Weight loss surgery — also known as bariatric surgery, obesity surgery, or metabolic surgery — is a group of surgical and non-surgical procedures that help patients with severe obesity achieve significant, lasting weight loss when diet, exercise, and medication have failed. The World Health Organisation estimates that over 1 billion people worldwide now live with obesity, making it one of the most pressing chronic health conditions of the 21st century.
Weight loss surgery works by reducing stomach capacity, altering hormonal signals that control hunger, or both. Published research in The Lancet (2022) confirms that bariatric surgery delivers significantly greater and more sustained weight loss than any non-surgical intervention — including the newest GLP-1 receptor agonist medications such as Ozempic and Wegovy.
At MedProper Istanbul, we offer the full range of weight loss procedures in a JCI-accredited hospital, with all-inclusive packages starting from £1,543. Whether you need a gastric sleeve, gastric bypass, gastric balloon, or revisional surgery, our IFSO-member bariatric team will recommend the procedure best suited to your BMI, health profile, and weight loss goals.
Price is the first question most patients ask. Turkey offers a dramatic cost advantage for weight loss surgery compared to both the UK and the USA. All MedProper prices are all-inclusive — there are no hidden charges.
| Procedure | MedProper (GBP) | MedProper (EUR) | UK Private | USA Private |

At MedProper Istanbul, weight loss surgery starts from £1,275 / €1,490 for a gastric balloon and from £1,925 / €2,250 for a gastric sleeve. Gastric bypass starts from £2,695 / €3,150. All prices are all-inclusive — surgeon fee, hospital, hotel, transfers, tests, medications, supplements, and 12-month aftercare. There are no hidden charges.
Yes, when performed at an accredited facility by an experienced bariatric surgeon. MedProper operates in a JCI-accredited hospital with Level 3 intensive care, IFSO-member surgeons, dual leak testing, and 24-hour post-operative monitoring. The mortality rate for gastric sleeve at experienced centres is 0.08-0.19% — comparable to routine gallbladder surgery.

Even after adding a return flight — typically £100-£250 from London or $400-$700 from New York via Turkish Airlines — the total cost at MedProper is a fraction of UK or US prices.
The cost difference is not a quality difference. Turkey's lower operating costs (staffing, hospital infrastructure, property), favourable exchange rate, and government-backed medical tourism incentives allow JCI-accredited hospitals to deliver equivalent or superior care at dramatically lower prices. Turkish bariatric surgeons perform over 50,000 procedures annually — higher case volumes than most UK or European surgeons — and Turkey has 72 JCI-accredited hospitals, more than any European country.
Every MedProper weight loss surgery package includes:
Companion accommodation: Your travel companion stays in the same hotel room at no additional charge. Unlike some competitors, MedProper does not charge extra for companion accommodation.
There are no hidden charges. The price you are quoted is the price you pay.
MedProper offers six weight loss procedures, from non-surgical options to complex revisional surgery:
| Procedure | Type | BMI Range | Expected Weight Loss | Duration | Hospital Stay |
|---|---|---|---|---|---|
| Gastric Sleeve | Surgical | 35+ (30+ with comorbidities) | 60-70% of excess weight | 45-75 min | 2-4 nights |
| Gastric Bypass | Surgical | 40+ (35+ with comorbidities) | 65-75% of excess weight | 90-150 min | 3-5 nights |
| Mini Gastric Bypass | Surgical | 40+ | 65-75% of excess weight | 60-90 min | 3-4 nights |
| Banded Sleeve | Surgical | 35+ | 60-70% of excess weight | 50-80 min | 2-4 nights |
| Gastric Balloon | Non-surgical | 27-35 | 10-15% of total body weight | 15-20 min | Day case |
| Revisional Surgery | Surgical | Any (prior bariatric surgery) | Varies | 90-180 min | 3-5 nights |
The most commonly performed weight loss surgery worldwide, accounting for approximately 55% of all bariatric procedures globally. The surgeon removes 75-80% of the stomach laparoscopically, leaving a narrow tube-shaped pouch. The procedure is irreversible, takes 45-75 minutes, and produces 60-70% excess weight loss within 12-18 months.
