What Happens During One Anastomosis Gastric Bypass

Here’s how a typical patient journey looks like, once you’ve reached out.

01

Thoughtful Pre-Surgery Evaluation

Comprehensive health assessment, diabetes/hormone evaluation, nutrition counseling, and preparation

02

Minimally Invasive Surgery

Performed laparoscopically through small incisions for quicker recovery and minimal scarring

03

Stomach is Reduced

A narrow tube-shaped stomach pouch is created, reducing the amount of food intake.

04

Single Anastomosis

The intestine is attached to the pouch at a single connection, simpler than Roux-en-Y and effective in reducing calorie absorption

05

Powerful Metabolic Benefits

Reduces hunger, improves insulin sensitivity, and enhances metabolic function
