What is Gastric Sleeve Surgery?
Gastric sleeve surgery, also called sleeve gastrectomy, is a bariatric procedure in which a large portion of the stomach is removed, leaving a small, tube-shaped stomach. This reduces the amount of food you can eat at one time and helps regulate hunger hormones (ghrelin), which decreases appetite.
The outcome is effective and sustainable weight loss, with patients feeling full faster and consuming fewer calories.
Why is Post-Gastric Sleeve Nutrition Important?
Post-Gastric Sleeve Diet Stages
After surgery, your diet progresses through four main stages. Each stage is designed to give your stomach time to heal while ensuring you receive adequate nutrition.
1. Liquid Phase (0–2 Weeks)
During the first two weeks, consume clear liquids and protein-rich beverages:
Clear broths and soups
Lactose-free milk or plant-based milk
Protein shakes
Smooth, seedless soups
2. Pureed Phase (2–4 Weeks)
Transition to soft, pureed foods that are easy to digest while focusing on protein intake:
Mashed vegetables
Pureed lean meats or fish
Low-fat yogurt or cottage cheese
Soft scrambled eggs
3. Soft Solid Phase (1–2 Months)
Start introducing soft solid foods gradually:
Well-cooked vegetables
Soft fruits without skin
Tender meats, eggs, or fish
Small portions of whole grains
4. Solid Foods Phase (After 2 Months)
Gradually return to a normal diet, while maintaining:
Portion control to avoid overeating
Balanced meals with protein, vegetables, and healthy fats
Avoidance of hard-to-digest or highly processed foods
Tips for a Successful Gastric Sleeve Diet
Eat slowly and chew thoroughly
Stay hydrated: Drink 1.5–2 liters of water daily, but avoid drinking during meals
Prioritize protein in every meal to preserve muscle mass
Avoid sugary, fried, and carbonated foods to prevent discomfort
Take recommended vitamins and minerals to avoid deficiencies
One-Month and Two-Month Guidelines
1 Month After Surgery: Soft foods like boiled and mashed vegetables, eggs, and yogurt can be introduced.
2 Months After Surgery: Return to normal foods, but keep portions small and avoid difficult-to-digest items.
Long-Term Benefits of Following a Post-Gastric Sleeve Diet
Turkey has become one of the top destinations for gastric sleeve surgery due to its combination of high-quality care and affordable prices. On average, the gastric sleeve in Turkey price ranges from $2,000 to $4,500, depending on the hospital, surgeon’s experience, and post-operative care included. Despite the lower cost compared to Europe or the USA, patients benefit from modern medical facilities, experienced bariatric surgeons, and comprehensive aftercare programs, making Turkey a preferred choice for international patients seeking safe and effective weight loss surgery.
