Thinking about gastric sleeve surgery but not sure how it works?
You’re not alone. Many patients are curious about the procedure but feel overwhelmed by the
medical jargon. So let’s break it down in a way that’s quick, clear, and easy to understand.
How Is Gastric Sleeve Surgery Performed?
Gastric sleeve surgery—also called sleeve gastrectomy—is done laparoscopically. That means:
Minimally invasive:
Surgeons make 4 small incisions rather than one large cut.
Faster recovery:
Most patients go home within 24–48 hours and return to normal activities within a few weeks.
What Happens During the Procedure?
About 80% of your stomach is removed, leaving behind a narrow, sleeve-shaped pouch. This
reduces how much food your stomach can hold—and changes how your body regulates hunger.
How Does Gastric Sleeve Help You Lose Weight?
This procedure supports weight loss in three key ways:
You feel full faster:
Your new stomach holds less food, so you’ll feel satisfied with smaller portions.
Fewer hunger hormones:
The part of the stomach that produces ghrelin (the “hunger hormone”) is removed, which
naturally decreases appetite.
Smaller portions = fewer calories:
Eating less leads to sustainable, long-term weight loss—especially when combined with
healthy habits.
Who Is Gastric Sleeve For?
This surgery is ideal for individuals who:
- Have severe obesity (BMI ≥ 40 or BMI ≥ 35 with health conditions)
- Struggle to lose weight through diet and exercise alone
- Need to improve related health problems such as:
◦ Type 2 diabetes
◦ High blood pressure
◦ Sleep apnea
◦ Joint pain
◦ Fatty liver disease
Who Is It Not Recommended For?
Patients with severe acid reflux or GERD
Gastric sleeve surgery can worsen acid reflux. For these patients, gastric bypass may be a
better surgical option.
Final Thoughts
Gastric sleeve surgery is a safe, effective, and minimally invasive option for long-term weight
loss—but it’s not one-size-fits-all. Understanding how the procedure works is the first step
toward making the right decision for your health.
