What is Sleeve Gastrectomy?
Sleeve gastrectomy, also called gastric sleeve surgery, is an FDA-approved, minimally invasive bariatric procedure. During this surgery, a large portion of the stomach is removed, leaving behind a smaller, sleeve-shaped stomach pouch.
This new pouch:
- Significantly reduces food capacity
- Helps you feel full with smaller portions
- Decreases appetite by lowering hunger hormone (ghrelin) production
- Supports steady, long-term weight loss
Unlike other weight loss procedures, sleeve gastrectomy does not involve rerouting the intestines, making it a simpler yet highly effective option for many patients.
Benefits of Sleeve Gastrectomy
Choosing sleeve gastrectomy comes with important advantages:
- Minimally invasive laparoscopic procedure
- High success rate with long-term weight loss
- Improves or resolves obesity-related conditions (diabetes, sleep apnea, hypertension)
- No implanted devices
- No rerouting of the intestines (unlike gastric bypass)
- Reduced hunger due to decreased ghrelin production
For many patients, these benefits make sleeve gastrectomy a powerful tool for lasting weight management.
What to Expect During the Sleeve Gastrectomy Procedure
At Houston Surgical Weight Loss, Dr. Wadiwala uses advanced laparoscopic techniques to ensure minimal pain, faster healing, and reduced scarring.
Step-by-step process:
- Small incisions are made in your abdomen.
- Surgical tools and a laparoscope are inserted.
- Approximately 70–80% of the stomach is removed.
- The remaining stomach is shaped into a narrow sleeve or tube.
This smaller stomach pouch reduces food intake and naturally lowers appetite, helping you achieve weight loss without rerouting your digestive tract.
Recovery After Sleeve Gastrectomy
Because the surgery is minimally invasive, most patients recover quickly and safely.
What to expect:
- Most patients go home on the same day.
- Small incisions heal faster, minimizing downtime
- Return to light activities within 1–2 weeks
- Resume normal routines in 2–4 weeks
- Long-term weight loss begins within the first few months
- Special dietary phases (liquid → pureed → soft → regular foods)
- Lifelong vitamin supplementation is required to avoid deficiencies
Patients typically experience less pain, fewer complications, and a smoother recovery compared to more invasive procedures.
Is Sleeve Gastrectomy Right for You?
You may be a candidate for sleeve gastrectomy if you:
- Have a BMI of 30 or higher with comorbidities
- Have a BMI of 35 or higher without comorbidities
- Have not achieved significant weight loss with diet and exercise alone
- Are committed to long-term lifestyle changes
- Want a permanent solution without implants or intestinal rerouting
During your consultation, Dr. Wadiwala will carefully review your medical history and weight loss goals to determine if sleeve gastrectomy is your best option.
