What Is Gastric Sleeve Surgery?
What Is Gastric Sleeve Surgery?
Gastric sleeve surgery, also known as sleeve gastrectomy, is one of the most commonly performed bariatric procedures worldwide. During this operation, approximately 75–80% of the stomach is permanently removed, leaving a narrow, tube-shaped stomach.
How Is Gastric Sleeve Surgery Performed?
The procedure is performed using minimally invasive laparoscopic techniques. Several small incisions are made in the abdominal area, allowing the surgeon to remove a large portion of the stomach with specialized surgical instruments. The surgery typically takes between 15 and 20 minutes.
How Does Gastric Sleeve Surgery Promote Weight Loss?
Weight loss after gastric sleeve surgery occurs through two primary mechanisms:
- Significant reduction in stomach volume, leading to early satiety
- Decreased production of the hunger hormone ghrelin
As a result, patients feel full with smaller portions and experience a noticeable reduction in appetite.
Who Is a Suitable Candidate for Gastric Sleeve Surgery?
Gastric sleeve surgery is generally recommended for individuals who meet specific medical criteria. Suitable candidates typically include those who:
- Have a body mass index (BMI) of 35 or higher
- Have a BMI of 30 or above with obesity-related health conditions
Final eligibility is determined after a comprehensive medical evaluation by a bariatric surgery team.
Advantages of Gastric Sleeve Surgery
Gastric sleeve surgery is considered a physiological weight loss procedure because it does not involve intestinal bypass or rerouting. This helps preserve normal digestion while supporting effective and long-term weight loss outcomes.
Expert Follow-Up and Long-Term Safety
Successful results depend not only on the surgical procedure itself but also on structured post-operative follow-up. Regular monitoring by an experienced surgeon and dietitian plays a critical role in ensuring safe, sustainable, and long-lasting weight loss.
