At Carely Clinic, we specialize in advanced gastric bypass procedures to help you achieve sustainable weight loss and improved overall health.
Obesity is a chronic health condition that affects not just your body, but your mind and daily life. If diet, exercise, or medications haven’t worked, gastric bypass surgery is a powerful tool to take back control of your health and future.
Turkey has earned international recognition for offering high-quality bariatric surgeries at affordable prices. At Carely Clinic, we help you lose weight safely with the support of top-tier bariatric surgeons, accredited hospitals, and a compassionate medical team guiding you every step of the way.
Struggling with severe obesity despite numerous diet attempts? Gastric bypass in Turkey might be your turning point. Each year, thousands of international patients choose Istanbul for this gold-standard bariatric procedure, combining world-class medical expertise with costs 65-75% lower than Western countries. The appeal is clear—top-tier surgeons, state-of-the-art hospitals, and comprehensive care packages that include luxury recovery accommodation.
At Carely Clinic Istanbul, we specialize in Roux-en-Y gastric bypass surgery, the most effective and well-studied bariatric procedure available. Our international patients achieve remarkable results—averaging 80% excess weight loss within 18 months—while enjoying significant savings compared to UK, US, or European prices. But is gastric bypass in Turkey the right choice for your weight loss journey? Let’s explore everything you need to know.
Gastric bypass—technically called Roux-en-Y gastric bypass—is considered the “gold standard” of weight loss surgeries. Unlike simpler procedures like gastric sleeve, bypass creates both restrictive and malabsorptive effects, delivering more powerful and consistent weight loss results.
During this sophisticated laparoscopic procedure, our surgeons in Turkey create a small egg-sized stomach pouch (approximately 30ml capacity) separated from the rest of your stomach. This drastically limits food intake. Then, we bypass a portion of the small intestine by connecting the new stomach pouch directly to the middle section of the small intestine (jejunum).
This dual-action approach works through three powerful mechanisms:
The result is not just rapid weight loss, but often dramatic improvement in obesity-related conditions like type 2 diabetes—sometimes within days, even before significant weight loss occurs. This “metabolic effect” explains why gastric bypass remains the procedure of choice for patients with severe diabetes or metabolic syndrome despite the growing popularity of sleeve gastrectomy.
Research in the New England Journal of Medicine (2023) confirms that gastric bypass provides superior long-term weight maintenance compared to other bariatric procedures, with patients maintaining an average of 70% excess weight loss at the 10-year mark.
Choosing gastric bypass surgery in Turkey delivers life-changing benefits that extend far beyond weight loss:
“After years of feeling trapped in my body, my gastric bypass in Istanbul freed me. I’ve lost 52kg in 14 months, my diabetes is completely gone, and I’ve reduced my blood pressure medications from three to zero. The procedure was surprisingly comfortable, and the care I received in Turkey surpassed anything I’ve experienced in London hospitals. This wasn’t just surgery—it was the beginning of my second life.” —Michael, 43, Manchester
These transformative results explain why patients travel from across Europe, North America, and the Middle East to access affordable gastric bypass surgery in Turkey with our specialist team.
Gastric bypass surgery requires careful candidate selection to ensure safety and maximize success. Our comprehensive assessment evaluates:
| Criteria | Ideal Candidate | May Need Assessment | Likely Not Suitable |
|---|---|---|---|
| BMI | 40+ or 35+ with comorbidities |
30 – 34.9 with severe diabetes |
Under 30 |
| Age | 18 – 65 | 66 – 72 (case-by-case) | Under 18 or over 72 |
| Health history | Failed structured weight-loss programs |
Limited documented attempts |
No previous serious attempts |
| Medical conditions | Stable, controlled conditions | Conditions requiring pre-op optimisation |
Severe uncontrolled conditions |
| Psychological readiness | Understands lifelong changes | Concerns about commitment | Active eating disorders |
| GI health | No significant GI issues | Mild reflux or ulcer history | Severe IBD or previous complex GI surgery |
| Substance use | No smoking / alcohol dependence | Recent quitter (≥ 3 months) | Active substance abuse |
During your free virtual consultation, our bariatric specialists will conduct a thorough evaluation of your medical history, current health status, and weight loss goals to determine if gastric bypass in Turkey is appropriate for you.
Because gastric bypass creates permanent anatomical changes, we place special emphasis on psychological readiness and commitment to lifelong dietary and lifestyle modifications. Our pre-operative psychological assessment ensures you’re fully prepared for the transformative journey ahead.
