There is alot of mis-information online about the pros and cons of gastric sleeve vs bypass surgery.

There is good reason why gastric sleeve surgery remains the most common weight loss operations performed world wide.
Beyond just weight loss, each surgery needs to be individualised to patient needs depending on their eating habits, overall risk appetite and whether they have signficiant metabolic issues like uncontrolled diabetes.
One of the common mis-conceptions is that patients do not weight gain after bypass surgery... This is certainly not true. All bariatric operations need to be viewed as a power vehicle to help drive weight loss but ultimately relies on you doing the driving!

Dr Cheng aims to share his experience about about the gastric sleeve:
- the expected weight loss outcomes
- who is it for?
- why its still regarded as the best ALL ROUNDED weight loss tools especially for someone getting into weight loss surgery for the first time.

Comment below if you have any burning questions that you would like Dr Cheng to answer 👇👇👇

Great to be part of the robotic program at Kareena Private!
Our first Robotic surgical list at Kareena was completed seemlessly.

More than just the surgeon, each robotic case relies on strong collaboration and technical know-how from the entire team.

Strong start and full confidence in the hospital to deliver Top Level Robotic Surgery care within the Shire! 💪👏👏👏

Obesity can affect life in many ways.

Sometimes, the impact isn't visible.

It can be the stairs you stop taking.
The clothes you no longer feel comfortable wearing.
The photos you avoid.
The activities you slowly stop enjoying.
The tiredness that makes everyday life harder.
The confidence that gradually fades.
The inability to keep up with your love ones.

And it can affect health too — increasing the risk of metabolic conditions such as type 2 diabetes, heart disease, sleep apnoea and joint problems.

But a person is never defined by their weight.

Obesity is a complex chronic disease. It isn't simply about willpower, and every person's experience is different.

So perhaps the question isn't just:
“How much weight should I lose?” but rather "How is my weight affecting the life I want to live?"

Because treatment isn't just about changing a number on the scales.

It's about helping people live healthier, fuller lives. ❤️

Thats a wrap from IFSO Toronto 2026!

A timely meeting to help everyone align the future direction of obesity management.
There was alot of new clinical trial data on medical therapy being presented, highlighting both the pros and cons of GLP-1 therapies.

The messaging from this conference was clear - the way of the future is going to be integrated obesity care through multi-modality therapy in treating a chronic disease process. The available treatment options are expanding and we as clinicans need to embrace change and effectively guide our patients.

The yearly IFSO meeting is a great time to catch up with close friends and colleagues from across the world! Already looking forward to next year's IFSO asian pacific chapter in Singapore and IFSO world congress in Paris!

As IFSO 2026 comes to an end…

Let’s reflect on some of the key messages from this year’s world conference.

Here are 9 key messages highlighting results from some of the major clinical trials and ever changing landscape in obesity management.

in 2026, we have quite alot of options when it comes to weight loss management.

A question that needs answered is "whether gastric balloons can still cut it in 2026??"

Hear from Dr Cheng about his CANDID OPINION about gastric balloons and whether it is still worthwhile for you.

When it comes to weight loss outcomes, we are seeing GLP-1 medications match the results
achievable by Gastric balloons. Both have question marks over weight loss sustainability unless GLP-1 medications are used long term.

Gastric balloons remains a NICHE weight loss treatment tool in patients who have had sub-optimal outcomes with GLP-1, yet hesitant about undergo bariatric surgery. Is the balloon for everyone? Not quite but does remain an option in bridging the therapy gap between medication and surgery.

Weight loss management has become quite complex with multiple treatment pathways.
If you have been thinking about weight loss, chat with Dr. Cheng about what the best options for you.

For decades, BMI has been one of the main ways we define and measure obesity.

But we are starting to understand that our focus is flawed.

BMI doesn’t tell us:
• How much of that weight is fat vs muscle
• Where the fat is distributed
• How much intra-abdominal fat is present
• Whether we are preserving muscle during weight loss
• What our metabolic health looks like
• How obesity is affecting our function and quality of life

Two people can have the same BMI but very different body composition, health risks and treatment needs.

Recent evidence and IFSO guidelines are moving towards driving management according to clinical obesity which places more emphasis on obesity related metabolic disease (like diabetes, heart disease, high blood pressure, sleep apnoea) rather than a single BMI number.

As obesity management evolves, we also need to be much more obsessed with body composition which accounts for muscle, fat and fluid percentages.

We should move away from just asking:

“What is your BMI?”

And start asking:

“What is your body composition?”

BMI can be a starting point.
It shouldn’t be the whole story.

It’s time to look beyond the number.

Time absolutely flies!

Last year this time, we were in Chile Santiago for the IFSO 2025 Conference.

This year, Dr Cheng is heading to IFSO Toronto in September to join up with fellow metabolic colleagues from around the world.

The International Federation for Surgery of Obesity and Metabolic Disorders (IFSO) conference is arguably the biggest bariatric conferences held in different global cities each year. It brings together leading specialists from across the world where we gather to learn, share knowledge and discuss the current/ future management of obesity.

Stay tuned for what this year will bring!

What hernia surgery is now is vastly different to even a decade ago.
We now have so many different techniques on how to tackle abdominal wall hernias which often translates to better outcomes for our patients.
Advancements in robotic surgery has really revolutionised the hernia surgery field which allows us to tackle most hernias through a minimally invasive approach.
If you have been troubled by a hernia, come talk to Dr. Cheng about how he would recommend for it to be fixed.

Super honoured to have been invited along with Dr Georgia Rigas to the TICOM/ IOS combined Global Conference 2026 held in Chengdu, China!

It was a great opportunity to meet up with esteemed local and international experts in Metabolic surgery to discuss the future of our field. The IOS community is a closely knit community where we can all gather with friends and colleagues to share experiences, knowledge while fostering new collaborative research opportunities! Biggest thanks to and for bringing everyone together!

For all Australian bariatric colleagues including surgeons, physicians and allied health experts who wish to be part of the growing International obesity society (IOS) community, you could join our growing society through: https://www.ios.xin/ or get in contact with me directly.
