A Permanent, Proven Solution for Obesity
Gastric sleeve surgery, also known as a sleeve gastrectomy, is one of the most effective and widely performed procedures in the field of bariatric surgery (obesity surgery). At Dr. Cinik Hospital in Istanbul, this minimally invasive weight loss surgery is offered as part of a personalized treatment plan for patients suffering from obesity and related health conditions.
If you are considering gastric sleeve surgery in Turkey, our internationally accredited facility provides advanced care, full coordination for international patients, and long-term remote follow-up to support your transformation.
During gastric sleeve surgery, about 75–80% of the stomach is removed; what is left is a narrow, tube-shaped “sleeve.” This smaller stomach has little room for food; also, production of the hunger hormone ghrelin significantly decreases, which reduces hunger.
Unlike gastric bypass, this procedure does not alter the intestines or nutrient absorption, making gastric sleeve a simpler yet highly effective option for long-term weight loss.
This procedure is ideal for patients who:
A psychological and nutritional evaluation is an inseparable part of our preoperative protocol to ensure that every patient is both medically and mentally prepared.
Dr. Cinik Hospital offers international patients:
Here’s what to expect if you choose to have gastric sleeve surgery in Istanbul:
Before traveling, you’ll be asked to submit two specific lab results:
These tests will help assess your metabolic status and diabetes control, which are essential for surgical planning.
Once you arrive, you will be welcomed by our patient coordination team. Hospitalization begins the night before surgery to allow for pre-operative preparation.
You’ll undergo:
Patients typically lose 60–70% of their excess weight within the first 12-18 months. You’ll need to follow a strict dietary plan, beginning with liquids, then moving to soft foods, and eventually healthy solids.
Many coexisting conditions (e.g., diabetes, hypertension, joint pain) improve or go into remission following surgery.
As a rule, gastric sleeve surgery is safe. However, like with any surgical procedure, there might be potential risks, e.g.:
At Dr. Cinik Hospital, we take every measure to minimize risks with detailed preparation, expert surgical technique, and dedicated post-operative care.
Gastric sleeve surgery is not a quick fix: it’s a lifestyle-altering commitment. So, as a patient, you MUST:
After massive weight loss, some patients may have excess skin or changes in body shape. Dr. Cinik’s team also offers aesthetic surgery options like tummy tucks, arm lifts, or thigh lifts—available once your weight has stabilized (usually after 12-18 months).
How is the gastric sleeve different from the gastric bypass?
While both promote weight loss, the sleeve only reduces the stomach size, whereas bypass also alters the intestines to limit calorie absorption. The sleeve is less complex and doesn’t carry the same malabsorption risks.
Will I feel hungry after the procedure?
Not in the same way. The part of the stomach that produces most of the hunger hormone (ghrelin) is removed, which significantly reduces appetite.
Can the stomach stretch back to its original size?
It won’t return to its original volume, but if you don’t follow the post-operative diet, the sleeve can stretch over time. Portion control is key to long-term success.
Do I need to lose weight before surgery?
In some cases, yes. Your surgeon may ask you to follow a short-term diet to reduce liver size and improve surgical safety.
Will I have scars?
Only small scars remain from the laparoscopic incisions (typically 4–5 very small marks). They will fade significantly over time.
Can this procedure help with diabetes?
In many cases, yes. Gastric sleeve surgery often leads to dramatic improvement or remission of type 2 diabetes, especially if the condition is not advanced.
This older method uses a band and staples to create a small stomach pouch. It’s less commonly performed today but remains an option. The obesity surgery cost for Vertical Banded Gastroplasty can vary widely.
