All About Gastric Sleeve Surgery


Obesity is recognized as one of the major health challenges of the modern age. For many people who cannot achieve permanent weight loss despite diet and exercise programs, surgical methods are not just an aesthetic change, but a vital turning point. In this regard, Gastric Sleeve Surgery stands out as one of the most frequently performed procedures worldwide.

So, what exactly is this procedure, and how can it change your life? Here is everything you need to know about gastric sleeve surgery, one of the gold standards in bariatric surgery.

What is Gastric Sleeve Surgery?
Known in medical literature as "Sleeve Gastrectomy," Gastric Sleeve Surgery is a procedure based on reducing the volume of the stomach. Approximately 80% of the stomach is surgically removed, leaving behind a thin, banana-shaped, tube-like stomach.

The success of this procedure in weight loss relies on two fundamental mechanisms:

1.Volume Restriction: Since the stomach is smaller, a feeling of fullness occurs with much less food.
2.Hormonal Change: The removed section of the stomach, known as the fundus, is where the "hunger hormone" (Ghrelin) is secreted. When this section is removed, patients' appetite decreases significantly.

Who is it Suitable For?

Gastric sleeve surgery may not be suitable for everyone. According to international criteria, ideal candidates are:

  • Patients with a Body Mass Index (BMI) of 40 or higher.
  • Patients with a BMI between 35-40 who have obesity-related comorbidities such as diabetes, high blood pressure, or sleep apnea.
  • Those who have tried methods like diet and sports but could not achieve lasting results.
  • Those without serious psychological disorders or hormonal imbalances that would prevent surgery.
Note: For patients with severe acid reflux, alternative methods like Gastric Bypass may sometimes be more appropriate. The decision is made after a detailed evaluation with your surgeon.

How is the Procedure Performed and What Technologies are Used?
Today, gastric sleeve surgery is performed using the Laparoscopic (Closed) method. This means the patient's abdomen is not cut open; instead, the procedure is carried out through 4 or 5 tiny incisions, millimeters in size.
  • Process: Performed under general anesthesia, the procedure takes on average between 45 to 90 minutes.
  • Technology: Surgeons use high-tech automatic stapling devices called "staplers" to cut and seal the stomach simultaneously.
  • Advantage: Thanks to the closed method, post-operative pain is minimal, scarring is negligible, and the recovery process is quite fast.

Potential Risks and Complications
As with any surgical procedure, gastric sleeve surgery carries some risks. However, in experienced hands, these rates are quite low.
  • Leakage Risk: Leakage from the staple line (The most feared complication, but the rate is around 1%).
  • Bleeding or Infection: Standard surgical risks.
  • Vitamin Deficiencies: Although it is not a malabsorptive surgery, vitamin supplements may be required in the initial period due to reduced food intake.
To minimize these risks, a detailed pre-operative check-up and performing the surgery in a fully equipped hospital are critical.

Expected Results and Success Rates
The post-operative process is directly proportional to the patient's compliance with the new nutrition plan. Generally, expected results are as follows:
  • Loss of 50% of excess weight within the first 6 months.
  • Loss of 70-80% of excess weight by the end of the first year.
  • 60-80% improvement or reduction in medication use for conditions like Type 2 diabetes and hypertension.
