Exclusive Air Filled Gastric Balloon for Weight Loss
Lose up to 18% bodyweight in 6 months

The Heliosphere Balloon Program

Exclusive to Gastric Balloon Group

The Heliosphere balloon is a non-surgical weight loss solution. Inserted endoscopically through the mouth, this balloon is filled with air, taking up space in the stomach and promoting a feeling of fullness during meals. No hospitalisation is needed, and the balloon stays in place for 6 months until it’s removed endoscopically. 

Fully inflated with air, the Heliosphere balloon weighs just 10g and its lightweight design helps to minimise side effects, giving a more comfortable experience than traditional saline-filled balloons. You can resume normal activities quickly after implantation for a convenient and effective approach to weight management.

The Heliosphere Balloon Placement

The Heliosphere placement is a quick and easy treatment that can be completed as a day case, allowing you to resume your daily activities immediately with little downtime required. Fully inflated with air, the Heliosphere balloon weighs just 10g


You will be admitted as a day case patient at your chosen hospital and taken to an endoscopy suite.


You will be semi-conscious throughout the 20 minute procedure but sedated for your comfort. It is not a general anaesthetic.

The consultant will check the health of your stomach with a camera. Then using an endoscope (long tube), the soft deflated balloon slides through your mouth, down your throat and into your stomach. Once filled with air, the balloon is detached and the tube is removed.

You will be in hospital for 3-4 hours,  there is no overnight stay. As you have been sedated, you won’t be able to drive so you’ll need someone to take you home.

The balloon stays in place for up to 6 months, before it is removed in a similar 20-minute day case procedure. Again you will be sedated whilst the balloon is emptied and removed endoscopically.

Gastric Balloon FAQ's

The balloon is placed in the stomach during a 15-20 minute procedure. You will be conscious but sedated so won’t feel any discomfort. The deflated balloon is inserted into your stomach through your mouth (endoscopically). When the balloon is in the stomach it is filled with air and the tube is removed. You will remain in the clinic for observation until the doctor discharges you.

The time it takes to recover after a gastric balloon differs from person to person and will depend on how quickly your body adjusts to the balloon. Generally you should plan at least three days of rest to recover from the procedure before you resume normal activity.


You will be on clear fluids only for the first few days after your procedure as you go through the period where your body is adjusting to the balloon and you are likely to be vomiting or feeling nauseous. During this period, remember to keep hydrated. Following the dietary regime as advised by the patient support team and the balloon will help you to reduce your portion sizes. There are no particular restrictions as to what you can eat or drink although, for lasting success with the balloon, this is the time to evaluate your eating habits and try and reduce the amount of alcohol, high fat and high sugar foods in your diet.


How much weight you will lose and how quickly varies from person to person and will depend on how well you adapt to the gastric balloon and how much you are prepared to adjust your lifestyle, eating habits and activity levels. Experience has shown, however, that 70-80% of weight loss typically occurs during the first three months of treatment.


The balloon is punctured and emptied and the deflated balloon is removed through the mouth. Again you will be conscious but sedated so won’t feel any discomfort. You will remain in the clinic for observation until the doctor discharges you but this is usually only for a very short time. You should not experience any side-effects other than a possible sore-throat for a day or two.

This can differ from person to person but most people say they can’t feel the balloon as such, rather a feeling of fullness in their stomach.

With the air-filled Heliosphere balloon, you will feel no weight or heavy pressure in your stomach. Weighing just 10g rather than the typical 450g of a saline filled balloon,  Heliosphere offers a more comfortable experience with the potential for fewer side effects.
