The gastric balloon is a medical device designed to assist with weight loss. It is a soft balloon filled with liquid or air that is placed in the stomach. All gastric balloons have the same mechanism of action to occupy space, promoting a feeling of fullness and reducing food intake4. They typically remain in the stomach for several months before being removed by endoscopy or, in the case of the Allurion Balloon, naturally eliminated.**
We understand that swallowing the capsule containing the Allurion Balloon may worry some people, particularly due to the gag reflex.
A clinical study conducted with 1,770 patients showed that 99.9% of patients were able to swallow the capsule. Only one patient was unable to swallow the device. In 35.9% of cases, patients required assistance from a stylet to facilitate ingestion1. In such instances, the doctor helped by gently guiding the capsule down using the stylet, which helps to stiffen the catheter.
After approximately 4 months 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.4*
Curious about the specifics of the Allurion Balloon removal? Dive into this detailed exploration on what the process involves.
We understand that weight regain after balloon passage is a common fear and source of anxiety. This is why the Allurion Balloon is accompanied by nutritional coaching and medical support to help you change your lifestyle and develop a healthier routine. Once the Allurion Balloon is out of your body, the support from your follow-up team continues until the end of the Allurion Programme to help you maintain the same eating habits.
The Allurion Balloon is placed in the stomach during an outpatient consultation.4 The patient swallows a capsule containing the deflated balloon, which is attached to a thin tube (catheter). Once the presence of the capsule in the patient’s stomach is confirmed (by X-ray), the balloon is filled with liquid using the catheter. A second X-ray is performed to ensure that the balloon is properly filled. The procedure is then complete, and the catheter is gently removed. In the majority of cases, approximately 4 months later, the Allurion Balloon empties on its own and is naturally eliminated.4**
Clinical evaluation of the Allurion Device suggests that on average, patients will lose approximately 10-15% of their starting total body weight4. Individual results vary widely.
If weight loss achieved is less than desired and the patient still qualifies and is not contraindicated, a sequential Allurion Device may be placed.
As with any medical solution, results may vary from patient to patient, and some may not respond to the treatment. Please consult a doctor to assess the risks and benefits before making your decision.
GLP-1s can play a valuable role in weight management, but only as part of a comprehensive approach. The Allurion Program reframes how patients engage with food and their health - combining appetite regulation with fullness training, behaviour change and personalised support.
Our goal is to shift the conversation from how much weight is lost to what kind of weight is lost, and how health is improved. By combining our procedureless gastric balloon, connected digital tools, AI coaching and clinician-led care, we’re setting a new standard for obesity treatment.
Our programme acts as the central pillar to any program, working effectively alongside other treatments like surgery, weight loss pills, and GLP-1 jabs. With GLP-1s, we are pioneering a low dose combination approach that not only enhances weight loss but also preserves and builds lean body mass.
Early data shows patients using Allurion with low-dose GLP-1s achieved up to 20% total weight loss and a 15% increase in muscle mass in just eight months. That’s what metabolically healthy weight loss looks like.
Metabolically healthy weight loss is about more than the number on the scale. It focuses on long-term fat loss, muscle preservation, and improvements to overall metabolic health, including blood sugar regulation, energy levels and reduced risk of chronic disease.
Weight loss, weight maintenance and muscle gain must go hand in hand. That’s why the Allurion Program supports fat reduction while helping patients retain lean muscle mass and build sustainable habits for life.
