A Complete Guide to Understanding Gastric Sleeve Surgery

Gastric Sleeve Surgery


In this comprehensive guide, we will explore gastric sleeve surgery, from its definition and candidacy criteria to the procedure itself, recovery, and long-term outcomes.

What Is Gastric Sleeve Surgery?

Gastric sleeve surgery, also known as sleeve gastrectomy or vertical sleeve gastrectomy (VSG), is a surgical weight loss procedure designed to reduce the size of the stomach. During the surgery, the surgeon removes a significant portion of the stomach, leaving a smaller, banana-shaped “sleeve” or pouch. This reduction in stomach size restricts the amount of food a person can consume, leading to reduced calorie intake and, consequently, weight loss.


Who Is a Candidate for Gastric Sleeve Surgery?

Not everyone is a candidate for gastric sleeve surgery. Ideal candidates typically meet certain criteria, including

  • Having a body mass index (BMI) of 40 or higher (or a BMI of 35-39.9 with obesity-related health issues).
  • Repeated unsuccessful attempts at weight loss through diet and exercise.
  • A commitment to lifelong dietary and lifestyle changes.
  • No history of alcohol or drug addiction.
  • The absence of certain medical conditions that might increase surgical risks.
  • It’s crucial to consult with a qualified bariatric surgeon to determine if gastric sleeve surgery is the right option for you.
