What Is Sleeve Gastrectomy (Vertical Sleeve Gastrectomy)?

At Avolin Health, we connect you with Turkey’s top-tier bariatric surgeons and JCI-accredited hospitals to ensure a safe and successful weight loss journey.

Sleeve gastrectomy, also known as VSG, is a widely performed bariatric procedure that has revolutionized the treatment of morbid obesity. For individuals who struggle to lose weight through traditional methods, this minimally invasive surgery offers a powerful and life-changing intervention.

How Is Sleeve Gastrectomy Performed?

The procedure involves removing approximately 75–80% of the stomach, leaving behind a narrow, tube-like “sleeve.” This transformation works through two primary mechanisms:

  • Restrictive Weight Loss: By significantly reducing the stomach’s capacity, it limits food intake and promotes early satiety.
  • Hormonal Regulation: The removal of the portion of the stomach responsible for producing "Ghrelin" (the hunger hormone) leads to a natural decrease in appetite and better blood sugar control.

The Avolin Health Standard of Care

As a premier medical tourism agency, we meticulously coordinate every aspect of your bariatric surgery in Turkey:

  • Holistic Evaluation: We manage your comprehensive pre-operative assessments, including nutritional counseling and medical clearance.
  • Proven Results: Most patients lose up to 60–70% of their excess body weight within the first year, often resolving obesity-related conditions such as type 2 diabetes and hypertension.
  • Full-Service VIP Management: From seamless VIP transfers and luxury accommodations to professional post-operative dietary support, Avolin Health ensures you are supported every step of the way toward a healthier future.

Why Choose Avolin Health for Gastric Sleeve Surgery?

Reclaiming your health and reaching your ideal weight is a transformative journey. At Avolin Health, we provide Gastric Sleeve Surgery (Sleeve Gastrectomy)—a gold-standard bariatric procedure designed to help you achieve significant, long-term weight loss and reverse obesity-related health conditions.

1. Specialized Bariatric Expertise

Your safety depends on the skill of your surgeon. Avolin Health works exclusively with Turkey’s top-tier bariatric surgeons who have performed thousands of successful sleeve procedures. Our surgeons utilize advanced laparoscopic (closed) techniques, ensuring high precision, smaller incisions, and a lower risk of complications.

2. Comprehensive Metabolic Transformation

Gastric Sleeve is more than just reducing stomach size; it’s about hormonal balance. By removing the portion of the stomach that produces the "hunger hormone" (ghrelin), our procedure helps naturally curb your appetite and jumpstart your metabolism, leading to sustainable weight loss that lasts a lifetime.

3. Dedicated Post-Operative Support

The surgery is the beginning, not the end. We provide an integrated follow-up system, including personalized nutritional counseling and lifestyle guidance. Our goal is to ensure you adapt comfortably to your new body and maintain your results through healthy, guided habits.

4. A VIP Health Journey in Istanbul

Frequently Asked Questions

What is Gastric Sleeve surgery and how does it facilitate weight loss?
Gastric Sleeve is a surgical procedure where approximately 80% of the stomach is removed, leaving a banana-shaped "sleeve." At Avolin Health, this method reduces stomach capacity and removes the area responsible for secreting the hunger hormone (Ghrelin), leading to increased satiety.
Who is a suitable candidate for Gastric Sleeve surgery?
Ideal candidates are individuals with a Body Mass Index (BMI) of 35 or higher, or those with a BMI over 30 who suffer from obesity-related health issues like diabetes or hypertension. Avolin Health specialists evaluate your suitability through detailed pre-operative tests.
Is the surgery performed using the laparoscopic method?
Yes. The operation is performed entirely laparoscopically through a few small incisions. Thanks to this technique used at Avolin Health, patients experience less pain, faster recovery, and no large surgical scars.
How much weight can I expect to lose after surgery?
Patients typically lose between 60% and 80% of their excess body weight within the first year. With the guidance of Avolin Health dietitians, this weight loss is achieved in a healthy and sustainable manner.
What is the risk of a "leak" after the operation?
The risk of a leak is very low due to modern surgical techniques and advanced technological equipment. Avolin Health minimizes all risks by employing experienced surgeons and strictly following international safety protocols.
What will my diet look like after surgery?
The first few weeks follow a liquid and soft-food (puree) phase. Gradually, solid foods are reintroduced. Avolin Health nutritionists provide a personalized guide to help you establish lifelong healthy eating habits.
Will I need to take vitamin and mineral supplements?
Since stomach capacity is reduced and food intake is lower, regular vitamin and mineral supplements are essential, especially during the first year. Avolin Health monitors your blood test results regularly to manage your supplementation needs.
How does Avolin Health manage the process for international patients?
We plan a 6-7 day stay in Istanbul for our international guests. Avolin Health provides a complete service including VIP airport transfers, full-service hospital accommodation, expert surgical consultations, and lifelong online dietary support.
