SLEEVE GASTRECTOMY

One of the Most Effective and Preferred Methods in Obesity Surgery

How Sleeve Gastrectomy Works

Sleeve gastrectomy is a surgical procedure that induces weight loss by restricting food intake. Typically performed laparoscopically, the surgeon removes approximately 75% of the stomach, transforming it into a smaller tube or banana shape. Although initially designed as the first stage of a two-step procedure for super-obese or high-risk patients, sleeve gastrectomy is now commonly used to promote weight loss in individuals with a BMI over 40 and has proven effective in achieving successful weight reduction.

Statistically, reported weight loss for this procedure exceeds 60% of excess weight. Better results are achieved with adherence to dietary and behavioral guidelines before and after surgery. With the guidance of a bariatric dietitian and the healthy meal options recommended during check-ups, patients can enjoy and maintain effective weight loss through regular exercise and good nutrition habits.

Advantages of Sleeve Gastrectomy

In sleeve gastrectomy, there is no implanted foreign body, as in adjustable gastric banding, nor is there complex intestinal restructuring as in gastric bypass. After a reasonable recovery period, most patients find they can comfortably eat a wide variety of foods, including meat and fibrous vegetables, although in reduced portions due to the smaller stomach volume. However, unlike adjustable gastric banding or gastric bypass, sleeve gastrectomy is a permanent procedure and cannot be reversed. Removing part of the stomach lowers the level of a hormone called ghrelin, often referred to as the “hunger hormone.” Consequently, many patients feel less hungry after the procedure. Ghrelin also plays a role in blood sugar metabolism, so patients with type II diabetes often experience a significant reduction in their need for diabetes medications (particularly oral pills) immediately after sleeve gastrectomy.

Disadvantages of Sleeve Gastrectomy

As with some other surgical procedures, sleeve gastrectomy is irreversible. The early-stage complication rate for this surgery is similar to that of traditional gastric bypass. Patients are at risk of nutrient deficiencies in the long term, making close follow-up essential after surgery.

How is Sleeve Gastrectomy Performed?

In this surgery, approximately 75-80% of the stomach is removed. The goal is to significantly reduce the stomach’s capacity to prevent excessive food intake in patients with obesity. The operation is performed entirely using a closed (laparoscopic) method, with cameras and instruments inserted through several small cannulas, called trocars, ranging from 5mm to 15mm in the abdominal area.

Who is Eligible for Sleeve Gastrectomy?

Eligibility for sleeve gastrectomy is determined based on the Body Mass Index (BMI) calculation. If the height-to-weight ratio (BMI) is 35 or above and obesity-related health conditions are present, surgery is recommended. Metabolic surgery may also be suggested for patients with uncontrolled diabetes and a BMI over 30. No additional eligibility criteria apply for patients with a BMI over 40. If the patient has other conditions that may increase surgical risk, these need to be treated first.

Recovery After Sleeve Gastrectomy

After three days of observation in the hospital, patients are discharged and can generally return to their normal lives within 10-15 days with home care.

Post-Surgery Nutrition for Sleeve Gastrectomy

Post-surgery, there are several dietary phases: clear liquids, followed by thicker liquids, then pureed foods, and finally a healthy, lifelong diet. This dietary progression may vary depending on the type of surgery performed.
