Gastric Sleeve surgery in Turkey

Gastric sleeve surgery (Sleeve Gastrectomy) is a weight-loss operation in which the surgeon permanently reduces the size of the stomach. During the procedure, approximately 75–80% of the stomach is removed, leaving behind a narrow, tube-shaped stomach (the “sleeve”).
Because a large portion of the stomach is removed, gastric sleeve surgery is irreversible.

Unlike gastric bypass, where no part of the stomach is removed, gastric sleeve surgery physically reduces stomach volume and decreases hunger hormones, helping patients feel full sooner and eat less.

Why Is Gastric Sleeve Surgery Performed?

Gastric sleeve surgery is recommended for individuals with severe obesity who have not achieved sustainable weight loss through diet and physical activity. Severe obesity is associated with serious health risks, and reducing excess weight can be life-saving.

Obesity may lead to:

• Type 2 diabetes

• High blood pressure

• Heart disease

• Joint problems

• Sleep apnea and other metabolic conditions

For these patients, gastric sleeve surgery can be an effective long-term solution.

Decision for Surgery

The decision to proceed with gastric sleeve surgery is made by a bariatric surgeon after:

• Reviewing medical tests

• Assessing surgical risks

• Evaluating the patient’s health history and lifestyle

Only patients who are medically suitable and psychologically prepared are recommended for surgery.

Who Is a Candidate for Gastric Sleeve Surgery in Turkey?

Gastric sleeve surgery may be suitable for patients who meet one or more of the following criteria:

✔ BMI Over 40

Patients with a Body Mass Index (BMI) above 40 (morbid obesity) are considered ideal candidates.

✔ BMI 33–39.5 With Medical Conditions

Patients with a BMI between 33 and 39.5 who also suffer from type 2 diabetes or high blood pressure may qualify.

✔ Excess Weight of 45 kg or More

Individuals who are 45 kg or more above their ideal weight are also good candidates.

✔ No Drug or Alcohol Addiction

Patients must not have active drug or alcohol addiction and should be mentally and emotionally stable.

✔ Psychogenic (Neurotic) Obesity

If obesity is related to psychological factors and eating behavior, surgery may still be considered after proper evaluation.

⚠️ In selected cases, patients with BMI over 32 may undergo gastric sleeve surgery at the discretion of medical specialists following detailed assessment.

Gastric Sleeve Surgery Approaches

1. Step-by-Step (Staged) Approach

This method is used for patients with very high BMI or those with heart or lung problems who cannot tolerate long anesthesia. Surgery is completed in several stages for safety.

2. Two-Step Procedure (Conversion from Bypass to Sleeve)

Sometimes, during a planned bypass surgery, the surgeon may switch to a sleeve approach if:

• The liver is too large

• Extensive scar tissue is present

This ensures a safer and shorter operation.

Surgical Technique

Gastric sleeve surgery is performed using laparoscopic (minimally invasive) techniques. A thin tube with a camera and surgical instruments is inserted through small incisions, minimizing pain, scarring, and recovery time.

Who Is NOT Suitable for Gastric Sleeve Surgery?

Gastric sleeve surgery may not be recommended for:

• Patients with severe gastric reflux (GERD)

• Individuals with uncontrolled eating habits, such as constant snacking throughout the day

In such cases, the stomach may gradually stretch again, leading to weight regain.
