Available Weight Loss Surgery Procedures

Several types of bariatric surgery procedures are available to help patients achieve significant and sustained weight loss. Each procedure works in a slightly different way and may be recommended depending on a patient’s BMI, medical history and weight loss goals.

At BodyFree, our bariatric surgeon (Dr David Joseph) performs a range of modern weight loss procedures designed to support long-term health and weight management.

Gastric Sleeve, Laparoscopic Sleeve Gastrectomy

Gastric Sleeve Surgery

Gastric Sleeve Surgery (Sleeve Gastrectomy) is one of the most commonly performed bariatric procedures worldwide. The surgery removes around 75–80% of the stomach, creating a smaller sleeve-shaped stomach that limits food intake and reduces hunger hormones.

This procedure provides effective long-term weight loss and metabolic improvement for many patients.
Learn more about Gastric Sleeve Surgery.
Mini Gastric Bypass, Single Loop Gastric Bypass

Single Loop Gastric Bypass

Single Loop Gastric Bypass (also known as Mini Gastric Bypass or Omega Loop Gastric Bypass) combines stomach restriction with a bypass of part of the small intestine, helping reduce calorie absorption while limiting food intake.

This procedure may be recommended for patients who require greater weight loss or improved metabolic outcomes.

SADI-S Bariatric Surgery

SADI-S Surgery

SADI-S (Single Anastomosis Duodeno-Ileal Bypass with Sleeve) is a more complex bariatric procedure that combines a sleeve gastrectomy with intestinal bypass to achieve powerful metabolic effects.

It may be recommended for patients with severe obesity or metabolic disease.

Revision Bariatric Surgery

Revision Bariatric Surgery

Revision Bariatric Surgery may be recommended for patients who have previously undergone weight loss surgery but have experienced weight regain, complications or insufficient weight loss.

Revision procedures may convert one bariatric procedure to another to improve long-term outcomes.

Mini Gastric Bypass, Single Loop Gastric Bypass

Roux-en-Y Gastric Bypass

Roux-en-Y Gastric Bypass is a well-established bariatric procedure that creates a small stomach pouch and reroutes part of the small intestine.

This changes how food is digested and absorbed, helping support significant weight loss and improvements in obesity-related health conditions.

What Weight Loss Surgery Procedure Is Right For Me?

Deciding which surgery option would be best for you will require consultation with one of our expert Bariatric Surgeon, Dr David Joseph. There are many factors that will be considered when recommending which of the weight loss surgery procedures is best for you.

The surgeon will look at BMI (body mass index) as a first step, and then also consider health concerns or diagnosed co-morbidities such as diabetes, heart disease, sleep apnoea, cholesterol issues, joint pain, reflux issues (GORD) and for female patients – Polycystic Ovarian Syndrome (PCOS). Each patient who comes to see us is treated as an individual with recommendations always based on that individual patient’s needs.

Depending on which surgical procedure is recommended, Weight Loss Surgery works by either restriction of food intake (Gastric Sleeve) or a combination of restriction and malabsorption of nutrients (Single Loop Gastric Bypass, Roux-en-Y Gastric Bypass, SADI). Your surgeon will provide further information about this during your consult, or you can find more details by clicking on the procedures below to be directed to more information.

Common Questions

Weight Loss Surgery Procedure FAQs

Our clinic does not offer endoscopic weight loss surgery procedures, such as the Gastric Balloon, however we have included some general information about these options. Endoscopic procedures generally offer short term weight loss outcomes without any medium to long term results shown.

While we do offer a surgical procedure to remove Gastric Bands (Lap Bands), with or without revising to a Gastric Sleeve or Gastric Bypass, we do not provide surgery to place them into the body.

Our bariatric surgeons have found that patients who have had a Gastric Band placed encounter more post operative concerns and problems and also have inconsistent results when compared to the newer weight loss surgery procedures (Gastric Sleeve, Gastric Bypass).

Through Bariatric Surgery, our team have had the opportunity to see our patients improve their lives using the tools that weight loss surgery procedures provide.

Following surgery patients are able to address their weight and health concerns and finally feel free of the kilos they feel have held them back from living the life they always wanted.

Real Patient Experiences

Bariatric Surgeon Dr David Joseph and the BodyFree team has helped more than 7,000 weight loss surgery patients achieve their health and weight goals.

I had a mini bypass in September 2024 and it was one of the best decisions I ever made. Right from the initial consult to now, 18 months post-surgery, I have been well-supported by the surgeon, dietician, and other staff at BodyFree Weight Loss Clinic. They have done fabulous post-care, keeping track of how I am going and how I might need to make lifestyle or diet adjustments. I would encourage anyone who is sitting on the fence to give BodyFree Weight Loss Clinic very serious consideration if you make a decision to go for it. I have been very happy!

I can’t thank the whole team enough, from initial consultation all the way to the operating table the process was simply and the work done was amazing. Both pre and post surgery I found amazing! Thank you Dr Joseph and all the team involved for giving me the extra push and helping me get my life back.

Recently I utilised the services of BodyFree and have to say it has been the best experience. My Surgeon was Dr Joseph, a no nonsense, tell you how it is Doctor. I knew what to expect at every part of the journey and although my interactions with him were very short and sweet, he showed empathy and you could tell he genuinely cared that my experience was a good one and all questions had been answered. All in all, if I could rate my experience higher than a 5, I would.

Thanks to Dr. Joseph, Natasha Leader, Bianca and Heather, and everyone at the BodyFree Clinic. I wholeheartedly recommend Dr. David Joseph to anyone considering gastric sleeve surgery. He is not just a highly skilled surgeon but also a compassionate professional who, along with his dedicated team, truly changes lives for the better.

I first came to see Dr Joseph on the recommendation from a good friend. The care, support & professionalism from Dr Joseph, Heather & Bianca has been, and continues to be nothing short of incredible. Along with additional help from Natasha Leader as my dietician, my goals have been achievable. Nothing has ever been too much trouble for David or his team - they've been genuinely interested in my progress and the aftercare is impeccable. If I could give more than 5 stars, I wouldn't hesitate.
