Gastric sleeve surgery, or sleeve gastrectomy, is a popular weight loss procedure that significantly reduces the size of the stomach. This surgery helps patients lose weight by limiting food intake and reducing hunger. However, to ensure the success of the surgery and promote healing, patients must adhere to a specific post-op diet. This diet progresses through several stages, each designed to help the body adjust to the new stomach size and support a gradual return to regular eating habits. Here’s a detailed look at each stage of the post-op gastric sleeve surgery diet.

- Sugar-free gelatin
- Decaffeinated tea and coffee (without sugar)
- Sugar-free popsicles
Tips:
- Sip slowly to avoid nausea and vomiting.
- Aim to drink at least 48-64 ounces of fluids daily to stay hydrated.
- Avoid carbonated and caffeinated beverages as they can irritate the stomach.
Stage 2: Full Liquid Diet (Weeks 2-3)
Purpose: This stage introduces more nutritious liquids to provide additional nutrients while still being gentle on the stomach.
Allowed Foods:
- Protein shakes (low-sugar, high-protein)
- Skim or low-fat milk
- Strained cream soups (without chunks)
- Sugar-free, non-fat yogurt
- Smoothies made with protein powder and non-fat milk or water
Tips:
- Continue to prioritize hydration alongside nutritional intake.
- Incorporate high-protein liquids to support healing and maintain muscle mass.
- Drink slowly and stop if you feel full to avoid overloading your stomach.
Stage 3: Pureed Diet (Weeks 4-5)

Purpose: This stage aims to introduce more texture and variety into the diet while still being gentle on the stomach.
Allowed Foods:
- Ground or finely chopped meats
- Soft fruits (bananas, melons)
- Cooked vegetables (without skins)
- Soft cereals (oatmeal, cream of wheat)
- Low-fat cheese
Tips:
- Chew food thoroughly to aid digestion and prevent discomfort.

FAQs About Diet After Gastric Sleeve Surgery
- What should I expect during the initial stages of the post-op diet after gastric sleeve surgery?
Answer:
In the initial stages after gastric sleeve surgery, the diet is carefully structured to promote healing and help your body adjust to the new stomach size. The first stage consists of a clear liquid diet for about a week, which includes water, broth, sugar-free gelatin, and decaffeinated tea. This is followed by a full liquid diet for another week or two, which introduces protein shakes, skim milk, and strained soups. Gradually, you will progress to pureed foods and then to soft foods before finally reintroducing regular, solid foods over the course of several weeks.
- Why is it important to avoid high-sugar and high-fat foods after gastric sleeve surgery?
Answer:
High-sugar and high-fat foods can cause several complications after gastric sleeve surgery. High-sugar foods can lead to dumping syndrome, a condition where food moves too quickly from the stomach to the intestines, causing symptoms like nausea, vomiting, dizziness, and diarrhea. High-fat foods are harder to digest and can cause gastrointestinal discomfort, including bloating, gas, and diarrhea. Additionally, both high-sugar and high-fat foods are calorie-dense and can hinder weight loss efforts, potentially leading to weight regain.
- How can I ensure I am getting enough protein in my diet after gastric sleeve surgery?
Answer:
Getting enough protein is crucial for healing and maintaining muscle mass after gastric sleeve surgery. Start with protein shakes and low-fat dairy products during the full liquid stage. As you progress to pureed and soft foods, incorporate sources like pureed meats, scrambled eggs, low-fat cottage cheese, and Greek yogurt. When you reach the regular diet stage, focus on lean proteins such as chicken, turkey, fish, and legumes. Aim for 60-80 grams of protein per day, and consider protein supplements if needed, following your healthcare provider’s recommendations.
