What Is Gastric Sleeve Surgery?

Gastric sleeve surgery (also called sleeve gastrectomy) removes a portion of the stomach, creating a smaller, sleeve‑shaped stomach.
This helps reduce appetite and supports long‑term weight loss.

People choose the gastric sleeve because it:

• limits how much food the stomach can hold
• reduces hunger hormones
• supports steady weight loss over time
• does not involve rerouting the intestines

It is a permanent procedure.

How the Procedure Works

During the surgery:

• the stomach is reshaped into a narrow tube
• about 70–80% of the stomach is removed
• digestion continues normally
• no foreign devices are implanted

The smaller stomach helps you feel full with less food, and many people experience reduced hunger.

Who the Gastric Sleeve Is For

Doctors may recommend the gastric sleeve for people who:

• have a high BMI
• have struggled with weight for many years
• have weight‑related health conditions
• have tried other methods without long‑term success

Only a licensed medical professional can determine eligibility.

Benefits of Gastric Sleeve Surgery

People often choose the gastric sleeve because it may:

• support significant weight loss
• reduce appetite
• improve energy levels
• help with conditions like high blood pressure or diabetes
• require fewer long‑term restrictions than other surgeries

Results vary from person to person.

Possible Risks and Considerations

Like any surgery, the gastric sleeve has risks. These may include:

• nausea or vomiting
• acid reflux
• nutrient deficiencies
• surgical complications
• changes in appetite or digestion

A healthcare provider can explain risks based on your personal health.

Recovery Overview

Recovery experiences vary, but many people:

• stay in the hospital for 1–2 days
• follow a liquid diet at first
• slowly reintroduce soft foods
• return to normal activities within a few weeks
• see weight changes over several months

Long‑term success depends on healthy habits and follow‑up care.
