Gastric Balloon Diet

Gastric Balloon Diet: The First 14 Days After Insertion 

It’s important that you abide by the following dietary plan so that the stomach can adapt to the inserted balloon in the best way possible. Success is only achieved by the combination of the gastric balloon, diet, and regular exercise. Eat a sufficient quantity of protein-rich foods and always eat them first. Protein is important to maintain muscle mass, and its deficiency may cause hair loss! Vary your meals, so that there is no nutrient imbalance. The intravenous fluid that you receive during the procedure may help keep you hydrated during the first 48 hours after the procedure.   

  • Day 0 (procedure day)          water (50 ml every hour, sip slowly)
  • Day 1 to 3                            clear liquids only
  • Day 4 to 7                          pureed foods only
  • Day 8 to 14                          soft foods

Day 1-3
during the first three days after the insertion of the balloon, it’s very important that you don’t take anything other than clear liquids, to allow the stomach to accept the balloon. Otherwise, you will develop abdominal cramps, nausea, and vomiting.

To avoid dehydration, you should drink a half glass of liquids every hour. It’s very important that you portion the amount over the whole hour, sipping it slowly.

Suggested Fluids:

  • Water
  • Diluted fruit juice
  • Broth or clear soups
  • Herbal tea

Avoid the following:

Carbonated drinks: since it causes abdominal bloating which leads to pain and burping.

Caffeinated drinks: since it increases the stomach acid production which can lead to gastric irritation.

Day 4-7

If you can tolerate the above, you can now start adding pureed foods. Remember to portion your intake into four small meals taken throughout the day. Refrain from consuming big meals.

Aim to eat 3-4 tablespoon-full portions of pureed foods, up to 5-times a day. Stop eating once you feel close to being full. It’s still very important that you drink a half glass of liquids per hour to avoid dehydration.

Suggested foods:

Yogurt without fruit nuggets

Low-fat Greek yogurt/Skyr


Cooked pureed vegetables (and soups)

Cooked, thin oatmeal

Milk, semi-skimmed or skimmed

Day 8-14

If you already tolerated the soft food, you can now proceed to eat soft foods. If not, continue with pureed diet for an additional couple of days.

It’s very important that you chew your foods at least 20 times, so the foods will pass the gastric balloon more readily. Always remember to eat and drink slowly because with the balloon inside your stomach you are limited with the amount of food you can consume. If you over-eat you will start feeling cramps, nausea and vomiting, and odorous burps. Eat no more than four tablespoon-full for up to five times a day. Never eat and drink at the same time. The remaining space in your stomach can only fit either food or liquids at a time. Don’t mix food with drinks. Wait for an hour after eating before you start drinking. Also, avoid drinking one hour before eating. And remember to drink a half glass of liquids every hour to avoid dehydration.

Suggested Soft Foods:

Greek yogurt (and Skyr), low fat

Cottage cheese

Toasted bread

Cooked oatmeal

Scrambled eggs

Cooked fish (and canned Tuna)

Cooked chicken

Soft-blended vegetables (mashed potatoes, well-cooked rice)

Soft fruits without skin

After 14 days: Eat Normal healthy food

You can now gradually resume eating normal regular foods, provided that you have tolerated soft foods and fluids well. Don’t eat more than 3-4 meals a day to give time for stomach emptying. Chew your food #20 before swallowing it to avoid food getting stuck. If you continue to experience nausea and vomiting, then it’s recommended that you return to soft food and liquids for a few meals to continue to supply your body with enough energy. Avoid spicy and sticky foods, and drink a sip of water shortly after a meal to rinse off the balloon. If you notice feeling nausea, vomiting, burping, abdominal cramps, heartburn or foul mouth smell, after eating your meal, you must stop eating for at least 6-8 hours, and return to soft diet till you feel better. Also, avoid drinking and eating at the same time, and wait one hour before and after eating to have a drink. And start eating smaller food amount than before till you feel better. These are signs of over-eating, and you should learn to adjust your eating habits accordingly.

Remember! People are not the same, as everyone’s stomach tolerate a different amount and type of food intake.
