The Allurion Programme is ideal if you:


The cost for the 6-month multi-disciplinary program is £3.95k. This includes all costs associated such as medication, 16-week Allurion Balloon, Balloon placement, a digital scale, access to the Allurion app and watch, as well as six months of follow-up with our experienced nutritionist to help change your relationship with food for the long term. 0% finance is available through Spire.

If you have difficulty swallowing the balloon, Mr Monkhouse will revert to using a stylet – a fine flexible wire to help guide the capsule down into the stomach. Mr Monkhouse demonstates this technique in a video on his Instagram. 3 in 10 patients require this.  If you have anxiety, a light relaxant can be provided to take prior to having balloon placement. 

Weight loss results vary from person to person and depend on various factors such as adherence to the program, initial weight, and lifestyle habits. Average weight loss is between 10-15%. Some patients lose significnantly more weight than average.

The Allurion balloon is designed to be a temporary weight loss solution and typically remains in the stomach for approximately four months. After this period the balloon valve degrades and you pass the balloon naturally.

Yes, as part of the Allurion program, you will receive guidance on dietary modifications to optimize your weight loss results from a BDA Registered Dietician. Our Dietician’s will work with you to develop a personalized meal plan tailored to your needs and preferences.

Yes, incorporating regular physical activity into your routine is encouraged while on the Allurion program. Exercise can complement your weight loss efforts, improve overall health, and enhance results. However, it’s essential to consult with your healthcare provider before starting any new exercise regimen, especially if you have any underlying health conditions.

After approximately 16 weeks inside your stomach, a time-activated release valve will open, allowing the balloon to empty and pass naturally through the gastrointestinal tract without the need for a removal procedure.*

*In rare cases, the Allurion Balloon may require endoscopic or surgical intervention for removal.

Up to 96% of weight-loss may be sustained 12 months after the Balloon exits the body!

After the less than 20-minute placement, you can continue with your life; however, you may have some symptoms for a few days such as nausea, vomiting and stomach cramps. Your healthcare professional will advise you on care and nutrition after placement and the best plan to resume your activities, such as gym and exercise.

The placement takes place during a less than 20-minute outpatient visit. Allurion is the first gastric balloon that requires no endoscopy* or anaesthesia for placement or removal. Simply swallow a capsule containing the deflated Balloon with a catheter: once the Balloon is confirmed to be in your stomach via x-ray, the Balloon is filled with water through a catheter. A second x-ray takes place to ensure the Balloon is filled correctly.

Yes! The Allurion Program, a combination of our unique swallowable gastric balloon and a supported lifestyle change program, leads to nearly 2.5 times the weight loss than a lifestyle change program alone, according to an independent study.(superscript 1)

In another study, three-quarters of participants who attempted to lose weight over a year through calorie-controlled or restricted diets (72% of participants), exercise programs or courses (22%), and pharmaceutical treatments (12%), did not achieve a clinically meaningful weight loss defined as at least 5% of their body weight.(superscript 2) The evidence shows that these isolated methods alone are not enough.

The 6-month Allurion Program combines medical support and a weight-loss device (Allurion Gastric Balloon), digital tools (Allurion Connected Scale, Allurion Health Tracker and Allurion App) and nutritional coaching to kick-start your weight loss and help you form lifelong healthy habits to maintain the weight loss.

The Allurion Balloon is the world’s first and only gastric balloon without the need for surgery, endoscopy* or anaesthesia for balloon placement and removal. The balloon is swallowed as a capsule during a 15-minute placement which means less downtime or time off work for our patients.
Designed to pass naturally at approximately 16 weeks, the Allurion Balloon maximizes weight loss while minimizing time spent in the body, making it a more effective option than longer 6-month endoscopic balloons, where 80% of weight loss is achieved within the first 3 months.1

The Allurion Balloon is a safer option, with fewer side effects. It has a significantly lower intolerance rate compared to 12-month endoscopic balloons (1-3% vs 14.4%)2,3, with an overall serious adverse event rate that is 10 times lower than other liquid-filled balloons.4-10

Made from vegan polyurethane, a material that’s much thinner and more flexible than the silicone material in endoscopic balloons, the Allurion Balloon flexes and adapts as your stomach moves, ensuring a snug and comfortable fit.
