Understand the procedure

What is Gastric Bypass (Roux-en-Y)?

Roux-en-Y gastric bypass creates a small upper stomach pouch and connects it to a lower segment of small intestine. It limits meal size and changes nutrient flow, gut hormones and blood-sugar regulation.

Roux-en-Y gastric bypass combines restriction with metabolic and absorptive effects. The choice requires detailed assessment of reflux, diabetes, medication use and nutritional risk.

Individual selection

Who may be considered?

BMI alone does not select a treatment. Medical history, metabolic health, reflux, previous procedures, nutrition and capacity for long-term follow-up are considered together.

Severe obesity requiring a durable surgical option

Type 2 diabetes or significant metabolic disease

Clinically important reflux where sleeve may be less suitable

Selected revision after a previous bariatric procedure

Clinical safety:

This is general information. A decision should follow discussion of individual risks, alternatives and the option of no procedure.

A first screening step

Calculate BMI—then decide with the team.

BMI is only one part of assessment. Procedure choice also depends on medical history, related conditions, anatomy, nutrition and individual risks.

Your result—

Enter your height and weight for a screening BMI estimate.

BMI is a screening measure, not a diagnosis or a decision about surgery. Medical history, related conditions, nutrition, previous weight-management attempts and surgeon assessment are also required.
