Weight loss surgery has revolutionized how we approach obesity and its related health conditions. One of the most popular surgical options is gastrectomy, a procedure where a part of the stomach is removed to limit food intake and aid in weight reduction. Among the different types, Vertical Sleeve Gastrectomy (VSG) stands out for its effectiveness, safety, and relatively simple procedure.
“As a surgeon, I’ve witnessed firsthand how sleeve gastrectomy transforms lives—not just physically, but emotionally. It’s not just about eating less, it’s about regaining control and confidence,” shares Dr. Harsh Sheth.

Curious about what happens during the procedure? Let’s walk you through the surgery step by step.
What happens to the stomach during a sleeve gastrectomy?
Vertical sleeve gastrectomy is a restrictive weight loss surgery that alters the size and structure of your stomach. Here’s how:
- Stomach Reduction: About 75-80% of the stomach is removed. The remaining portion is a slender, tube-like “sleeve.”
- Shape and Capacity: The new stomach can contain much less food—about 100 to 150 ml—and make you feel full sooner and longer.
- Hormonal Impact: The part of the stomach responsible for producing ghrelin (the “hunger hormone”) is eliminated, which reduces appetite quite a lot.
“Patients find it amazing how hunger and cravings are reduced after surgery. It’s not only mechanical; it’s hormonal, also,” says Dr. Sheth.
Now that you understand what happens during surgery, let’s explore what comes after.
What should I eat and avoid after vertical sleeve surgery?
Phase 1: Clear Liquids (First few days)
- Water, broth, unsweetened clear juices
- Avoid caffeine, carbonated drinks, and sugar
Phase 2: Full Liquids (1-2 weeks post-op)
- Protein shakes, milk, smooth soups, yogurt
- Continue avoiding sugary or fizzy beverages
Phase 3: Pureed Foods (Weeks 3-4)
- Blended lean proteins, vegetables, fruits
- Small, frequent meals
Phase 4: Soft Foods (Week 5)
- Eggs, cooked veggies, fish, tender meats
- Introduce one food at a time to check tolerance
Phase 5: Regular Foods (After 6-8 weeks)

- Avoid fried, high-sugar, and processed foods
Some other dietary recommendations are:
- Eat slowly and chew well
- Stop eating when feeling full to avoid overeating
- Drink plenty of fluids but not 30 minutes prior to and following meals
“Nutrition is also a major factor after surgery. Properly planned eating is your ultimate long-term weight loss buddy,” advises Dr. Sheth.
