Quick facts

• Procedure: Roux-en-Y gastric bypass (small pouch + intestinal reroute).
• Approach: Minimally invasive (keyhole) under general anaesthesia.
• Stay: Usually 2–3 nights in hospital.
• Return to desk work: ~1–2 weeks (varies).
• Support: Structured follow-up and dietitian guidance.

Who is a suitable candidate?

• BMI ≥ 35, or BMI ≥ 32 with weight-related conditions (e.g., type 2 diabetes, sleep apnoea).
• Previous attempts at weight loss with lifestyle measures.
• Troublesome reflux or significant diabetes may favour bypass over sleeve.
• Ready to commit to long-term nutrition, activity and follow-up.

Final suitability is determined during your consultation after a personalised risk–benefit discussion.

How the gastric bypass works

1. Anaesthesia & access: Small laparoscopic incisions under general anaesthesia.
2. Pouch creation: A small stomach pouch is formed at the top of the stomach.
3. Intestinal rerouting: The “Roux” limb is joined to the pouch, with the intestine reconnected further down.
4. Checks & closure: All joins are tested; incisions are closed with small dressings.

This reduces capacity and modestly reduces absorption. Hormone effects support fullness, reduce cravings and improve metabolic health.

Benefits you can expect

• Effective weight loss: Clinically significant reduction in excess body weight over 12–18 months.
• Metabolic improvements: Strong evidence for type 2 diabetes improvement/remission and reflux relief vs sleeve.
• No implanted device: No bands or ports.
• Keyhole recovery: Smaller scars and typically faster recovery.

Risks & considerations

All surgery carries risk. Potential risks include bleeding, infection, anastomotic leak, venous thrombosis, internal hernia or obstruction, marginal ulcers (higher with smoking/NSAIDs), dumping syndrome, strictures, and nutritional deficiencies requiring lifelong supplementation. Your surgeon will explain individualised risks, benefits and alternatives.

Recovery & aftercare

• Phase 1 (weeks 0–2): Fluids only; hydration and protein as advised.
• Phase 2 (weeks 2–4): Pureed textures; gradual volume increase.
• Phase 3 (week 4+): Soft → regular foods; protein first, mindful eating, daily movement.

Lifelong vitamins/minerals and scheduled blood tests are recommended.
