Which department performs gastric sleeve surgery?
Sleeve gastrectomy is usually performed by general surgeons who specialize in bariatric surgery. Bariatric surgery includes surgical procedures aimed at achieving permanent weight loss in individuals who experience health problems due to excessive weight (obesity).
Therefore, the first department a person should consult for sleeve gastrectomy is:
📍 General Surgery – Bariatric Surgery Unit.
In some hospitals, a multidisciplinary team—including specialists in endocrinology, psychiatry, dietetics, and gastroenterology—participates in the decision-making process for this surgery. Especially in university hospitals, patient evaluations are carried out based on the joint opinions of these departments.
What is Gastric Sleeve Surgery?
In medical literature, sleeve gastrectomy—commonly known as gastric sleeve surgery—is a procedure in which approximately 75–80% of the stomach is removed, significantly reducing its volume. After the surgery, the stomach takes on a tube-like shape, allowing the person to feel full with less food.
What is the goal?
✅ To reduce overall calorie intake
✅ To control appetite by decreasing the secretion of the hunger hormone (ghrelin)
✅ To prevent or treat obesity-related conditions (such as type 2 diabetes, hypertension, sleep apnea, etc.) through weight loss
Who is Suitable for Gastric Sleeve Surgery?
Not every overweight individual is a suitable candidate for sleeve gastrectomy. This surgical procedure is appropriate only for individuals who meet certain criteria:
📌 Eligibility Criteria:
Body Mass Index (BMI) of 40 or above (morbid obesity)
BMI between 35–40 accompanied by obesity-related health issues such as diabetes, hypertension, or sleep apnea
Inability to lose sufficient weight through diet and exercise
Psychological readiness for surgery and the ability to adapt to necessary lifestyle changes
In some cases, individuals with a BMI over 30 who suffer from severe obesity-related health problems may also be considered for this operation. However, this is subject to the physician’s evaluation and decision.

How Does the Gastric Sleeve Surgery Process Work?
Initial Examination and Assessment: The patient is admitted to a general surgery/bariatric surgery clinic. A licensed body mass index (BMI) assessment is performed, and the necessary assessments are conducted.
Multidisciplinary Consultation: Consultations are held with an endocrinologist, psychiatrist, dietitian, and anesthesia specialist.
Preoperative Preparation: Nutritional supplements, including some preoperative diet programs, are administered.
Surgical Procedure: The procedure typically involves laparoscopic (closed) procedures and takes approximately 1–2 hours.
Postoperative Follow-up: Regular follow-up is provided with nutrition, psychological support, and a physical activity plan.
Weight Loss Process After Gastric Sleeve Surgery
Although the weight loss process after surgery varies from person to person, rapid weight loss typically occurs within the first 6 months. By the end of the first year, patients may lose about 60–70% of their excess weight. However, during this period, the following are extremely important:
Regular follow-up with a dietitian
Psychological support
Adherence to physical activity
Consistent use of vitamin and mineral supplements
