Roux-en-Y Gastric Bypass (RYGB) is a common weight loss surgery where a small pouch is created from the stomach and connected to the small intestine, bypassing a portion of the stomach and intestine. This reduces the amount of food the stomach can hold and limits nutrient absorption.

The surgery involves two main steps: creating the pouch and rerouting the small intestine. This procedure is highly effective for long-term weight loss and is often recommended for patients with severe obesity.

Postoperative care includes managing dietary changes, taking vitamin and mineral supplements to prevent nutritional deficiencies, and regular follow-ups to monitor weight loss and health improvements.

RYGB offers significant weight loss and health improvements for patients with severe obesity, and it can also lead to the resolution of comorbidities like type 2 diabetes, hypertension, and sleep apnea.
