Who is eligible for weight loss surgery in Australia?

Surgery is generally recommended for adults with a BMI of 40+, or BMI 35+ with a significant obesity-related condition such as type 2 diabetes or hypertension. A comprehensive assessment with Dr Keeley will determine your suitability.

How much weight will I lose after gastric sleeve?

Most patients lose 60–70% of their excess body weight within 12–18 months of gastric sleeve surgery. Results vary depending on adherence to dietary and lifestyle changes.

Is Medicare available for bariatric surgery?

Yes. Medicare rebates apply to gastric sleeve and gastric bypass surgery when performed by a qualified bariatric surgeon like Dr Florica FRACS. Private health insurance may cover hospital fees.

Gastric Sleeve Surgery (Sleeve Gastrectomy)

Sleeve gastrectomy removes approximately 75–80% of the stomach to create a slim, sleeve-shaped pouch — restricting food intake and significantly reducing the hunger hormone ghrelin.

It is the most commonly performed bariatric procedure worldwide, with an excellent safety profile and outstanding long-term weight loss outcomes.

Weight loss
60–70% of excess weight

Hospital stay
2–3 days

Procedure time
60–90 minutes

Return to work
2–3 weeks

✓Significantly reduces hunger hormone (ghrelin)
✓No rerouting of the intestine
✓Simpler than gastric bypass
✓Medicare rebates available
✓Can be converted to bypass if needed

1

General Anaesthetic

You are fully asleep throughout the procedure.

2

Laparoscopic Access

Small incisions allow insertion of a camera and surgical instruments.

3

Stomach Resection

75–80% of the stomach is removed, leaving a narrow sleeve-shaped pouch.

4

Recovery

2–3 nights in hospital, then a structured recovery and dietary program.

Gold Standard for Diabetes

Gastric Bypass Surgery (Roux-en-Y)

1

Create a Small Pouch

The upper stomach is stapled to create a ~30ml pouch.

2

Reroute the Intestine

The small intestine is divided and attached directly to the new pouch.

3

Dual Mechanism

Both restriction and reduced absorption combine for powerful weight loss.

4

Hospital Recovery

3–4 nights in hospital with structured post-operative support.

Gastric bypass (Roux-en-Y) is considered the gold-standard metabolic procedure, offering the greatest weight loss and the highest rates of type 2 diabetes remission of any bariatric surgery.

It is the preferred choice for patients with severe reflux (GORD), type 2 diabetes, or those requiring maximum weight loss outcomes.

Weight loss
70–80% of excess weight

Hospital stay
3–4 days

Diabetes remission
Up to 80%

Return to work
3–4 weeks

✓Highest weight loss outcomes

Revisional Bariatric Surgery

If a previous bariatric procedure (such as a gastric band or sleeve) has not produced adequate results or has led to complications, Dr Florica offers revision surgery — including conversion from sleeve to bypass and correction of complications from prior operations.

Hiatal Hernia Repair

A hiatal hernia — where the upper stomach protrudes through the diaphragm — is common in patients with obesity and can cause severe reflux. Dr Florica routinely performs laparoscopic hiatal hernia repair, often in combination with bariatric procedures such as gastric bypass.

Anti-Reflux Surgery

For patients with chronic gastro-oesophageal reflux disease (GORD) not controlled by medication, laparoscopic anti-reflux surgery (Nissen fundoplication or similar) offers a long-term solution — often performed alongside or instead of a bariatric procedure.
