What is Gastric Sleeve Surgery?

Gastric sleeve surgery, also known as sleeve gastrectomy, is a popular bariatric procedure designed to help individuals achieve significant weight loss. This surgery involves removing a portion of the stomach, creating a smaller, tube-shaped stomach or 'sleeve.' By reducing the size of the stomach, patients experience decreased appetite and consume smaller portions, leading to sustained weight loss.

In Switzerland, gastric sleeve surgery is performed under stringent medical standards, ensuring maximum safety and precision. Swiss clinics prioritize the health and well-being of each patient, utilizing advanced surgical techniques in state-of-the-art facilities.

How Gastric Sleeve Surgery Works

During the procedure, approximately 80% of the stomach is surgically removed, leaving behind a narrow 'sleeve.' This smaller stomach restricts the amount of food that can be consumed and significantly reduces hunger hormones like ghrelin, promoting long-term weight management. Unlike gastric banding, this procedure is permanent and does not involve the implantation of foreign objects.

Who Is a Good Candidate

Ideal candidates for gastric sleeve surgery are individuals with a BMI over 35 who have struggled with weight loss through traditional methods such as diet and exercise. Patients with obesity-related health conditions like type 2 diabetes or hypertension may benefit greatly from this procedure. A consultation with a Swiss bariatric surgeon is essential to determine eligibility.

The Procedure

1. Pre-surgery Preparation: Patients undergo thorough evaluations, including blood tests and imaging, to ensure they are fit for surgery.
2. Anesthesia: The procedure is performed under general anesthesia.
3. Laparoscopic Surgery: Using minimally invasive techniques, the surgeon removes approximately 80% of the stomach.
4. Closure: The remaining stomach is closed with sutures, creating the 'sleeve' shape.
5. Recovery: Patients typically stay in the hospital for 2-3 nights for monitoring.
