Sleeve Gastrectomy Surgery FAQ

What Is Sleeve Gastrectomy?

Sleeve gastrectomy is a weight-loss surgery that reduces the size of the stomach. The surgeon removes a large portion of the stomach, leaving a narrow “sleeve” that limits how much food you can eat and helps you feel full sooner. This procedure can also affect hunger hormones, which may reduce appetite.

Who Is a Candidate for Sleeve Gastrectomy?

Candidates typically have obesity that has not improved with diet, exercise, or medical therapy. Your care team evaluates overall health, body mass index (BMI), and weight-related conditions such as diabetes, sleep apnea, or high blood pressure. A comprehensive assessment helps determine if surgery is appropriate.

How Should I Prepare for Surgery?

Preparation often includes:

  • Medical evaluations and lab testing
  • Nutrition counseling and pre-op diet instructions
  • Guidance on stopping smoking and alcohol use
  • Medication adjustments, especially for blood thinners or diabetes
  • Planning for time off work and post-op support

About the Sleeve Gastrectomy Procedure

Sleeve gastrectomy is usually performed laparoscopically under general anesthesia and takes about one to two hours. The surgeon removes approximately 70–80% of the stomach and staples the remaining portion into a tube shape. The intestines are not rerouted, which makes this procedure less complex than some other bariatric surgeries.

What Happens After Surgery?

After surgery, you’ll start with a liquid diet and gradually advance to soft foods and then regular textures as directed by your care team. Pain control, walking, and hydration are important early recovery goals. Follow-up visits and nutrition guidance are critical to ensure safe healing and weight loss.

How Long Does Recovery Take?

Most people return to light activities within a couple of weeks, but full recovery can take several weeks. Your timeline depends on overall health, job requirements, and how well you follow dietary and activity guidance.

What Results Can I Expect?

Weight loss varies but is often significant in the first year. Many patients see improvement in obesity-related conditions such as type 2 diabetes, high blood pressure, and sleep apnea. Long-term success depends on healthy eating, regular activity, and ongoing medical follow-up.

What Are the Potential Risks or Complications?

Risks include:

  • Bleeding or infection
  • Leaks from the staple line
  • Blood clots
  • Acid reflux or worsening heartburn
  • Nutritional deficiencies if dietary guidelines are not followed

Your surgeon will review individual risk factors and strategies to reduce complications.

When Should I Seek Medical Attention?

Call your surgeon if you have fever, severe abdominal pain, persistent vomiting, chest pain, or difficulty breathing. Prompt evaluation helps prevent serious complications.