Best for: BMI 35-45 without severe acid reflux. Patients seeking a single, definitive operation with strong results and lower vitamin requirements than bypass.
The gold standard for metabolic surgery. A small stomach pouch (approximately 30 ml) is created and connected directly to the small intestine, bypassing most of the stomach and duodenum. This dual mechanism — restriction plus malabsorption — produces higher average weight loss and superior Type 2 diabetes remission (80%+) compared to gastric sleeve.
Best for: BMI over 45, poorly controlled Type 2 diabetes, or chronic gastroesophageal reflux disease (GORD). Bypass resolves reflux in over 90% of cases.
A silicone balloon placed endoscopically into the stomach under light sedation. No incisions, no general anaesthesia, and fully reversible. The balloon remains for 6-12 months, creating early satiety. Ideal for patients with BMI 27-35 who do not qualify for surgical procedures.
A standard gastric sleeve combined with a silicone ring placed around the upper portion of the new stomach. The band prevents the sleeve from stretching over time, potentially improving long-term weight maintenance.
Between 15% and 25% of bariatric patients require revision within ten years (SOARD data). MedProper offers sleeve-to-bypass conversion and re-sleeve procedures for patients with weight regain, sleeve stretching, or severe reflux after a previous operation.
| Your Profile | Recommended Procedure | Why |
|---|---|---|
| BMI 27-35, no comorbidities | Gastric Balloon | Non-surgical, reversible, ideal starting point |
| BMI 35-45, no severe reflux | Gastric Sleeve | Most popular, strong results, lower supplement needs |
| BMI 40+, Type 2 diabetes | Gastric Bypass | Highest diabetes remission (80%+), best metabolic outcomes |
| BMI 40+, chronic GORD | Gastric Bypass | Resolves reflux in 90%+ of cases (sleeve may worsen it) |
| Sweet-eating pattern | Gastric Bypass | Creates "dumping syndrome" which discourages sugar consumption |
| Previous bariatric surgery, weight regain | Revisional Surgery | Sleeve-to-bypass conversion or re-sleeve |
| Want long-term protection against stretching | Banded Sleeve | Silicone ring prevents dilation over time |
Your MedProper surgeon will analyse your full medical profile during a free consultation and recommend the optimal procedure. There is no one-size-fits-all solution.
Only approximately 6,000 NHS bariatric procedures are performed annually in England, despite an estimated 2.9 million adults meeting NICE criteria. Regional waiting times vary dramatically:
| Region | Average Wait for Bariatric Surgery |
|---|---|
| London | 28 months |
| Yorkshire | 30 months |
| Scotland | 22 months |
| National average (England) | 24-36 months |
Most CCGs require BMI over 50 for fast-track referral or mandate a 24-month Tier 3 weight management programme before surgical referral is even considered.
| Cost Component | MedProper Istanbul | UK Private Clinic | USA Private Clinic |
|---|---|---|---|
| Surgeon fee | Included in package | £3,000-£5,000 | $8,000-$15,000 |
| Operating facility and theatre | Included | £1,000-£2,000 | $3,000-$5,000 |
| Anaesthesia (general) | Included | £500-£1,000 | $1,000-$2,000 |
| Hospital stay (2-4 nights) | Included | £500-£1,000/night | $1,000-$2,000/night |
| Hotel (3-5 nights, 4-star minimum) | Included | N/A (home recovery) | N/A |
| VIP airport transfers | Included | N/A | N/A |
| Pre-operative blood work + imaging | Included | £200-£400 | $500-$1,000 |
| Post-operative medications + supplements | Included | £50-£150 | $100-$300 |
| 12-month dietitian follow-up | Included | £100-£250/visit | $200-$400/visit |
| Total | from £2,185 | £5,350-£9,800+ | $13,800-$25,700+ |
At MedProper, the total all-inclusive cost — including hospital, hotel, and 12-month aftercare — is often less than the anaesthesia fee alone at a top US hospital.
