Bariatric Surgery

Weight Loss Surgery Turkey 2025

Bariatric surgery is a group of medical procedures that help people with severe obesity lose weight by making permanent changes to the digestive system. It is the most effective long-term treatment for obesity when diet, exercise, and medication have not been sufficient.

• Reduces stomach capacity — you feel full sooner
• Alters gut hormones to reduce hunger and improve metabolism
• Resolves type 2 diabetes in 80% of cases
• Improves or eliminates hypertension, sleep apnoea, joint pain

• Typically 2–5 nights in hospital, fly home in 7 days

• Day 7: Cleared to fly home (typical)
• Weeks 2–6: Soft food phase. Resume light work.

A dedicated dietitian supports you throughout all phases via and video call.

Common Questions

All-inclusive packages start from €4,000 for gastric sleeve. This is 60–75% less than UK private prices of €11,500–€21,500.

Gastric sleeve is considered the safest and most popular procedure. Complication rates are below 2% in high-volume JCI centres.

BMI 35+ with obesity-related conditions (diabetes, hypertension), or BMI 40+ without comorbidities. Gastric balloon may be offered at BMI 30+.

5–7 nights total: 1–2 nights in hospital, 3–5 nights hotel. Surgeon-cleared to fly on day 7 for most sleeve and balloon patients.

Yes. Turkey performs 150,000+ bariatric procedures annually. Nexwell's hospital partners are JCI-accredited with complication rates matching European averages.

Gastric sleeve: 60–70% of excess weight. Gastric bypass: 70–80%. For 50 kg above ideal weight = 35–40 kg loss within 18 months.

Bariatric surgery preparation begins four to six weeks before your operation date with a liver-shrinkage diet. The liver sits directly above the stomach and must be reduced in volume for the surgeon to reach the operative field safely during laparoscopic procedures.

The standard protocol is a high-protein, very-low-calorie diet — typically between eight hundred and one thousand kilocalories per day — for two to four weeks pre-operatively. This diet eliminates glycogen reserves and reduces stored liver fat, shrinking organ volume by up to twenty percent.

Patients who do not comply with the liver diet face a higher risk of procedure conversion to open surgery if the surgeon cannot safely navigate the operative field. Before travel, your Istanbul clinical team sends the dietary protocol in writing with exact meal specifications and requires a compliance self-report.

Blood tests and an ECG for cardiac clearance must be completed at your local GP before departure — NexWell coordinates the test list and provides an English-language request letter for your GP.

Bariatric surgery is a metabolic intervention, but its long-term success depends heavily on psychological readiness and post-operative behavioural change. Patients who enter surgery expecting the procedure itself to solve their relationship with food without addressing the underlying eating habits and emotional patterns typically regain significant weight within three to five years.

Leading bariatric programmes include pre-surgical psychological evaluation not as a gatekeeping obstacle but as a diagnostic step to identify which patients need targeted support before and after the procedure. Turkey's leading bariatric centres conduct a pre-operative psychological assessment as standard. Post-operative support groups, nutritional counselling and behavioural follow-up are available on request.

NexWell case managers provide information about remote support resources in English, including UK-based bariatric dietitian networks and online support communities that align with Turkish surgical protocols.

The altered anatomy after bariatric surgery reduces the absorption of key micronutrients — iron, B12, folate, calcium and fat-soluble vitamins A, D, E and K. These deficiencies are not optional consequences of surgery; they are predictable and must be actively prevented through a lifelong supplement protocol.

Gastric bypass patients have the highest risk of micronutrient deficiency due to bypassing the duodenum and proximal jejunum where most mineral absorption occurs. Gastric sleeve patients face lower but still significant deficiency risk.

Your Istanbul clinical team provides the post-operative supplement protocol at discharge — typically two chewable multivitamins, two calcium citrate doses, B12 sublingual supplement and vitamin D daily, transitioning to capsule form after three months. Annual blood tests monitoring full blood count, iron studies, B12, folate, calcium and vitamin D are non-negotiable for all bariatric patients for life.

NexWell coordinates a post-discharge GP referral letter requesting the annual monitoring panel.

NexWell coordinates bariatric surgery at JCI-accredited Istanbul hospitals where specialist bariatric surgeons perform a minimum of three hundred procedures per year. Your case begins with a detailed medical intake: current BMI, comorbidities, previous weight loss attempts, medications and any prior abdominal surgeries that may affect the operative approach.

Based on this assessment, your case manager discusses which procedure — sleeve, bypass or mini bypass — best fits your health profile and goals before connecting you with your specific surgeon.

Your package includes the pre-operative blood test list coordination with your UK GP, liver-shrinkage diet protocol, all surgical fees, one night hospital stay, two further nights recovery accommodation at the approved hotel, airport transfers and a thirty-day post-operative check-in protocol.

NexWell provides the annual blood-test monitoring letter for your home GP as part of the post-discharge documentation package.

Most bariatric surgery patients who lose more than forty kilograms of body weight experience significant excess skin on the abdomen, upper arms, inner thighs and chest. This skin excess is a predictable consequence of dramatic weight loss and cannot be resolved through exercise or diet.

Body contouring surgery — which includes abdominoplasty, arm lift, thigh lift, body lift and breast reshaping — addresses this excess skin after weight has stabilised.

Surgeons recommend waiting twelve to eighteen months after reaching a stable plateau weight before considering body contouring, ensuring the skin has had maximum opportunity to retract and that weight is genuinely stable before investing in excision procedures.

Turkey is a major destination for post-bariatric body contouring, offering combination procedures — tummy tuck and arm lift in the same session, for example — at significantly lower cost than European private hospitals. NexWell coordinates post-bariatric body contouring as an integrated follow-on programme to bariatric surgery, managed by the same case manager who supported your initial weight loss surgery journey.
