Achievements & Roles
Procedure Information
Roux-en-Y Gastric Bypass (RYGB)▼
A well-established weight loss surgery that reduces the size of the stomach and reroutes the small intestine to limit calorie and nutrient absorption. Promotes significant, sustained weight loss and improves or resolves conditions such as type 2 diabetes, high blood pressure, and gastroesophageal reflux disease (GERD).
One Anastomosis Gastric Bypass (OAGB)▼
Also known as Omega Loop Gastric Bypass, a simplified variation of the traditional gastric bypass. A small stomach pouch is created, and the small intestine is rerouted with a single connection. Shorter procedure time and fewer complications compared to traditional gastric bypass.
Sleeve Gastrectomyaround 70% of excess body weight▼
A minimally invasive weight loss surgery that removes about 70-80% of the stomach, creating a smaller, sleeve-shaped stomach. By reducing stomach size, patients can eat smaller portions and feel full faster. The removal of part of the stomach also decreases the production of hunger hormones, leading to reduced appetite and significant weight loss.
