Istanbul / Turkey
Choosing to undergo weight loss surgery is a monumental decision—one that marks the beginning of a healthier, more vibrant chapter of your life. For many international patients, Turkey has become the premier destination for this transformation, offering world-class surgical expertise at a fraction of the cost found in the UK, Europe, or North America.
At Booking Surgery, we understand that the most common question patients ask is: "Which procedure is better for me: Gastric Sleeve or Gastric Bypass?" Both are highly effective, but they work in different ways and suit different medical profiles. In this comprehensive guide, we will break down the differences, benefits, and considerations for each to help you make an informed choice for your journey in Turkey.
The Gastric Sleeve has rapidly become the most performed weight loss surgery worldwide. Its popularity is due to its straightforward nature and impressive results.
During a Gastric Sleeve procedure, our surgeons use minimally invasive laparoscopic techniques to remove approximately 75-80% of your stomach. What remains is a narrow, tube-like "sleeve" about the size and shape of a banana.
Restriction: With a much smaller stomach, you feel full after eating only a small amount of food.
Hormonal Change: The portion of the stomach removed is responsible for producing Ghrelin, the "hunger hormone." By reducing Ghrelin levels, most patients report a significant decrease in appetite and cravings.
No rerouting of the intestines.
Lower risk of long-term vitamin deficiencies compared to bypass.
Highly effective for those with a BMI between 30 and 45.
Generally a shorter operative time.
The Gastric Bypass is often referred to as the "Gold Standard" of bariatric surgery. It is a slightly more complex procedure that has been performed successfully for decades.
Gastric Bypass involves two main steps. First, the surgeon creates a small pouch at the top of the stomach. Second, a section of the small intestine is connected directly to this pouch, "bypassing" the rest of the stomach and the first part of the small intestine.
Restriction: Like the sleeve, the small pouch limits food intake.
Malabsorption: Because part of the small intestine is bypassed, your body absorbs fewer calories and nutrients from the food you eat.
Metabolic Shift: It is exceptionally effective at altering gut hormones that affect blood sugar, making it the preferred choice for patients with severe Type 2 Diabetes.
Superior results for patients with severe Acid Reflux (GERD).
Often leads to faster and slightly higher total weight loss.
Excellent for resolving metabolic syndromes and diabetes.

When you book through Booking Surgery, you aren't just getting a medical procedure; you are getting a VIP experience in one of the world's most beautiful cities.
Turkish bariatric surgeons are among the most experienced in the world. Due to the high volume of international patients, our surgeons at Booking Surgery perform these procedures daily, honing a level of precision that minimizes complications and maximizes aesthetic and functional results.
We partner with JCI-accredited hospitals in Istanbul that exceed international standards. From high-tech operating theaters to luxury private recovery suites, your safety and comfort are our priorities.
Traveling abroad for surgery can be daunting. Booking Surgery removes the stress by providing:
VIP Transfers: From the airport to your hotel and the hospital.
Luxury Accommodation: 5-star hotels for your recovery period.
Personal Coordinators: Dedicated staff who speak your language.
Transparent Pricing: No hidden fees. You save up to 70% compared to private healthcare in the West.
Regardless of which surgery you choose, your success depends on your commitment to a new lifestyle.
The first few weeks involve a phased diet: clear liquids, followed by pureed foods, and eventually soft solids. Our nutritionists at Booking Surgery provide you with a detailed meal plan to ensure your new stomach heals perfectly.
Within the first year, patients typically see a dramatic transformation. Beyond the physical appearance, you will likely notice:
Increased energy levels.
Improved mobility and reduced joint pain.
Remission or improvement of sleep apnea, hypertension, and diabetes.
A massive boost in self-confidence.
Both Gastric Sleeve and Gastric Bypass are considered safe when performed by experienced surgeons in accredited hospitals. The "sleeve" is often seen as less complex because it doesn't involve intestinal rerouting, but for a patient with severe diabetes, the bypass might actually be the "safer" long-term health choice.
Rapid weight loss can lead to excess skin. This depends on your age, genetics, and starting weight. Many of our patients return to Turkey after 12-18 months for body contouring or a "Mommy Makeover" once their weight has stabilized.
While many patients bring a companion, many others travel alone. Our Booking Surgery team acts as your local family. We handle every detail, so you are never truly "alone" during your stay.
The only way to be 100% sure which procedure is right for you is through a professional consultation. Factors like your BMI, medical history (especially if you have diabetes or acid reflux), and eating habits play a huge role in the surgeon's recommendation.
At Booking Surgery, we offer a free medical assessment. You can send us your medical history and goals, and our expert surgeons will provide a personalized recommendation tailored to your body.
Whether it’s the Gastric Sleeve or the Gastric Bypass, weight loss surgery in Turkey is a powerful tool. It’s not "the easy way out"—it is a courageous step toward reclaiming your life. With the right surgical partner, the journey is safe, affordable, and life-changing.
