Gastric sleeve surgery is one of the most commonly performed procedures in obesity surgery. In this weight loss operation, a portion of the stomach is surgically removed. The stomach is reshaped into a narrow, tube-like form resembling a banana. This helps patients feel full with less food. The procedure reduces the stomach’s volume and lowers levels of the hunger hormone ghrelin, thereby supporting weight loss. In Izmir, Dr. Mehmet Deniz is one of the leading surgeons performing gastric sleeve surgery.
How is Gastric Sleeve Surgery Performed?
Gastric sleeve surgery is typically carried out using a laparoscopic technique, which involves small incisions. During the operation, about 75–80% of the stomach is removed. The remaining part takes on a tube-like shape. The procedure usually lasts around 30 minutes, and patients are generally discharged within a few days. After the operation, patients need to make significant changes to their diet and lifestyle.
What Happens Before and After Gastric Sleeve Surgery?
Before the surgery, patients undergo a comprehensive medical evaluation, and input is taken from various specialists. Factors such as body mass index (BMI), existing conditions like diabetes, and overall health status are assessed. A special pre-operative diet may be required in the weeks leading up to surgery. After the operation, patients start with a liquid diet, gradually transitioning to soft foods. To support weight loss, it’s essential to follow a nutrition plan and maintain regular physical activity. Psychological support can also be very helpful during the recovery period.
Who is a Good Candidate for Gastric Sleeve Surgery?
Gastric sleeve surgery is generally recommended for individuals with a BMI of 40 or higher. It can also be suitable for those with a BMI between 35–40 who suffer from obesity-related conditions such as type 2 diabetes, high blood pressure, sleep apnea, fatty liver, joint problems, or psychosocial issues. When evaluating eligibility, doctors consider the patient's overall health, age, previous weight loss attempts, and expectations. In İzmir, experts conduct personalized assessments to determine the best treatment plan for each individual.
Gastric Sleeve Surgery and Type 2 Diabetes
For patients with type 2 diabetes, gastric sleeve surgery can be an effective method to control blood sugar. The reduced stomach size and related hormonal changes enhance insulin sensitivity, often leading to improvement or remission of diabetes. This positions gastric sleeve not only as a weight-loss solution but also as a powerful metabolic treatment.
Obesity Surgery and the Role of Gastric Sleeve
Obesity surgery is one of the most effective ways to achieve long-term weight loss and manage obesity-related health issues. Gastric sleeve surgery is a widely preferred option because it enables patients to live a healthier life. However, long-term success depends on post-surgery support, regular follow-ups, and lifestyle changes.
How Fast is Weight Loss After Gastric Sleeve Surgery?
The rate of weight loss after gastric sleeve surgery varies depending on the patient’s age, metabolism, and commitment to diet and exercise. On average, patients can expect to lose 50–70% of their excess body weight within the first 6–12 months. Consistency, discipline, and professional guidance are key. Gastric sleeve surgery is a transformative journey for both physical and mental health. To ensure successful and sustainable results, it must be performed and monitored by an experienced medical team—and the patient’s dedication is equally important.
