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.
