Swallowable gastric balloon (Allurion) at Spire St Anthony's Hospital

Being overweight has a significant impact on your health - both physically and mentally. It can lead to low self-esteem, limit your involvement in sports or other activities that could help you regain fitness, prevent you from joining in family fun and lead to time off work through illness or extreme tiredness.

The Allurion gastric balloon is a soft balloon placed in your stomach. It is the first gastric balloon that requires no surgery, endoscopy, or anaesthesia for placement.

The gastric balloon aims to provide a short-term solution if you are struggling to lose weight even after making a real commitment to lifestyle changes, such as a calorie-controlled diet. It can help you lose weight relatively quickly by making your stomach feel fuller for longer after eating relatively small meals.

It can help boost your self-confidence and achieve some health benefits while losing enough weight to become a candidate for longer term weight loss procedures such as a gastric band.

Our consultants are of the highest calibre and benefit from working in our modern, well-equipped hospitals. They have high standards to meet, often holding specialist NHS posts and delivering expertise in complex sub-specialty surgeries. And many consultants have international reputations for their research in their specialised field.

You have a formal consultation with a consultant or other healthcare professional. During this time, you can explain your medical history, symptoms and raise any concerns that you might have. We also discuss with you if any further diagnostic tests, like scans or blood tests, are needed, and let you know if there are additional costs before we do them.

Our dedicated team provide tailored advice to follow in the run up to your visit. And we aim to make your experience with us as easy and relaxed as possible.

Unlike other advanced weight-loss options, the Allurion gastric balloon requires no surgery, no endoscopy and no anaesthesia.

Getting the Allurion gastric balloon takes about 15 minutes. The balloon comes in a capsule with a thin tube. You will swallow the capsule and your doctor will use an X-ray to make sure the balloon is in your stomach. The balloon will be filled through the tube and the tube will be removed, completing the process.

The Allurion gastric balloon removes itself – no need to visit your doctor. After about 16 weeks, the balloon will empty on its own and pass naturally.
