A Life-Changing Solution for Lasting Weight Loss

Obesity is more than a cosmetic issue—it is one of the world’s most serious health concerns and a leading cause of preventable death. For patients struggling with obesity and its related complications, gastric sleeve surgery has become one of the most effective treatments. At Medical Park Hospitals in Turkey, this procedure not only helps with sustainable weight loss but also improves overall health, reduces obesity-related conditions, and enhances quality of life.

🩺 What Is Gastric Sleeve Surgery (Sleeve Gastrectomy)?

Also known as sleeve gastrectomy, gastric sleeve surgery involves removing approximately 80–85% of the stomach, leaving behind a sleeve-shaped tube. This smaller stomach restricts food intake and significantly reduces appetite by lowering ghrelin hormone levels.

  • Reduces hunger hormone (ghrelin) production
  • No rerouting of intestines
  • Permanent procedure with long-term weight loss success
  • Shorter recovery and fewer complications than bypass

Best suited for: Patients with a BMI over 35 or those with obesity-related health issues.

The procedure is performed laparoscopically, ensuring:

  • Minimal scarring
  • Reduced infection risk
  • Faster recovery times

Key Features

  • Duration: 1–2 hours under general anesthesia
  • Hospital Stay: 1–2 nights
  • Recovery: Light activities within 1 week

Types of Gastric Sleeve Surgery

🩺 Standard Gastric Sleeve

The traditional method where most of the stomach is removed, leaving a tube-like pouch. This is the most commonly performed procedure worldwide.

🩺 Mini Sleeve Gastrectomy

A less extensive version of the standard procedure, ideal for patients requiring smaller stomach reduction with shorter recovery times.

🩺 Revisional Sleeve Surgery

For patients who had previous bariatric surgery (such as gastric banding) but did not achieve the desired results. This revision improves restriction and weight loss.

🩺 Extended Sleeve Gastrectomy

A more advanced procedure sometimes combined with additional steps to maximize weight loss and metabolic improvement, often for patients with severe obesity.

🧑‍⚕️ Who Is a Good Candidate?

✔️ Adults with a Body Mass Index (BMI) over 40
✔️ Patients with a BMI of 35+ and obesity-related health conditions such as diabetes, sleep apnea, or hypertension
✔️ Individuals who have struggled with weight loss through diet and exercise alone
✔️ Non-smokers or those willing to quit before surgery
✔️ Patients committed to making long-term lifestyle changes for succes

📝 Consultation & Preparation

At Medical Park, the journey begins with a thorough consultation:

✅ Complete health and medical history review

Before surgery, patients are advised to:

✅ Stop smoking, alcohol, or recreational drugs

Recovery after gastric sleeve surgery is closely supported by Medical Park’s team:

✔️ 1–2 nights hospital stay with continuous monitoring
✔️ Walking encouraged the day after surgery to prevent complications
✔️ Detailed dietary plan: starting with liquids, then purees, followed by solids
✔️ Return to light activities within 1 week and full recovery in 4–6 weeks

    I had a good experience getting seen by a Consultant Endocrinologist for ~£110 or €125 with availability on the same day. In particular, Yahya in the International Office was brilliantly attentive; an excellent translator (still very useful even though the consultant spoke fair English) who was medically literate with a clinical background. Yahya was organised & had all my notes & paperwork prepared in advance despite sending to him last minute. The hospital & international office staff were all accommodating & friendly & even went above & beyond to help a stray kitten that wandered into the building. I felt in very safe hands!

    I, Syed Irfan Haider from Pakistan, recently visited Medical Park Hospital Bahceliveler, Istanbul for exploring treatment options for my daughter with PRCA. The hospital staff including doctor, International coordinator, translator and nurses were all very friendly/cooperative. The hospital maintains a very clean/ hygenic outlook. Mr YAHYA BABAN (our translator) was all the times available to provide us with the best possible comfort, including admin support, management of hospital visits and remove any language barrier with the doctor or nursing staff. Mr Halit (Khalid Hissain), the international coordinator facilitated our hospital visit and ensured we received the highest standard of care. Since this was my first visit for initial testing/ diagnosis for my daughter, we are looking forward for the next visit soon for Bone Marrow Transplant.
