Understanding your treatment options

There is no single procedure for everyone

Each bariatric procedure supports weight loss differently. The right option depends on your health, BMI, weight, medical history and long-term needs.

Your surgeon will explain the benefits and considerations of each procedure before recommending an option.

Procedures at a glance

Laparoscopic Sleeve Gastrectomy / Vertical Sleeve Gastrectomy

During sleeve gastrectomy, around three quarters of the stomach is removed, leaving a narrow, sleeve-shaped stomach through which food passes. This smaller stomach holds less food and removes much of the fundus, which produces the hunger hormone ghrelin. As a result, patients may feel less hungry, become full sooner and consume fewer calories. The intestines are not bypassed.

Laparoscopic Roux En Y Gastric Bypass

Roux-en-Y gastric bypass is one of the longest-established bariatric procedures. A small stomach pouch is created and connected to a lower section of the small intestine, allowing food to bypass the remaining stomach and part of the intestine. This limits food intake, changes digestion and affects the hormones involved in hunger, fullness and blood-sugar control.

Laparoscopic Mini-Gastric Bypass / Single Anastamotic Gastric Bypass

Mini gastric bypass, also called single-anastomosis or one-anastomosis gastric bypass, creates a long, narrow stomach pouch while leaving the remaining stomach in place. The pouch is connected to the small intestine using one surgical connection. This combines reduced food intake with changes in digestion and nutrient absorption, supporting weight loss and improvement in obesity-related conditions.

SADJ-S - (Single Anastomosis Duodeno-Jejunal Bypass with Sleeve Gastrectomy)

SADJ-S combines a sleeve gastrectomy with a single intestinal bypass. The stomach is reshaped into a narrow sleeve, and the duodenum is connected to a section further along the small intestine. This reduces stomach capacity while changing the route taken by food, creating restrictive, hormonal and metabolic effects that can support substantial weight loss and improvement in conditions such as type 2 diabetes.
