Procedure Information
Sleeve Gastrectomy70–80% of excess body weight within 12 months, with some achieving up to 100% excess weight loss▼
Sleeve gastrectomy permanently reduces the size of the stomach by removing 70–80% of it, leaving a sleeve-shaped tube of about 125ml (½ cup) in volume, helping patients feel full sooner while naturally decreasing appetite hormones. The procedure is performed using laparoscopic (keyhole) surgery.
Single Anastomosis (Omega-Loop) Gastric Bypass75–85% excess weight loss over 12–18 months, with some patients achieving full excess weight loss▼
Single Anastomosis Gastric Bypass (also known as OAGB or Mini Bypass) is a modern variation of the traditional Roux-en-Y Gastric Bypass requiring only one bowel join (anastomosis), reducing operative risk while offering powerful metabolic and weight-loss effects. A small gastric pouch is created and 200 cm of small intestine is bypassed.
Roux-en-Y Gastric Bypass75–85% of excess weight over 12–18 months, with some achieving complete excess weight loss▼
RYGB is a bariatric surgery that reduces the stomach size and reroutes part of the small intestine to limit calorie absorption and reduce appetite. Often considered the "gold standard" for patients with severe obesity or specific conditions like chronic gastro-oesophageal reflux disease (GORD) and Barrett's oesophagus.
Gastric Band Removal & Conversionaround 60% excess weight loss at 12 months (for conversion to sleeve)▼
For patients where a gastric band is no longer effective due to weight regain, reflux, or food intolerance, the band is removed laparoscopically and patients may convert to a sleeve gastrectomy or bypass. Conversion to sleeve is typically performed 10–12 weeks after band removal.
