Sleeve Gastrectomy
What is Sleeve Gastrectomy?
Sleeve Gastrectomy (often called the Gastric Sleeve) is a permanent bariatric surgery that removes approximately 70–80% of the stomach, leaving behind a narrow, banana-shaped “sleeve.” This procedure limits the amount of food that can be consumed (restriction) and, crucially, removes the stomach portion that produces Ghrelin (the “hunger hormone”). The combined effect supports significant and sustained weight loss and helps patients achieve long-term weight management by lowering hunger levels.
Key Features of the Procedure
- Performed Laparoscopically or Robotically – ensuring minimal scarring, shorter hospital stays, and faster recovery
- Preserves Digestive Tract Anatomy – no rerouting of intestines
- Lower Risk of Nutrient Deficiency compared to malabsorptive surgeries
- Reduces Hunger & Enhances Satiety
Who is it recommended for?
1. individuals with morbid obesity (BMI ≥ 40) or BMI ≥ 35 with comorbidities like: Type 2 Diabetes, Hypertension, PCOS, Sleep Apnea
2. Ideal for younger patients and as a first-stage surgery for individuals with very high BMI (60+)
3. Not suitable for those with:
- Severe GERD (acid reflux)
- Large hiatal hernias
Nutrition Care Plan for Pre- and Post-Bariatric Procedure
Before Surgery:
Follow a 7-day liquid diet to help shrink your liver and prepare your body for a safer procedure.
After Surgery :
You’ll follow a structured diet plan to support healing and healthy weight loss:
- Week 1-2: Clear and full liquids
- Weeks 3-4: Soft or pureed foods
- Week 4 and beyond: Gradual reintroduction of healthy solid foods
Foods to Avoid (especially early on):
- Sugary foods and drinks
- Carbonated beverages
- Fried or greasy foods
- Tough meats and foods with skins
Following this plan helps your stomach heal properly and sets the foundation for long-term success.
Is Sleeve Gastrectomy reversible?
No. Since Sleeve Gastrectomy involves the permanent removal of a large portion of the stomach, it is not reversible. This is a key difference when comparing it to procedures like the Gastric Balloon or Gastric Banding. Patients seeking this bariatric surgery in Mumbai must be prepared for this lifelong change.
How quickly will I lose weight after a Gastric Sleeve?
Weight loss is generally rapid in the first 6 to 12 months. Most patients lose 50% to 70% of their excess body weight within the first 18 months. The continuous feeling of reduced hunger due to the removal of the ghrelin-producing cells significantly aids in maintaining a lower calorie intake.
Does Sleeve Gastrectomy cure Type 2 Diabetes?
While the Gastric Sleeve is highly effective, it often results in the remission of Type 2 Diabetes and other metabolic conditions, such as high blood pressure and sleep apnea, often occurring even before major weight loss begins. This is due to the hormonal changes triggered by the procedure.
What are the risks of long-term acid reflux after a Gastric Sleeve?
A small percentage of patients may experience or develop acid reflux (GERD) after a Sleeve Gastrectomy. If reflux is a major concern, your sleeve surgeon in Mumbai may discuss alternative procedures, like the Roux-en-Y Gastric Bypass, which is often better for managing pre-existing severe reflux.