Safety is the number one concern for patients considering weight loss surgery abroad. This section addresses the most searched safety questions directly.
The mortality rate for laparoscopic sleeve gastrectomy at experienced, JCI-accredited centres is approximately 0.08 to 0.19 per cent — roughly 1 in 500 to 1 in 1,250. This is comparable to the mortality rate for laparoscopic gallbladder removal, one of the most commonly performed surgeries worldwide. Gastric bypass carries a slightly higher rate of 0.2-0.5% due to greater surgical complexity.
For context, the long-term mortality risk of untreated severe obesity (BMI over 40) far exceeds the surgical risk. A 2024 meta-analysis in The Lancet demonstrated that bariatric surgery reduces all-cause mortality by 50-70% over a 10-year follow-up.
Red flags when choosing a clinic: No named surgeon, unusually low prices with hidden extras, no JCI or equivalent accreditation, limited post-operative support, no leak testing protocol, pressure to book immediately.
Green flags (what to look for): JCI or equivalent accreditation, named surgeon with IFSO membership, transparent all-inclusive pricing, comprehensive aftercare programme, published safety protocols, and willingness to decline patients who are not suitable candidates.
One of the most significant benefits of weight loss surgery is its effect on Type 2 diabetes — an outcome so dramatic that the medical community increasingly refers to these procedures as "metabolic surgery."
| Procedure | Type 2 Diabetes Remission Rate |
|---|---|
| Gastric Bypass (Roux-en-Y) | 80%+ |
| Gastric Sleeve | ~60% |
| Gastric Balloon | Improvement (not remission) |
Remission often occurs within days of surgery, before significant weight loss, due to hormonal and metabolic changes — particularly altered GLP-1 and bile acid signalling. A 2022 IFSO position statement now recommends metabolic surgery for patients with BMI 30-34.9 and poorly controlled Type 2 diabetes, even below traditional surgical thresholds.
GLP-1 receptor agonists (Ozempic, Wegovy, Mounjaro) have transformed obesity treatment, but they are not a replacement for surgery:
| Factor | GLP-1 Medications | Weight Loss Surgery |
|---|---|---|
| Weight loss | 15-20% of total body weight | 25-35% of total body weight |
| Diabetes remission | Improvement, rarely full remission | 60-80%+ full remission |
| Duration | Must take indefinitely | One-time procedure |
| Monthly cost (UK) | £200-£300/month ongoing | One-time from £2,185 |
| Weight regain on stopping | 60-70% regain within 12 months | 5-15% regain at 5 years |
| Side effects | Nausea, diarrhoea, pancreatitis risk | Surgical risks (see safety section) |
| Best for | BMI 27-35, medication-responsive | BMI 35+, lasting results |
Key insight: Over 5 years, GLP-1 medications at £300/month cost £18,000 — nearly 10 times the cost of a gastric sleeve at MedProper (£2,185), with inferior weight loss and diabetes outcomes.
Some patients use GLP-1 medications as a bridge to surgery or as post-surgical support for stubborn weight plateaus.
| Phase | Duration | What You Eat | Key Rule |
|---|---|---|---|
| 1. Clear liquids | Days 1-3 | Water, broth, sugar-free jelly | Sip slowly, 30ml at a time |
| 2. Full liquids | Days 4-14 | Protein shakes, smooth soups, yoghurt drinks | 60g protein/day target |
| 3. Pureed foods | Weeks 3-4 | Blended vegetables, hummus, scrambled egg | No lumps, smooth consistency |
| 4. Soft foods | Weeks 5-6 | Soft fish, cottage cheese, mashed vegetables | Chew thoroughly, small portions |
| 5. Regular meals | Week 7+ | All foods in small portions | Stop when full, protein first |
MedProper provides a detailed 12-month nutrition guide and ongoing dietitian support via video consultations.
Most UK GPs will provide ongoing monitoring (blood tests, prescriptions) after weight loss surgery performed abroad, provided you share your surgical report. MedProper provides:
Some patients report that their GP is reluctant to provide aftercare for surgery performed abroad. The Medical Protection Society (MPS) has published guidance confirming that GPs have a professional obligation to provide appropriate follow-up care regardless of where surgery was performed.
