-operative pain, reduced scarring, and a faster return to normal daily activities.

What to Expect During Your First Consultation

A gastric sleeve consultation at Brisbane General & Obesity Surgery is more than an introduction—it’s the foundation of your tailored weight loss journey. During your consultation, our team will guide you through several key components:

1. Assessment of BMI and Medical History

We begin by calculating your BMI and thoroughly reviewing your health history. This includes identifying any obesity-related conditions and past surgical procedures. Understanding your full medical picture allows us to assess the safety and suitability of surgery.

2. Lifestyle and Psychological Evaluation

We’ll explore your day-to-day habits, emotional relationship with food, activity levels, and past weight loss attempts. This helps us design an approach that is realistic and sustainable.

Where appropriate, a psychological screening will ensure you are mentally prepared for the challenges and changes that come after surgery. Our priority is to set you up for success—both physically and emotionally.

3. Setting Expectations and Confirming Eligibility

We’ll discuss your motivations, goals, and what you hope to achieve. Our team will help you understand what life will look like after surgery, including dietary adjustments and long-term follow-up.

If sleeve gastrectomy is appropriate, we will explain the next steps clearly. If not, we may suggest other options from our range of bariatric surgeries that align with your individual profile.

Pre-Surgery Preparation

Preparing for gastric sleeve surgery involves careful planning to ensure the best outcomes. Here’s what’s typically included:

  • Nutritional Guidance: A dietitian will help you transition to a pre-surgical diet, typically low in carbohydrates and designed to shrink the liver and reduce surgical risk.
  • Medical Testing: You may require blood tests, ECG, sleep studies, or imaging to ensure you are fit for surgery.
  • Psychological Support: If you have a history of emotional eating or psychological conditions, we may recommend counselling or support services to help you prepare.

This multidisciplinary support ensures that you’re physically and emotionally ready for surgery and sets the stage for long-term success.

Aftercare and Long-Term Recovery Support

Surgery is just one part of the journey. At Brisbane General & Obesity Surgery, we prioritise structured aftercare to help you transition into a healthier, more active lifestyle.

What Recovery Looks Like:

  • Hospital Stay: Most patients will have a short hospital stay and are up and walking within hours of surgery.
  • Post-Surgery Diet: You’ll progress from clear fluids to puréed foods, then soft and finally solid foods over 4–6 weeks but note that results may vary per patient.
  • Activity: Gentle movement is encouraged within days, with most patients returning to work and light duties within 2–4 weeks but note that results may vary per patient. 
  • Wound Care and Follow-Ups: Our team will guide you in caring for incisions and schedule regular follow-up appointments.

Ongoing Support:

  • Dietitian Consultations: Regular appointments to monitor your intake and nutrition
  • Psychological Support: Referrals and resources for maintaining mental health
  • Support Groups: Access to patient communities for shared experiences and encouragement
  • Monitoring Health Markers: Regular checks on weight, blood pressure, blood sugar, and other relevant metrics 

Our goal is to provide the education, tools, and encouragement you need to maintain weight loss and adopt a healthier lifestyle for life.