Gastric bypass is highly effective, but—like any major surgery—it carries specific risks. Early complications may include bleeding, infection, blood clots (DVT/PE) and an anastomotic leak. Carely Clinic’s leak rate is < 0.3 % (global average 1–3 %). Mid-term issues can involve marginal ulcers, internal hernia, or bowel obstruction. Long-term concerns include dumping-syndrome episodes (rapid heartbeat, dizziness after sugary meals), chronic iron- or B-12-deficiency anaemia, fat-soluble-vitamin deficiency, and—in <10 % of cases—reactive hypoglycaemia. Because part of the small intestine is bypassed, lifelong multivitamins, calcium + D, iron and B-12 injections are mandatory. We mitigate risks with intra-op leak testing, routine closure of mesenteric defects, ERAS pain protocols, early mobilisation, and a 24-month dietitian-led follow-up. Your personalised risk profile will be reviewed in detail during your pre-operative consultation.

Gastric bypass is more complex and creates both restrictive (smaller stomach) and malabsorptive (reduced absorption) effects, while sleeve gastrectomy is purely restrictive. Bypass typically produces greater weight loss (80% of excess weight vs. 70% with sleeve) and superior resolution of diabetes due to its more powerful metabolic effects. However, bypass requires stricter lifelong vitamin supplementation and monitoring due to the malabsorptive component. The ideal procedure depends on your specific health profile, weight loss goals, and medical conditions—which we'll evaluate during your consultation.
At Carely Clinic, our complication rates are significantly below international averages due to our high surgical volume and specialized focus. Our serious complication rate is approximately 1.2% (compared to 3-5% in many Western centers). Specifically, our leak rate is 0.2%, internal hernia rate 0.5%, and major bleeding rate 0.3%. These exceptional safety statistics reflect our surgeons' extensive experience (1,000+ bypass procedures each) and our comprehensive pre-operative optimization protocols. Every procedure includes complication insurance covering any potential surgical revision needed within the first year.
Yes, lifelong supplementation is non-negotiable after gastric bypass surgery. The bypass component of the procedure affects nutrient absorption, particularly vitamin B12, iron, calcium, and fat-soluble vitamins (A, D, E, K). Clinical studies show that without proper supplementation, over 50% of bypass patients develop nutritional deficiencies within 2 years (Journal of Clinical Endocrinology & Metabolism, 2024). Our protocol includes a specialized multivitamin, sublingual B12, calcium citrate with vitamin D, and regular blood monitoring to prevent deficiencies. With proper supplementation, serious nutritional problems are rare, and most patients report the supplement regimen becomes a simple daily routine.
Most patients return to desk-based or light physical work within 3-4 weeks after surgery. More physically demanding occupations typically require 6-8 weeks of recovery. Our Turkish patients typically take 2-3 weeks off work, while international patients generally schedule 3-4 weeks away from professional responsibilities to account for travel and initial recovery. Your return-to-work timeline depends on your specific job requirements, overall health, and individual healing progress. Our medical team provides customized return-to-work documentation based on your particular situation.
While technically reversible, gastric bypass reversal is complex and rarely performed (less than 1% of cases). Reversal is typically only considered for severe complications that cannot be managed through less invasive means, such as extreme malnutrition resistant to supplementation. The reversal procedure carries its own risks and usually results in significant weight regain. Rather than reversal, complications are typically managed through nutritional interventions, endoscopic procedures, or more limited surgical revisions that preserve the weight loss benefits while addressing specific issues.
Most patients experiencing significant weight loss (typically 40+ kg) develop some degree of loose skin, particularly around the abdomen, arms, thighs, and chest. The extent varies based on age, genetics, initial weight, weight loss rate, exercise habits, and smoking status. Approximately 60-70% of our gastric bypass patients pursue some form of body contouring after reaching their stable weight (typically 18-24 months post-surgery). Many patients return to Turkey for these procedures due to the significant cost savings compared to Western plastic surgery prices. We offer combined packages for patients planning future body contouring procedures.
Gastric bypass produces remarkable effects on type 2 diabetes, with approximately 85-90% of patients experiencing complete remission or significant improvement. Most notably, these improvements often occur days after surgery—before significant weight loss—due to hormonal and metabolic changes caused by rerouting the digestive tract. A landmark study in The Lancet (2023) demonstrated that 78% of bypass patients maintained diabetes remission at 5 years post-surgery. Patients with shorter diabetes duration, higher insulin production, and better controlled blood sugar before surgery achieve the best results. Our specialized "diabetes optimization protocol" for pre-operative patients maximizes these benefits.
