What is the gastric balloon?
The gastric balloon is a spherical device that is inserted into the stomach and then filled with saline (salt water). The average fill volume is between 450-600ml but this can vary from person to person. When filled it is about the size of a grapefruit and occupies about 60% of the space in your stomach. This leaves less room for food, helping you to reduce your portion size and keep you feeling satisfied for longer.
How the balloon works in detail
Swallowable balloons
You are taken into the radiology suite of the hospital where the doctor, this is usually a gastroenterologist or surgeon, will ask you to be seated then pass you the capsule to swallow. You will place the capsule, attached to a long thin tube, at the back of your tongue and with a glass of water, swallow the capsule until the doctor identifies it has reached the stomach. An Xray will be taken to confirm it is in the correct place.
The doctor will gradually fill the balloon with 550ml saline (saltwater) and a further xray taken to check the position before the tube is pulled back out of the mouth.
As you have not been sedated you can drive yourself home and after 10 minutes to check you are feeling well, you will be free to leave the clinic. The implantation process takes 15-20 minutes and you will be in clinic for approximately 40 minutes.
You will have received a supply of medications to minimise sickness and to protect the wall of your stomach while the balloon is in place.
During the period that the balloon is in place you need to focus on making changes to your diet and exercise habits so that you maximise your weight loss and adopt habits that can help sustain that after the balloon is removed.
At approximately 16 weeks a self-release valve on the balloon will open and the harmless fluid will empty into the stomach. The thin balloon casing will pass through your system and exit, usually in a bowel movement. There is no need to return to the clinic for a repeat appointment.
Endoscopic balloons
You are taken into the endoscopy suite of the hospital where the doctor, this is usually a gastroenterologist or surgeon, will sedate you for your comfort then inspect the inside of your stomach using a gastroscope. This is to make sure that the stomach wall is healthy and it is safe to proceed.
Once this has been done, the empty balloon is fed into the stomach and filled with water. Once full the water tube is pulled back, separating from the balloon and forming a tight seal. The implantation process takes 15-20 minutes but you will be in hospital for 3-4hours.
You will be kept in the recovery area for a short period to observe your recovery before you are discharged home. You will have received a supply of medications to minimise sickness and to protect the wall of your stomach while the balloon is in place.
As you have been sedated you will not be able to drive yourself home. You will need to be accompanied home by a friend or family member.
During the period that the balloon is in place you need to focus on making changes to your diet and exercise habits so that you maximise your weight loss and adopt habits that can help sustain that after the balloon is removed.
Either 6 or 12 months later you will return to the hospital to have the balloon removed. This is done in much the same way as when the balloon was placed. You will again be sedated and using the gastroscope, the balloon will be punctured, emptied of fluid and then removed.

Am I eligible for the gastric Balloon?
There are many factors to consider for eligibility but providers generally offer the gastric balloon procedure to those with a minimum body mass index (BMI) of 27.
“The dietitian was excellent and speedy with responses, as well as the patient care coordinators. Couldn’t fault the health care staff; they were great.”
“Overall, this entire process has changed me into a better person. It has given me a new perspective on life and more importantly, how I look at myself.”
“I’ve never lost 2 stone on my own, because it is slow for me, but the balloon was a constant reminder to not give up and to keep pushing.”
How much weight will I lose?
Our experience shows that a gastric balloon procedure typically results in a 1.5-2.5 stone weight loss over the first 6 months that the balloon is in place, although some have successfully lost much more. We expect 70-80% of your weight loss to happen in the first 3 months, after which your weight loss slows down or flattens and the balloon plays a more supportive role in helping you to maintain your new weight.
The weight you lose will depend on your starting weight and how well you adapt to the new eating habits the balloon can encourage. There are no miracles in weight loss, as you well know, so it’s important to stay disciplined and focused for good long term results. This is why the nutritional and physical activity aspects of our support plan are so important for long term success.

Common FAQs
Is the gastric balloon effective?
If you work with the rules of the balloon it is a very successful weight loss tool. Most patients lose 1.5 – 2.5 stones in weight although this of course is very individual. It will only work if you take on board the recommended dietary and behavioural changes.
Experience shows that approximately 70-80% of your total weight loss will be lost in the first 3 months. After that, weight loss slows down and the gastric balloon plays a more supportive role in helping you maintain your weight whilst you continue to adapt to new nutrition and exercise habits.
What are the side effects of having a gastric balloon?
The first three to five days can be very difficult. Cramping, nausea and vomiting are normal and should be expected. It is very important that you follow the Gastric Balloon Group instructions and drink plenty of fluids. You will be prescribed medications to ease the discomfort. Serious complications are very rare.
Can the gastric balloon burst or leak?
The balloon has been used in over 300,000 procedures and leaks are extremely rare occurrences. The Allurion and Allurion Plus+ balloons are designed to pass naturally so rupture would not pose any health risk. With the endoscopic BIB and Orbera365 balloons, if the device was to rupture it would require removal. To identify rupture, the fluid inside the BIB and Orbera365 balloons is coloured blue so if a leak were to occur the fluid would empty into your bladder and the urine expelled would be blue in colour. It is highly unlikely that the balloon would deflate in the stomach but if it did you would contact the Gastric Balloon Group team who would arrange for the balloon to be removed.
How long does it take to recover from a gastric balloon?
You should plan at least three days of inactivity to recover from the procedure. You will be able to resume normal activity sooner or later than this depending on how your body adjusts to the intragastric balloon.
