A medically supervised, non-surgical weight-loss program in Montreal

The Allurion Balloon is swallowed as a capsule attached to a thin catheter. Once in your stomach, it’s filled with saline through the catheter, which is then removed. The entire process takes about 15 minutes and doesn’t require endoscopy, anesthesia, or sedation.

Most patients experience minimal discomfort during the swallowing process. Some describe it as similar to swallowing a large vitamin. After placement, you may experience some nausea, cramping, or discomfort for the first few days as your body adjusts to the balloon. Our team provides medication to help manage these symptoms.

After approximately 16 weeks, the balloon’s release mechanism activates, allowing it to deflate. The deflated balloon then passes naturally through your digestive system, similar to a bowel movement. Most patients don’t notice when this happens. No procedure is required for removal.

Most patients can return to work within 1–2 days after balloon placement, although we recommend taking 2–3 days off to allow your body to adjust. While the procedure involves no surgery, anesthesia, or incisions, some patients experience mild nausea or discomfort during the first few days. Many choose to schedule the procedure on a Thursday or Friday so they can use the weekend to recover comfortably.

On average, Allurion patients lose 10-15% of their total body weight during the 16-week balloon period within our 12-month guided program. Full medical support continues throughout the program, with potential for additional weight loss after the balloon. Results vary based on individual factors including starting weight, adherence to the nutrition plan, and lifestyle modifications. Our medical team works with you to set realistic, personalized goals.

The Allurion Program is designed for long-term success. While the balloon helps jumpstart your weight loss, the structured follow-up, nutrition coaching, and lifestyle changes you develop during the program are key to maintaining results. Allurion studies show that up to 95% of the weight lost during the 16-week balloon period is maintained one year later.

Many patients notice changes within the first two weeks. The most rapid weight loss typically occurs in the first 8 weeks, with continued progress throughout the program. Your connected scale and app help you track your progress in real-time.

The Allurion Balloon is typically suitable for adults with a BMI of 27 or higher who haven’t achieved lasting results with diet and exercise alone. During your consultation, our medical team will review your health history, current medications, and weight loss goals to determine if you’re a good candidate.

Patients who have had bariatric surgery (sleeve or gastric bypass) are not eligible for the Allurion balloon program.

Common side effects in the first few days include nausea, abdominal cramping, and acid reflux. These typically subside within 3-5 days as your body adjusts. Our team provides medication to help manage symptoms. Serious complications, like balloon deflation, intestinal obstruction, or ulcers, are rare.

Yes, the Allurion Balloon has received Health Canada approval. It has also been approved by regulatory bodies in over 60 countries and has been used by more than 200,000 patients worldwide.

Both approaches can be effective for weight loss. GLP-1 medications require ongoing prescriptions and may have side effects like nausea or muscle loss. The Allurion Balloon is a one-time, temporary intervention that doesn’t require daily medication. Some patients use both approaches together. Our team can discuss which option—or combination—might be right for you.

The Allurion Balloon is non-surgical, reversible, and doesn’t alter your anatomy. There’s no anesthesia, no incisions, and minimal recovery time. It’s ideal for patients who want significant weight loss without the permanence and risks of surgical procedures. For some patients with higher BMI, bariatric surgery may still be the most appropriate option.

Unlike diet pills, the Allurion Balloon creates physical fullness in your stomach, helping you feel satisfied with smaller portions. It’s a medical device, not a medication, so there are no stimulants or appetite suppressants entering your bloodstream. The structured program also provides accountability and support that pills alone don’t offer.
