At Belizza Health, we provide gastric sleeve surgery in Istanbul using state-of-the-art surgical equipment, international-standard materials, and comprehensive medical support, including nutritionists and psychologists to guide you through every step of your journey.
Our goal is not just weight loss—it’s helping you achieve a healthier, more fulfilling life with long-term success.
What Is Gastric Sleeve Surgery?
Gastric sleeve surgery is a bariatric procedure in which approximately 75–80% of the stomach is removed, leaving behind a slim, sleeve-shaped pouch. This significantly reduces the stomach’s capacity, so you feel full more quickly and consume fewer calories.
Additionally, the surgery affects hunger-regulating hormones, leading to reduced appetite and improved metabolism—making it both a restrictive and hormonal intervention.
Who Can Benefit from Gastric Sleeve Surgery?
You may be a good candidate for gastric sleeve in Turkey if:
- You have a BMI of 35 or above, or 30 with obesity-related health problems (e.g., diabetes, hypertension)
- You have tried diet and exercise without lasting results
Before the Surgery: What to Expect
Preparation is key. In the weeks before surgery, we recommend:
- Starting a low-carb, high-protein diet
- Avoiding alcohol and smoking
- Walking or light exercise to improve lung and heart function
-You are committed to long-term lifestyle changes
- You are between the ages of 18 and 65 (exceptions possible after evaluation)
Every patient is different. At Belizza Health, we conduct a detailed medical and psychological assessment to ensure the procedure is safe and right for you.
- Attending a pre-op consultation with our dietitian and psychologist
You will also undergo blood tests, imaging, and anesthesia evaluation
How the Procedure Works
- Performed under general anesthesia
- Duration: around 60 to 90 minutes
- Minimally invasive: done via laparoscopic (keyhole) technique
- Hospital stay: usually 2 to 3 nights
- Discharge with clear post-op instructions and medication
During the procedure, your stomach is reshaped using top-tier stapling devices, minimizing leakage risks and ensuring optimal healing.
First Weeks:
- Begin with a clear liquid diet
- Take prescribed vitamins and supplements
- Walk gently to prevent clots
Post-Surgery: Recovery & Lifestyle
After 1 Month:
- Resume normal activities with dietitian guidance
- Psychological support continues
- Noticeable weight loss (10–20 kg in 6–8 weeks)
Long-Term:
- 60–80% excess weight loss in 12–18 months
- Improvement in diabetes, PCOS, joint pain, etc.
- Monthly follow-ups (online or in-person)
What Happens Before and After the Procedure?
Before:
- Initial consultation with our doctor and dietitian
- Blood tests and imaging if needed
- 1–2 days of light diet and fasting
- For endoscopic balloons: local sedation during insertion (15-20 minutes)
After:
- Mild nausea or cramps for a few days—managed with medication
- Liquid and soft diet for the first week
- Regular check-ins with our nutritionist
- Monthly evaluations to adjust your plan and support your progress
- Balloon is removed or passed naturally depending on the type
Am I a Good Candidate for the Gastric Balloon?
This procedure may be suitable if:
- Your BMI is between 27 and 40
- You are not ready or eligible for bariatric surgery
- You need support to change eating behaviors
- You’re preparing for future surgery with required pre-op weight loss
It is not recommended for patients with prior stomach surgeries, ulcers, or significant gastroesophageal issues. A personalized medical evaluation at Belizza Health will confirm your eligibility.

Weight loss varies based on balloon type and lifestyle changes, but average results include:
- 10–20 kg reduction over 6–12 months
- Improvements in blood sugar, cholesterol, and blood pressure
