Gastric balloon diet

Gastric Balloon Diet: The First 7 Days After Insertion 

It is extremely important that you abide by the following dietary plan, so that the stomach can adapt to the newly inserted stomach balloon in the best way possible. Be aware that this diet regime is a general guideline, and that it is highly individual how fast people adapt to the gastric balloon. The amount and types of foods that are tolerated with the balloon also differ greatly between people. If you at any stage during this adaptation period feel that you are progressing too quickly, simply continue with the food you can currently tolerate for an additional day or two, and then progress accordingly. Listen to your body and your stomach, and carefully figure out what works for you!


The day of your stomach balloon insertion you must stick to drinking only water or slowly eating small popsicles or ice cubes. It is of vital importance that you limit yourself to a maximum of 50 ml per hour – not in one gulp, but by taking small sips often. The intravenous fluid that you receive following the insertion of the balloon will help keep you hydrated during the first 24 hours after the procedure. Any dairy and pulp free popsicle or frozen ice is suitable, and this will provide you with a refreshing and cold sensation without filling up above the gastric balloon.


To allow your stomach to accept the balloon, you should only consume clear liquids on the day following the procedure. Consumption of anything else may cause abdominal cramps, nausea and vomiting. To avoid dehydration, continue to drink 50 ml of liquids every hour. It is very important that you spread the amount over the whole hour, sipping it slowly.

Clear liquids

Water – add citrus fruit or fresh herbs for variation

Diluted fruit juice, without pulp

Squash juice/diluted

Broth or clear soups

Herbal tea

Protein water – with no milk

Avoid carbonated and caffeinated drinks as these can cause abdominal bloating and increased stomach acidity production which can lead to pain, burping and gastric irritation.

Day 2 + 3 - FULL LIQUIDS

If the above diet is tolerated, you can now introduce thicker fluids with pulp and pureed/blended foods. Start by eating only 2-3 tablespoons of foods, up to 5 times a day. Only eat until you no longer feel hungry – not full/too full. Continue to drink 50 ml of liquids per hour to avoid dehydration.

Full liquids

Yogurt without pieces of fruit


Pureed cooked vegetables and soups

Fruit puree

Cooked, soft oatmeal


Protein shakes

Sugar free jelly


If you can tolerate the soft diet well, you can now proceed to more solid foods that requires more chewing and digestion. If you experience discomfort, or feel that you are progressing too quickly, continue with fluid diet for an additional couple of days.   

It is very important that you chew your food thoroughly (at least 20 times) until it becomes a viscous mass that will readily pass the gastric balloon. You must also allow time for the food to leave the stomach before eating again. Always remember to eat and drink slowly and pay attention to how your stomach reacts. There is a huge difference between feeling not hungry/satisfied and full or beyond full. Over-eating will result in stomach cramps, nausea, vomiting and odorous burps.

Do not eat and drink the same time. The remaining space in your stomach can only fit either food or liquids at a time. Stop drinking an hour before eating, and similarly, avoid drinking the first hour after a meal. Liquids can accumulate over the balloon and cause reflux, vomiting and discomfort.

However, you must drink to remain hydrated. Continue to spread your liquids out by frequently taking small sips between meals. If you at this point can tolerate 50 ml without difficulties, and feel dehydrated or thirsty, you can slowly increase your intake to 70 and then 100 ml of fluid per hour.

Soft foods

Cooked vegetables

Cottage cheese and low-fat soft cheeses

Toasted bread

Cooked oatmeal

Scrambled eggs

Cooked/blended meat, chicken, fish

Canned tuna, mackerel or salmon

Baked beans

Soft-blended vegetables (mashed potatoes)

Soft fruits without skin



Day 5 onwards - PROGRESS TO SOLID

When your stomach allows it, you should be able to eat a completely normal, healthy and varied diet with normal foods. The important thing is the amount of food you eat, and that you chew this sufficiently. There are, however, certain foods that tend to be poorly tolerated by some people as they are difficult to digest or can stick to the balloon. These foods include red meat, dark rye bread, pasta, rice, white bread and buns, fatty foods, caffeine and fizzy drinks. You must constantly pay attention to what your stomach is telling you and learn to notice when you are satisfied and when you are full/overly full.

Spend time on your meals and eat slowly. Continue to chew your food thoroughly before swallowing it, to avoid food getting stuck. If you swallow the food without properly chewing it, it can remain in the stomach for 10-14 days and cause discomfort and pain.

If you continue to experience nausea, bad breath, burps, abdominal cramps, vomiting and reflux, we recommend you stop eating and drinking for 8-12 hours. After this, return to soft food and liquids for 1-2 days to allow your stomach to rest and re-settle a bit. These are signs of eating too fast, over-eating or eating foods your stomach cannot tolerate at this point.

It takes time to get used to the stomach balloon, and you have to figure out yourself what works for you. What you are able to tolerate and not, can also change during the course of the balloon, so difficult foods early on with the gastric balloon might be well tolerated later on.

Success is best achieved by the combination of the gastric balloon, appropriate diet and regular exercise. Eat a varied, healthy diet with foods you enjoy. Start with smaller portions than the suggestions below and increase as tolerated. It is important, that you get enough nutrients and energy, but do not over-eat as it’s best not to “test” the balloon – simply stop when you’re not hungry.
