When is bariatric surgery justified?
Surgery is prescribed only when clear criteria are met
The role of body mass index (BMI)
BMI is the primary tool for judging obesity. The formula: body weight (kg) divided by height squared (m²). Surgery is typically justified at a BMI above 40, or above 35 if there are serious related conditions. At times surgery is also considered with lower figures — provided non-surgical treatment has failed.
Key factors
- The patient's body mass index (BMI)
- Overall health and any related chronic conditions
- No success with earlier tries to slim down by usual means
Why don't diets and exercise work for everyone?
Plenty of people diet and exercise for years, only for the body to resist: a slower metabolism, a bigger appetite and the weight coming back. When diet changes and medication clearly cannot fundamentally improve matters on their own, the only effective option left is bariatric surgery.

Bariatric surgery methods at City Medical Centre
Sleeve gastrectomy
During surgery the surgeon removes most of the stomach, turning it into a narrow tube. This greatly reduces portion size and lowers ghrelin, the hunger hormone, so the patient feels full much faster and eats less.
Effectiveness: this method is for a BMI of 35 to 45. Patients drop 60–70% of excess weight on average.
Specifics: durability is lower than with bypass operations. If the diet slips, especially with high-calorie drinks and liquid food, lost weight may come back.
Roux-en-Y gastric bypass
At the top of the stomach the surgeon makes a small 50–70 ml pouch, linking it directly to the small intestine. Intake of food is restricted and calorie absorption falls, since food passes through less of the gut.
Effectiveness: this operation is seen as the “gold standard” with a BMI above 45–50 and type 2 diabetes. Excess weight falls by up to 75–85%.
Specifics: the effect lasts longer than with other bariatric methods. Related diseases, including diabetes and hypertension, often reach remission. As digestive anatomy changes, supplements of vitamins and minerals are needed for life.
Mini gastric bypass (MGB)
An advanced version of the classic bypass. Differing from the standard method, it involves only one connection (anastomosis) from the small stomach to the small intestine. The simpler technique is gentler on patients and needs a shorter recovery period.
Effectiveness: comparable with the classic Roux-en-Y bypass: patients drop up to 75–80% of excess weight.
Specifics: a faster operation and shorter recovery. The procedure can be undone technically, but there is a bile reflux risk from the single anastomosis.
Single anastomosis duodeno-ileal bypass (SADI-S)
SADI-S is a modern combined technique that unites the benefits of sleeve gastrectomy and intestinal bypass. It is done in two stages: first the stomach is turned into a narrow tube, then the small intestine is rerouted so that most of it is excluded from active digestion.
Effectiveness: one of the strongest bariatric procedures, with 80–90% excess weight loss and a long-lasting result.
Specifics: with the ghrelin-producing zone removed, the smaller stomach reduces appetite; redirecting food past part of the intestine limits calorie uptake. Used for super obesity (BMI over 50), severe type 2 diabetes, or as a second stage when a sleeve was ineffective.

City Medical Centre bariatric surgery centre
— your path
to confidence and harmony
City Medical Centre takes a comprehensive approach to obesity. After the first examination, each patient gets a personal diagnostic program (lab and instrumental) to identify every disorder in the body.
A method matched to your goal
Our doctors select the surgical method for each patient individually. Before deciding, they assess your health, weight history and related conditions to suggest the most suitable surgical treatment.
Support that stays in touch
City Medical Centre's team stays with you once surgery is over. During the first year, specialists monitor your weight loss and test results and answer any questions on diet and recovery.
Fast recovery
City Medical Centre's bariatric operations are laparoscopic, so recovery is much shorter. On day one most patients are already up and moving, and within a week they return to normal life.
Full diagnostics on site
No shuttling between clinics. Your full work-up happens at our centre, from our own lab to ultrasound and gastroscopy. Preparation is quick, there are no queues, and it is all in one building.
Recovery after bariatric surgery
How recovery goes is largely individual, yet minimally invasive laparoscopic techniques keep the rehabilitation period to a minimum.
Duration
The patient is monitored at the clinic for 1 to 5 days, according to the extent of surgery and any related conditions.
Activity
Sitting up, standing and drinking are allowed in the first hours after surgery.
Wound care
Absorbable sutures are used; they dissolve on their own.
Work
A return to work is possible 7–14 days after surgery, based on how physical your job is.
Restrictions
No sauna, no bathhouse and no intense physical exercise for the first weeks.
Diet
The stomach adapts through a staged diet over 1–2 months, progressing from liquids to solids.
Pace
When they follow specialist advice, patients lose an average of 10% of excess weight each month.
Stabilization
Full results are reached in 1.5–2 years. By then, stable eating habits are in place that prevent the weight from coming back.
Important! Recovery is supervised by City Medical Centre specialists, who provide psychological and medical support at every stage of weight loss.

Frequently asked questions
about bariatric surgery at CMC
Bariatric vs plastic surgery: what's the difference?
Many people confuse them, but the goals are fundamentally different. Bariatric surgery is a medical way to treat obesity and related diseases. It changes how the digestive tract works, getting at the causes of excess weight and metabolism. Plastic surgery only reshapes the body's outer contours; it does not treat obesity or affect metabolism.
How soon can I return to work and normal life?
Will there be visible scars?
Our approach is modern laparoscopic technique: 4 small punctures of 5 to 15 mm. We use cosmetic sutures, so the marks turn almost invisible after healing.
What diet do I need to follow?
Your diet changes in stages: from liquid food to soft, then to solid. The focus is on protein and on limiting high-calorie, fatty food.
What types of bariatric surgery are there?
City Medical Centre performs four main types of bariatric surgery: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. Each method is chosen individually based on BMI, related conditions and the patient's goals.
Can I plan a pregnancy after surgery?
Pregnancy after bariatric surgery is possible, but doctors advise waiting at least 12–18 months. During this time the body stabilizes, weight reaches target values and nutritional status normalizes.
Do I need to take vitamins after surgery?
Yes, vitamins are essential after bariatric surgery. As digestive anatomy changes, the body absorbs certain nutrients less well, so regular vitamin and mineral supplements become a lasting part of the patient's life.
Can the weight come back?
Weight regain is possible after bariatric surgery but very unlikely provided you follow the doctor's advice. Eat properly, avoid high-calorie drinks and keep up regular follow-up with City Medical Centre specialists.

When bariatric surgery in Sydney makes sense
Weight that began in childhood, a family history of obesity, shortness of breath on stairs, avoiding photos — these are common reasons people in Sydney start thinking about surgery. A consultation is warranted not only by a high BMI but also by related conditions. The surgeon reviews your health and weight history and offers the most suitable of the four surgical methods.
During the operation the surgeon works laparoscopically, which keeps rehabilitation as short as possible. Right after, you are under round-the-clock care in a ward, with meals and nursing included. After discharge, most people in Sydney return to their normal routine within a week, following a diet plan and avoiding saunas and heavy exercise for the first weeks.
If you are comparing bariatric surgery options in Sydney, look beyond the operation itself. Here the package bundles the work-up in the centre's own lab, laparoscopic surgery, the stay with meals and nursing, a doctor on hand 24/7 and a year of follow-up. Apply for a free surgeon consultation to see how this applies to your case.
