    Postoperative diet guide

    After your surgery, you will need to follow a progressive diet to give your stomach time to heal. It is very important to follow each step for its duration to avoid any type of complication.

    You can take a group class before your surgery to learn more about what the progressive diet entails. At the class, you’ll also get tips to help you with the diet along with a food guide. 

    Diet overview:

    Step 1Strict liquid diet for 3 days (hospita)
    Step 2Nutritious liquid or semi-liquid diet for 14 days
    Step 3Pureed diet for 14 days
    Step 4Ground/pureed diet for 7 days
    Step 5Soft diet for 7 days
    Step 6Normal/soft diet


    The 2 main priorities when it comes to your food choices are:

    Apple and applesauce
    1. Consuming enough protein (about 60 to 80g per day)
    2. Consuming 1.5 to 2 L of liquid to prevent dehydration

    Tip: To efficiently calculate protein and other nutrients, you can use mobile apps such as MyFitnessPal. Otherwise, write down what you eat in a journal and ask your nutritionist for advice.

    You will have to eat 3 meals and 3 snacks a day to meet your needs. It is also suggested that you only drink fluids 30 minutes before or after each meal.
