What Is Weight Loss Surgery?
Weight loss surgery, also known as obesity or bariatric surgery, is a medical intervention aimed at supporting weight loss in individuals with severe obesity when diet and exercise have not provided long-term results. This is typically done by reducing stomach capacity and altering digestion to reduce calorie intake or absorption.
Obesity surgery includes a variety of procedures, including the Spatz3 adjustable balloon, sleeve gastrectomy, and gastric bypass.
Undergoing surgery may also help improve obesity-related conditions, such as type 2 diabetes or hypertension, though outcomes depend on individual factors.
To find out if you’re eligible for surgery and which procedure is best for you, a thorough medical and psychological evaluation with a bariatric surgeon is required.
Who Is Bariatric Surgery For?
Weight loss surgery may be an option for:
- Individuals with a body mass index (BMI) above 35, or over 30 with an obesity-related health condition.
- Those dealing with obesity-related health conditions, such as type 2 diabetes, hypertension, sleep apnoea, chronic joint pain, or infertility.
- People for whom non-surgical weight loss methods have not produced results.
In your initial consultation, we will review your health and lifestyle goals to identify the most suitable option for you.
Types of Obesity Surgery
Weight Loss Treatment Options
Northern Surgical Care currently offers the following weight loss procedures:
Spatz 3 Adjustable Balloon (Gastric Balloon)
This non-surgical treatment involves placing a temporary balloon in the stomach to decrease its capacity, helping to reduce appetite and portion sizes. It is usually removed after 12 months.
Gastric Sleeve Surgery (Sleeve Gastrectomy)
A commonly performed weight loss surgery in Australia, this procedure reduces the stomach to a smaller, tubular shape, removing up to 90%. It is designed to limit food intake, helping you feel full quicker.
RYGB Gastric Bypass Surgery (Roux-en-Y Gastric Bypass)
This procedure reduces stomach size by creating a small pouch and rerouting part of the small intestine in a “Y” shape to limit food intake and calorie absorption, through both physical changes and hormonal alterations.
One Anastomosis Gastric Bypass (OAGB or Mini Gastric Bypass Surgery)
Like a traditional bypass, this simplified procedure creates a long, narrow stomach pouch that connects to the middle of the small intestine, providing a quicker operation and potentially fewer complications.
In your initial consultations, the benefits and risks of each procedure, including possible surgical complications and nutritional deficiencies, will be explained thoroughly to ensure informed decision-making.
What to Expect
The Bariatric Surgery Experience
We will review your medical history, weight history, and overall health goals during your consultation. Diagnostic tests like bloodwork or an endoscopy may also be suggested to determine your suitability for surgery.
If a procedure is deemed appropriate, we will provide you with a detailed plan outlining preparation for bariatric surgery, the procedure itself, and the recovery process.
Our partners at Liora Health provide comprehensive aftercare, including nutrition, nursing, and psychological support, to help you throughout your health journey.
Frequently Asked Questions
What Are The Risks Of Weight Loss Surgery?
All surgical procedures carry inherent risks, but bariatric surgery is widely performed and backed by extensive clinical research. Dr Gunawardene prioritises careful patient selection, risk minimisation, and evidence-based techniques to ensure patient safety.
How much weight will I lose?
Weight loss results differ based on the procedure, starting weight, and long-term lifestyle habits. Surgery helps with weight loss, but sustained success depends on ongoing support in diet, behaviour, and medical care.
What is the recovery time after surgery?
Recovery time depends on the procedure and individual factors. Many patients return to light activities within a few weeks, with a gradual return to normal activities. Full recovery guidelines will be given prior to your procedure.
