Meet Some of Our Patients Who Underwent Gastric Sleeve Surgery
What Is a Sleeve Gastrectomy (Gastric Sleeve)?
First, let’s clarify the procedure. A sleeve gastrectomy, more commonly known as a gastric sleeve, is a powerful and highly effective bariatric surgery. It is not just a restrictive procedure; it is also a metabolic one. It is performed laparoscopically (using “keyhole” incisions) for a faster, safer recovery.
The surgery works in two ways:
- It is Restrictive: Your surgeon permanently removes about 75-80% of your stomach, leaving behind a small “sleeve” about the size of a banana. This new, smaller stomach physically restricts the amount of food you can eat, helping you feel full on a much smaller portion.
- It is Hormonal: This is the most powerful part. The large, outer part of the stomach that is removed is the primary area that produces ghrelin, the “hunger hormone.” By removing it, the surgery dramatically reduces your ghrelin levels. This means your constant, nagging hunger is significantly reduced, helping you stick to your new diet.
As a surgeon with over two decades of experience, Prof. Dr. Karatepe often explains that the gastric sleeve surgery is like resetting your body’s appetite system, allowing it to work more efficiently for you, not against you.
What are the qualifications for gastric sleeve in the UK?
To qualify for bariatric surgery on the NHS, you generally need a Body Mass Index (BMI) of 40 or higher, or a BMI of 35 to 39.9 with a serious, obesity-related health condition. These conditions include high blood sugar (type 2 diabetes), high blood pressure, or severe sleep apnoea. You must also show you have tried to lose weight through non-surgical methods.

The Two Main Paths for Gastric Sleeve in the UK
For patients in the UK, there are two traditional options for gastric sleeve surgery. Both have significant barriers that can make timely care feel impossible.
1. The NHS Gastric Sleeve Pathway (The Wait)
The National Health Service (NHS) provides excellent care, but access to bariatric surgery is extremely limited and slow. The gastric sleeve waiting list in the UK is not just one list; it is a multi-year process.
- Step 1: Get a GP Referral. You must first see your GP, who will refer you to a Tier 3 weight management service.
- Step 2: The Tier 3 Programme. This is a mandatory, medically supervised diet and lifestyle program. Depending on your “postcode” (your local NHS trust), the wait to *start* this program can be over a year. The program itself typically lasts for 6 to 12 months.
- Step 3: The Surgical Wait List (Tier 4). *After* you have successfully completed the Tier 3 program, you are then placed on the official surgical waiting list. This NHS waiting list for bariatric surgery can be another 1, 2, or even 3+ years.
For many patients, this means a total wait of 2 to 5 years from their first GP appointment to their surgery day. For a patient suffering from high blood sugar or severe sleep apnoea, a 5-year wait is a serious health risk.
2. The Private UK Pathway (The Cost)
If you cannot wait years, the only other option is to pay for the surgery privately in the UK. This allows you to bypass the NHS wait, but it comes at a significant financial cost.
The private gastric sleeve cost in the UK typically ranges from £8,000 to £13,000. This price can vary depending on the surgeon’s experience, the hospital, and whether it is in London or another city. This single, upfront cost is simply not a realistic option for the vast majority of people, leaving them feeling trapped.
How much is a private gastric sleeve in the UK?
The Same-day-private gastric sleeve price UK typically ranges from £8,000 to £13,000. This self-pay price usually includes the surgeon’s fee, anaesthetist’s fee, and the hospital stay. This high cost is a major barrier for most UK patients.

