Gastric bypass

Gastric bypass procedures create a smaller stomach pouch and change the pathway through which food travels through the gastrointestinal tract.

These procedures result in changes to appetite regulation, satiety, gut hormones, glucose metabolism and nutrient absorption, contributing to substantial weight loss and improvements in metabolic health.

Two commonly performed gastric bypass procedures are the Roux-en-Y gastric bypass and the one anastomosis gastric bypass.

The procedures differ in their surgical technique, potential benefits, risks and long-term nutritional considerations.

Gastric bypass may be particularly appropriate for some people depending on their medical conditions, previous treatments, eating behaviours and individual health needs.

Careful procedure selection and lifelong nutritional and medical monitoring are essential.
