What is Sleeve Gastrectomy?
Sleeve gastrectomy, often referred to as the gastric sleeve, is a common form of metabolic and bariatric surgery used to assist patients with weight management when clinically indicated. During this procedure, a significant portion of the stomach is removed, leaving behind a sleeve-shaped section approximately the size and shape of a banana.
This smaller stomach restricts food intake, helping individuals reduce portion sizes and overall calorie consumption. Additionally, the procedure removes the part of the stomach that produces ghrelin—a hormone associated with appetite stimulation—potentially reducing feelings of hunger.

Procedure & Hospital Information
At Brisbane Obesity Clinic, we offer sleeve gastrectomy to appropriately assessed patients based on clinical need and in accordance with evidence-based guidelines.
Some medically recognised benefits of this procedure include:
- Improved Obesity-Related Conditions: May contribute to improvement or resolution of conditions such as type 2 diabetes, sleep apnoea, and hypertension.
- Weight Reduction Support: Research indicates patients may lose approximately 60–70% of their excess weight within the first 2–3 years post-surgery when combined with dietary and lifestyle changes.
- Minimally Invasive Approach: Typically performed laparoscopically, leading to smaller incisions, less discomfort, and shorter recovery.
- No Need for Band Adjustments: Unlike gastric banding, sleeve gastrectomy does not require adjustments or port fills.
- Enhanced Appetite Regulation: Reduced stomach capacity and lower ghrelin levels may help patients feel full with smaller portions.
Sleeve Gastrectomy may be considered for individuals with:
- A Body Mass Index (BMI) of 35 or higher, with or without obesity-related health conditions.
- A BMI between 30 and 34.9, depending on individual health factors and the outcome of a comprehensive clinical assessment.
All patients undergo a thorough assessment to determine whether surgery may be an appropriate treatment option. Recommendations are based on individual circumstances, medical history, overall health, and a careful consideration of the potential benefits and risks.
Suitability for surgery can only be determined following a personalised consultation and clinical evaluation.
- Hospital Stay: Typically one night.
- Recovery Time: Light activities within 2 weeks.

Common Questions (FAQs)

How long is the recovery period after surgery?
Most patients take around 2 weeks to recover. At their two-week post-op checkup, many patients report feeling fantastic!
What are the post-operative restrictions?
- No lifting for 2 weeks
- No driving for at least 1 week
- No cardio or swimming for 3 weeks
- Light weights (up to 5kg) allowed after 4–6 weeks
- No heavy lifting for 6 weeks
- No smoking
Do I need to see a dietitian before surgery?
Yes, all patients are required to see a dietitian before weight loss surgery. Your dietitian will help you follow a special pre-operative diet, which is important for reducing the size of your liver and making the surgery safer. It also helps with initial weight loss, improves your overall health, and prepares you for the dietary changes you’ll need to follow after the procedure. Seeing a dietitian before surgery is a key part of ensuring the best possible outcome.
Do I need to see a dietitian after surgery?
All bariatric patients will see our dietitians after their procedure to guide them through the different dietary phases.
We schedule regular appointments with our dietitians for up to 12 months after surgery. There is no charge for any post-operation appointments during this time. After the 12-month period, we recommend that you continue your long-term care with your GP or a private dietitian.
Do I require to see a psychologist prior to having this procedure?
While a psychological assessment is not mandatory before surgery, patients who wish to speak with a psychologist are welcome to do so. We are happy to provide a referral upon request to support your wellbeing throughout your weight loss journey.
Will I need to take vitamin supplements?
Yes. Depending on your procedure, you’ll likely need to take supplements (e.g., vitamin B12, folic acid, iron) for at least a year. Our dietitian will assess your needs during checkups. Multivitamins are available for purchase at reception.
Will I be able to take my regular medications after surgery?
Yes. You may need to adjust how you take them (e.g., using capsules, splitting larger tablets, or dissolving them). Always consult your prescribing doctor.
How much weight can I expect to lose?
Weight loss results vary from patient to patient, and the amount of weight you may lose depends on several things. A weight loss of around a kilo a week in the first year after the operation is possible, but half a kilo per week is more likely. Twelve to eighteen months after the operation your weekly weight loss is often less.
Remember that you should lose weight gradually. Losing weight too fast creates a health risk and can lead to a number of problems. Your main goal is to have weight loss that prevents, improves, or resolves the health problems associated with severe obesity. You need to be committed to your new lifestyle and eating habits. It is very important to set achievable weight loss goals from the beginning. Obesity surgery is not a miracle cure, and the kilograms won't come off by themselves.
Can I eat anything after surgery?
Eventually, yes—but in small portions. Focus on nutrient-rich foods. Avoid high-sugar, high-fat foods or drinks with empty calories (e.g., milkshakes), which can hinder results.
What about alcohol?
Avoid alcohol for at least 14 days post-surgery. After that, occasional consumption is okay. Keep in mind alcohol is high in calories and breaks down vitamins.
Will I suffer from constipation?
Some reduction in stool volume is normal due to lower food intake. If you experience any problems, let us know right away.
Is the Sleeve Gastrectomy reversible?
No. This is a permanent surgical procedure.
Can I fall pregnant after the procedure?
Yes, but it’s recommended to wait 12 months before trying to conceive. Many patients experience improved fertility after weight loss.
I have sleep apnoea—will surgery help?
Yes! Many patients report significant improvement or resolution of sleep issues post-surgery. Keep your sleep specialist informed.
Will I need plastic surgery for loose skin?
Possibly. This depends on a range of individual factors, including the amount of weight lost and your skin's natural elasticity.
In some cases, body contouring procedures such as abdominoplasty (tummy tuck) may be considered after significant weight loss. These procedures are generally discussed once your weight has stabilised, which is often 1–2 years after treatment.
A comprehensive assessment is required to determine whether any additional procedures may be appropriate for your individual circumstances.