A Third Option: Why UK Patients Choose Turkey for Gastric Sleeve Surgery
Because of the barriers in the UK, thousands of patients are now choosing a third option: traveling to a centre of medical excellence like Istanbul, Turkey, for their care. This is not about “cheap” surgery; it is about accessing affordable, high-quality, and immediate care.
Turkey has become a global leader in medical tourism, rivaling top clinics in Europe and the US. Here is why it has become the top choice for UK patients:
- No Waiting Lists: You can schedule your surgery with a world-class surgeon immediately. You do not have to put your health on hold for 3-5 years.
- Affordable Excellence: The gastric sleeve cost in Turkey for an *all-inclusive package* is often £2,500 to £4,500. This price is lower not because the quality is lower, but because the cost of living and operational expenses are lower.
- World-Class Hospital Standards: Top Turkish hospitals (like those used by our team) are JCI-accredited. This is the same “gold standard” accreditation that the best hospitals in the United States must earn. It is a guarantee of the highest international standards in safety and quality.
- All-Inclusive Packages: Unlike a private UK price, the price in Turkey is almost always an “all-inclusive” package. This typically includes:
- Your gastric sleeve surgery
- Your surgeon’s and anaesthetist’s fees
- A 2-3 night stay in a high-tech, private hospital room
- All your pre-operative tests (blood work, EKG, specialist checks)
- All VIP transfers (airport, hotel, hospital)
- A 4-5 star hotel stay for your recovery
For many UK patients, this means they can get their life-changing surgery, performed by a world-renowned surgeon, with no wait, for less than a third of the private UK cost.
Is it safe to go to Turkey for a gastric sleeve?
Yes, gastric sleeve surgery in Turkey is extremely safe, *provided* you choose the right surgeon and hospital. The key is to select a surgeon with extensive experience (like Prof. Dr. Karatepe) who operates in a JCI-accredited hospital. These facilities meet the same high safety standards as top hospitals in the UK or US.
Why Choose Prof. Dr. Oguzhan Karatepe for Your Sleeve Gastrectomy?
With over 25 years of experience, thousands of successful cases, and expertise in robotic and laparoscopic surgery, Prof. Dr. Karatepe is a leading figure in gastric sleeve procedures. When you are traveling for care, the surgeon’s experience and trustworthiness are your most important considerations.
A bariatric surgeon who has performed over 3,000 successful surgeries, like Prof. Dr. Karatepe, is known as a “high-volume” surgeon. This level of experience is proven to lead to lower complication rates, safer procedures, and better patient outcomes. His expertise in advanced laparoscopic and robotic surgery means your gastric sleeve is performed using the most modern, minimally invasive techniques available. This translates to real patient benefits:
- Less post-operative pain
- A shorter and more comfortable hospital stay
- Minimal gastric sleeve scars
- A faster gastric sleeve recovery
Furthermore, as a Professor of Surgery with hundreds of academic publications, Prof. Dr. Karatepe is not just a practitioner; he is an academic authority who is at the forefront of the latest, safest techniques. This is why patients from around the world, especially the UK, who are researching the “best gastric sleeve surgeons” choose our clinic. Our expert team is here to help you, and we are proud to provide personalized surgical solutions at a world-class standard.

How to choose the right gastric sleeve surgeon?
A sleeve gastrectomy is performed by a bariatric surgeon (a general surgeon with specialized fellowship training). When choosing, look for a surgeon with extensive, verifiable experience (1,000+ procedures), board certification, and academic credentials (like a Professor). Most importantly, ensure they operate in an accredited (JCI) hospital and have a strong nutritional aftercare program.
Frequently Asked Questions (FAQ) About Gastric Sleeve (for UK Patients)
Q: What is gastric sleeve surgery?
A: Gastric sleeve surgery is a weight loss operation where a surgeon removes about 75-80% of the stomach. This leaves a small, “sleeve-shaped” stomach, which restricts food intake and reduces hunger hormones, helping you lose weight effectively.
Q: What is the private gastric sleeve cost in the UK?
A: The private gastric sleeve price UK typically ranges from £8,000 to £13,000. This cost is a major reason why many patients seek affordable, high-quality care abroad in places like Turkey.
Q: How long is the NHS bariatric surgery waiting list?
A: The total wait time can be 2 to 5 years. This includes the wait for the mandatory Tier 3 weight management program (which can be over a year) *plus* the surgical (Tier 4) waiting list, which can be another 1-3 years.
Q: How much weight will I lose with a gastric sleeve?
A: On average, patients lose 60% to 70% of their excess body weight within 12 to 18 months. This depends on your commitment to the post-op lifestyle changes.
Q: How long do I need to stay in Turkey for the surgery?
A: For UK patients, the trip is very convenient. You will typically stay in Istanbul for 7 to 9 days. This includes your pre-op tests, your 2-3 night hospital stay, and a few days of recovery in your hotel before your final check-up and flight home.
Q: How long do I need off work?
A: Most patients (including our patients from the UK) who have a desk job can plan to return to work in 2 to 3 weeks. If your job is physically demanding, you will need 4-6 weeks off.
Q: What are the risks of gastric sleeve surgery?
A:Gastric sleeve is very safe. However, like any surgery, it has rare risks (less than 1-2% with an expert surgeon) like bleeding, infection, blood clots, and a staple line leak. Choosing an experienced surgeon is the best way to minimize these risks.
Q: What is a JCI-accredited hospital?
A: JCI (Joint Commission International) is the global “gold standard” for hospital safety and quality. It is the same accreditation that top hospitals in the US must earn. Choosing a JCI-accredited hospital in Turkey ensures you are in a facility that meets the highest international standards.
Q: What is the diet after gastric sleeve?
A: You will follow a 4-stage post-op diet, starting with clear liquids, then full liquids/purees, then soft foods, and finally, solid foods (around week 7). This phased approach is critical for letting your new stomach sleeve heal.
Q: Is the gastric sleeve reversible?
A: No. The gastric sleeve surgery is irreversible, as the majority of the stomach is permanently removed from the body.
Q: Do doctors in Turkey speak English?
A: Yes. Top surgeons like Prof. Dr. Karatepe and their entire medical teams are fluent in English. The hospitals are designed for international patients, so all communication is clear and easy.
