1 Year After Gastric Sleeve: What your diet should look like

Some surgeons will recommend you stop the following two days prior to surgery.

  • Carbonated beverages
  • Caffeine

Most surgeons will recommend you adhere to a strict clear liquid diet starting two days prior to your surgery. Clear liquids will include broth, sugar free Jell-O, sugar free popsicles, water and possibly one protein shake each day. Again, follow your surgeons instructions.

Stage : Slowly Test Pureed & Soft Solid Foods

Begins 2 days post-op to 3 weeks post-op

Stage 3 of your diet after gastric sleeve surgery will last from 1 to 7 days, depending on your surgeon.

This stage allows softer solids, but take it slow!

When youre ready to start pureed foods, blend water, skim milk, broth, or sugar-free juice with one of the following:

  • Beans
  • Maintain regular support group attendance
  • Slowly transition to more aggressive, muscle-building exercises

Stage Three Of The Gastric Sleeve Diet: Pureed Soft Foods

Its time to break out the blender. Once you are around two weeks out from your gastric sleeve surgery, you can begin incorporating pureed soft foods into your diet. The key here is to eat slowly and chew thoroughly. You may find that your tolerance for certain foods has changed, so you should take your time testing new food options.

At this stage, your food should be the consistency of a thick liquid or smooth paste. You should continue to avoid chunky or fatty foods, sugar, seasonings, starches and fibrous vegetables like broccoli and asparagus.

Stage three of the gastric sleeve diet includes pureeing the following food items with water, skim milk, broth or sugar-free juice:

  • Cooked vegetables
  • Eggs
  • Cottage cheese
  • Plain yogurt

Remember to keep drinking liquids. It is easy to become dehydrated after gastric sleeve surgery because your body is no longer getting fluids from some of the foods you used to eat, so be diligent about your liquid intake.

    • Consuming between four and six small meals a day, instead of three large ones
    • Chewing thoroughly and slowly
    • Eating high protein count foods
    • Avoiding unnecessary eating due to stress or boredom
    • Taking dietary supplements, depending on dieticians advice
    • Drinking at least 1.5 litres of water every day

    What Does Diet After Gastric Sleeve Look Like

    One of the biggest elements of a gastric sleeve procedure is the diet after gastric sleeve. In essence, gastric sleeve surgery is entirely changing the nature of a persons digestive system. To say that diet plays a role before and after gastric sleeve procedure, would be an enormous understatement.

    Before the procedure, the clinic will provide the patient with a comprehensive diet to follow to minimise surgery risk and get the digestive system ready. Following the surgery, the patient will need to stick to a strict liquid diet after gastric sleeve to help the digestive system to recover. From there, the patient will need to make some drastic lifestyle and diet choices to aid their body in losing weight and maintaining a healthy body.

    The main objectives of dieting pre gastric sleeve operation are to reduce the risk of complications and to shrink the liver. On average, those that are overweight have a greater risk of experiencing complications during surgery than those of healthy body mass index. Furthermore, if youre obese, your liver will likely have an accumulation of fat cells both in and around it making it larger than it needs to be.

    Reason For Weight Regain After Gastric Sleeve Surgery


    • The most common cause of weight regain is your stomach stretching as a result of poor diet choices, which allows you to eat more and, as a result, gain weight

    Gastric sleeve surgery works by making the patient feel full sooner while eating and by reducing the amount of hunger-causing hormones secreted by the stomach. As a result, patients lose up to 70% of their excess body weight within 18 months to 2 years.

    However, up to 3 out of 10 gastric sleeve patients gain weight after reaching their low weight . The amount varies widely by patient, ranging from only a small amount of weight to all of it .

    Can a gastric sleeve stretch?

    Yes. If you lost weight initially and then gained some back, it was most likely caused by your smaller sleeve stomach stretching out as a result of poor diet choices or lifestyle habits, including :

    • Eating or drinking the wrong things
    • Not exercising enough
    • Drinking within 30 minutes of your meals

    However, the sleeve stomach may also stretch for patients with perfect diets and eating habits.

    Gastric sleeve stretching causes weight regain by allowing patients to eat more during meals and by increasing the amount of hunger-causing hormones secreted by your stomach.

    • Have a gastric sleeve revision surgery
    • If food addiction is present, seek treatment

    Guidelines For Drinking Liquids

    • Do not drink liquids with meals. Stop drinking 30 minutes before your meals. Then wait 30 minutes after eating to drink liquids. This will:

    • Prevent the stomach from over-filling

    • Keep food from flushing out too quickly

    • Keep you feeling full longer.

  • Sip all liquids slowly. Drinking too quickly may cause nausea or vomiting.

  • Drink plenty of calorie-free liquids between meals. Plain water is best. Drink at least 6 to 8 cups each day.

  • Avoid high-calorie liquids. These add extra calories without making you feel full. For example, do not drink:

  • Regular soda pop

  • Coffee drinks

  • Kool Aid

  • Sugar-sweetened drinks

  • More than 1/2 cup diluted fruit juice in a day

  • Avoid carbonated drinks and drinking straws. These bring air into the stomach. Extra air can cause gas, bloating, and pain or pressure in the shoulder or upper chest.

  • Avoid caffeine. Caffeine may irritate your stomach and prevent your body from absorbing iron. It increases your risk of having ulcers.

  • Avoid alcohol. Alcohol is absorbed faster after weight-loss surgery and stays in your body longer. Alcohol has empty calories and may slow down weight loss or speed up weight regain. You are at risk to have problems with drinking after weight-loss surgery.
