Roux-en-Y Gastric Bypass in Central London
Advanced weight-loss and metabolic surgery performed by leading consultant bariatric surgeons at LSDC Healthcare.
At LSDC Healthcare, we provide Roux-en-Y gastric bypass (RYGB) — the gold-standard bariatric operation for patients seeking significant, durable weight loss and powerful metabolic improvement.
Our consultant surgeons combine precision, safety, and evidence-based care within a multidisciplinary programme that includes endocrinology, dietetics, and psychology, ensuring every aspect of the patient journey is supported from preparation to lifelong follow-up.
What Is a Roux-en-Y Gastric Bypass?
This minimally invasive (laparoscopic) procedure involves:
-
Creating a small stomach pouch to limit food intake.
-
Connecting the pouch to the small intestine, bypassing part of the digestive tract.
-
Re-routing digestion to reduce calorie absorption and regulate gut hormones that control appetite and blood sugar.
The result is profound weight loss, enhanced satiety, and improvement in Type 2 diabetes, hypertension, and dyslipidaemia — even before substantial weight loss occurs.
Who Is It Suitable For?
Roux-en-Y gastric bypass may be recommended if you:
Have a BMI over 40, or BMI > 35 with obesity-related conditions (diabetes, sleep apnoea, joint pain).
Previously attempted sleeve gastrectomy or other methods with limited success.
Require greater metabolic benefit for diabetes or insulin resistance.
Need revision surgery after a prior bariatric procedure.
Each candidate undergoes a comprehensive pre-operative assessment, including cardiometabolic screening, nutritional analysis, and psychological readiness evaluation.

Frequently Asked Questions — Roux-en-Y Gastric Bypass
How does gastric bypass differ from sleeve gastrectomy?
Gastric bypass re-routes digestion to reduce absorption and appetite hormones, while sleeve gastrectomy only reduces stomach size. Bypass often provides stronger metabolic effects.
What weight loss can I expect?
Most patients lose 70–80 % of their excess weight within 12–18 months, provided they follow dietary and lifestyle guidance.
Will I need supplements?
Yes. Vitamin B12, iron, calcium, and multivitamins are essential to maintain long-term nutritional balance after surgery.
How long is recovery?
Hospital stay is typically two nights, with return to light work in 2–3 weeks. Strenuous activity should be avoided for 4–6 weeks.
Is the procedure covered by insurance?
Yes. Most major UK insurers recognise gastric bypass surgery under bariatric or metabolic surgery benefits. Self-pay packages are also available.
