Treatment Options at Florence Nightingale
Medical Weight Management & GLP-1 Treatment
Supervised treatment with GLP-1 medication such as semaglutide or tirzepatide, alongside a diet. Effective and appropriate for many patients — with an honest conversation about long-term use and what happens if you stop.
Laparoscopic Sleeve Gastrectomy
The most common bariatric operation worldwide. About 80% of the stomach is removed, cutting both capacity and the hunger hormone it produces. Typically 2–3 nights in hospital.
Gastric Bypass (Roux-en-Y)
Reduces the stomach and reroutes part of the small intestine, often the better choice for significant reflux or type 2 diabetes. Lifelong vitamin supplementation isn’t optional afterwards.
Metabolic Surgery for Type 2 Diabetes
Surgery chosen primarily to improve blood sugar control rather than weight alone. Many patients see real improvement, and your endocrinologist gives you an honest estimate of the odds rather than a promise.
Revisional Bariatric Surgery
Conversion or revision after a previous procedure — for weight regain, reflux or complications. More demanding than first-time surgery, and assessed carefully.
Body Contouring After Weight Loss
Arm, thigh and body lifts once your weight has been stable for several months — increasingly requested by patients who’ve lost significant weight on GLP-1 medication.
Type 2 Diabetes & Insulin Resistance
Full endocrine management — medication, insulin where needed, continuous glucose monitoring and complication screening.
Metabolic Syndrome & Fatty Liver (MASLD)
Managing the cluster that usually travels with excess weight: high blood pressure, high cholesterol, insulin resistance and fatty liver.
Psychological Support & Eating Behaviour
Assessment and support around emotional eating and the psychological adjustment after rapid weight change — part of the programme, not an optional extra.
How We Decide What Fits
BMI & Comorbidity Thresholds
Broad guidelines are a starting point; the full metabolic work-up is what actually confirms eligibility.
GLP-1 vs. Surgery
Reflux severity, diabetes duration, insulin reserve and how much weight loss you need shape whether medication, surgery, or both in sequence makes sense.
Pre-Operative Liver Shrinkage Diet
A short low-calorie diet before surgery shrinks the liver and makes the operation safer; skipping it is a common reason surgery gets delayed on the day.
Sleeve vs. Bypass
Reflux severity and diabetes status usually settle this more than personal preference does.
Vitamin & Mineral Monitoring After Bypass
Which deficiencies get checked, how often, and why skipping this causes damage that's often irreversible.

Common Questions
Do I qualify for bariatric surgery?
Generally from a BMI of 40, or 35 with a condition like diabetes or sleep apnoea. Send your details and we’ll tell you where you actually stand.
Sleeve or bypass — which is better?
Neither, universally. Sleeve is simpler; bypass tends to have a stronger effect on diabetes and reflux, at the cost of stricter lifelong supplementation. Your case decides it.
Should I try GLP-1 instead of surgery?
It’s a genuine alternative for many patients, but weight typically returns once you stop, meaning ongoing cost. We’ll give you the real numbers for both rather than steering you toward the one we perform.
What follow-up do I get once I’m home?
Scheduled video reviews, a blood monitoring schedule and written reports for your own doctor. If care stops at the airport, it isn’t a real bariatric programme.
What does it cost?
We quote after assessing your case, itemised by procedure, technique and follow-up.
