Roux-en-Y Gastric Bypass

Q: Is Roux-en-Y Gastric Bypass reversible?

RYGB is technically reversible but rarely performed as reversal is complex. Changes are intended to be permanent.

Q: How quickly does blood sugar improve?

Blood glucose normalises within days to weeks, often before significant weight loss. Over 80% achieve HbA1c below 6.5% within 12 months.

Q: What vitamins must I take lifelong after gastric bypass?

Iron, vitamin B12, calcium, vitamin D, and folate supplementation is required lifelong. Regular 6-monthly blood tests guide adjustments.

Gold standard bariatric procedure — small gastric pouch with intestinal bypass for maximum weight loss and diabetes remission.

What is Roux-en-Y Gastric Bypass?

Roux-en-Y Gastric Bypass creates a small 30 ml gastric pouch connected to a rerouted segment of small intestine in a Y-configuration. This simultaneously restricts intake, reduces hunger hormones, and limits calorie absorption, producing the most consistent long-term weight loss and the highest Type 2 Diabetes remission of any bariatric procedure. Dr. Tagore Mohan Grandhi performs Roux-en-Y Gastric Bypass laparoscopically, drawing on fellowship training at Legacy Health System and the University of Kentucky, USA.

Suitable for patients with BMI 40+, or BMI 35+ with Type 2 Diabetes or obesity-related comorbidities — particularly where diabetes remission is a primary goal.

How the Procedure Works

Gastric Pouch Formation

Small 30 ml stomach pouch created from the upper stomach using a laparoscopic stapler, completely divided from the remnant stomach.

Roux Limb Creation

Small intestine divided 30–50 cm from the ligament of Treitz. Alimentary (Roux) limb measured to 100–150 cm.

Gastrojejunostomy

Alimentary limb connected to the gastric pouch by a stapled or hand-sewn gastrojejunostomy, bypassing the remnant stomach and duodenum.

Biliopancreatic Anastomosis

Biliopancreatic limb reconnected to the Roux limb downstream (jejunojejunostomy), completing the Y-configuration.

Leak Testing & Recovery

All anastomoses tested intraoperatively. Liquid diet from day one. Lifelong vitamin supplementation. 3-monthly metabolic review.