The best procedure depends on your BMI and health conditions. Gastric balloon suits BMI 27-35. Gastric sleeve is optimal for BMI 35-45 without severe reflux. Gastric bypass is recommended for BMI over 45, poorly controlled Type 2 diabetes, or chronic acid reflux. Your MedProper surgeon will recommend the right procedure during a free consultation.
Most patients lose 60-75% of excess body weight within 12-18 months after surgical procedures (sleeve or bypass). Gastric balloon patients typically lose 10-15% of total body weight over 6 months. Long-term data shows 51-54% excess weight loss maintained at 10 years for sleeve gastrectomy.
The mortality rate for laparoscopic gastric sleeve at experienced, JCI-accredited centres is approximately 0.08-0.19% — roughly 1 in 500 to 1 in 1,250. Gastric bypass carries a rate of 0.2-0.5%. For context, untreated severe obesity carries a significantly higher long-term mortality risk than either procedure.
At MedProper, patients with BMI 30-35 may qualify for surgery if they have obesity-related comorbidities such as Type 2 diabetes, hypertension, sleep apnoea, or PCOS. This follows IFSO international guidelines. The NHS typically requires BMI 40+ or 35+ with comorbidities. For BMI 27-30, a gastric balloon may be suitable.
Most patients stay 7-8 days total: 2-5 nights in hospital (depending on procedure) followed by 3-5 nights in a partnered hotel. Gastric balloon patients can return home after 2-3 days. Your MedProper coordinator will provide a detailed day-by-day itinerary before you travel.
NHS waiting lists for bariatric surgery in England typically exceed 2-3 years. London averages 28 months, Yorkshire 30 months, Scotland 22 months. Many CCGs require BMI over 50 for fast-track referral or mandate a 24-month Tier 3 programme. Only ~6,000 NHS procedures are performed annually despite ~2.9 million eligible adults. At MedProper, the wait is 2-4 weeks.
MedProper requires a deposit at booking with the balance due before surgery. While MedProper does not directly offer monthly payment plans, many patients use medical finance providers available in the UK (from approximately £110/month). The all-inclusive price starting from £1,925 makes this significantly more manageable than UK alternatives.
MedProper provides 12-month aftercare including 24/7 WhatsApp access to your medical team, scheduled video consultations, and dietary guidance. MedProper's mandatory complication insurance (required by Turkish Ministry of Health) covers treatment costs if a complication requires in-person care.
GLP-1 agonists produce 15-20% total body weight loss — significant but less than surgery (25-35%). They must be taken indefinitely at £200-£300/month; 60-70% of weight is regained within 12 months of stopping. Over 5 years, GLP-1 medications cost approximately £18,000 versus £1,925 for a gastric sleeve at MedProper. Surgery also has superior diabetes remission rates (60-80%+ vs improvement only with medication).
Most UK GPs will provide ongoing monitoring after surgery abroad when you share your surgical report and discharge summary. MedProper provides a comprehensive GP aftercare letter with your procedure details, supplement protocol, and recommended blood test schedule. The Medical Protection Society (MPS) confirms GPs have a professional obligation to provide appropriate follow-up regardless of where surgery was performed.
Contact MedProper via the website form, WhatsApp, or email. Provide your height, weight, medical history, and any previous weight loss attempts. Within 48 hours you receive a personalised assessment confirming eligibility and an exact all-inclusive price. If you decide to proceed, pay the deposit and your coordinator arranges everything — surgery date, pre-operative instructions, hotel, transfers, and preparation guide.
Weight loss surgery should not be combined with cosmetic procedures in the same session. However, many patients return to MedProper 12-18 months later for body contouring such as tummy tuck, arm lift, or breast lift to address loose skin after significant weight loss.
MedProper performs weight loss surgery on patients aged 18-65 as standard. Patients over 65 are assessed on a case-by-case basis. For patients under 18, bariatric surgery is only considered in exceptional circumstances with specialist paediatric involvement.
