Achievements & Roles
Procedure Information
Spatz 3 Adjustable Balloon (Gastric Balloon)▼
A non-surgical procedure that involves a temporary balloon being placed into the stomach to reduce its capacity. It is hoped this will reduce appetite and portion sizes, and is typically removed after 12 months.
Gastric Sleeve Surgery (Sleeve Gastrectomy)50-70% of excess body weight within 1-2 years▼
One of the most frequently performed weight loss procedures in Australia, this surgery reduces the stomach to a smaller, tubular shape (up to 90% may be removed). Approximately 70-80% of the stomach is removed, leaving a smaller, tube-shaped stomach (sleeve) that restricts food intake and reduces hunger by altering hormone production. Typically takes 1-2 hours.
Gastric Bypass Surgery (Roux-en-Y Gastric Bypass, or RYGB)▼
This procedure reduces stomach size by creating a small stomach pouch and reroutes part of the small intestine in a "Y" shape to limit food intake and calorie absorption (both through physical changes and altered hormones).
One Anastomosis Gastric Bypass (OAGB or Mini Gastric Bypass Surgery)60-80% excess weight loss within 1-2 years▼
Similar to a traditional bypass, this simplified procedure creates a long, narrow stomach pouch that is connected to the middle of the small intestine. It offers a shorter operating time and potentially fewer complications. Involves creating a small, tubular stomach pouch (approximately 30-50 mL) by dividing the stomach, with the small intestine connected in a single anastomosis. Typically takes 1-2 hours.
