Allurion Balloon FDA-Approved Criteria

The Allurion Balloon received FDA PMA (Premarket Approval) in February 2026, making it the first and only swallowable gastric balloon approved in the United States. The FDA approval established the following eligibility criteria based on the AUDACITY clinical study:

• BMI between 30 and 40 (classified as obese to severely obese)
• Age 22 to 65 years old
• At least one prior failed weight management attempt (diet, exercise, medication, or other methods)
• Not currently pregnant or planning to become pregnant during the treatment period
• No prior gastric or bariatric surgery
• No active gastrointestinal conditions that could interfere with balloon placement or safety

Dr. Davtyan evaluates every patient individually during a consultation. Meeting these basic criteria is the starting point, but your overall health picture matters too.

BMI Calculator: Check Your BMI

Your Body Mass Index (BMI) is a screening tool that estimates body fat based on your height and weight. Here’s how to calculate it:

BMI Formula

BMI = (Weight in pounds × 703) ÷ (Height in inches × Height in inches)

Example Calculations

Example 1: A person who weighs 210 pounds and is 5’6” (66 inches) tall: – 210 × 703 = 147,630 – 66 × 66 = 4,356 – 147,630 ÷ 4,356 = 33.9 BMI ✅ Qualifies

Example 2: A person who weighs 180 pounds and is 5’8” (68 inches) tall: – 180 × 703 = 126,540 – 68 × 68 = 4,624 – 126,540 ÷ 4,624 = 27.4 BMI ❌ Below minimum

Example 3: A person who weighs 250 pounds and is 5’4” (64 inches) tall: – 250 × 703 = 175,750 – 64 × 64 = 4,096 – 175,750 ÷ 4,096 = 42.9 BMI ⚠️ Above standard range (see below)

Don’t worry about doing the math yourself. Dr. Davtyan’s team will calculate your BMI accurately during your consultation and determine your eligibility.

What the BMI Ranges Mean

BMI is categorized into standard ranges recognized by the National Institutes of Health:

The Allurion Balloon targets patients in the BMI 30-40 range — specifically Class I and Class II obesity. This is the population that was studied in the AUDACITY clinical trial, which demonstrated an average of 14% total body weight loss and 2.2x more weight loss compared to diet and exercise alone.

For many patients in this BMI range, the Allurion Balloon fills a critical gap. They may not qualify for — or want — bariatric surgery, and diet alone hasn’t worked. The Allurion Balloon provides a clinically proven, non-surgical solution.

Age Requirements

The FDA approval for the Allurion Balloon specifies an age range of 22 to 65 years old. These limits exist for important reasons:

• Minimum age of 22: The AUDACITY clinical study enrolled adult participants 22 and older. Younger patients may still be growing and developing, and the safety and efficacy data does not extend to adolescents or young adults under 22.
• Maximum age of 65: Patients over 65 may have a higher risk of complications and may have different metabolic responses. The clinical data supporting the Allurion Balloon’s safety profile was collected from participants 65 and younger.

If you are close to these age boundaries, Dr. Davtyan can discuss your specific situation during a consultation. Age is one factor among many in determining the best weight loss approach for you.

Who Should NOT Get the Allurion Balloon

Certain medical conditions and circumstances make the Allurion Balloon unsuitable. Contraindications include:

• Prior gastric or bariatric surgery (gastric bypass, gastric sleeve, lap band, or any stomach surgery)
• Active gastrointestinal bleeding or ulcers
• Large hiatal hernia (greater than 3 cm)
• Inflammatory bowel disease such as Crohn’s disease or ulcerative colitis
• Pregnancy or breastfeeding
• Blood clotting disorders or current use of anticoagulant medications
• Known allergy to materials in the balloon
• Esophageal conditions that could prevent safe swallowing of the capsule
• Severe liver disease or cirrhosis

If you have any of these conditions, Dr. Davtyan will discuss alternative weight loss options that are safe and appropriate for your situation. LapBandLA offers a full range of surgical and non-surgical solutions.

What If My BMI Is Over 40?

If your BMI exceeds 40, you fall outside the standard FDA-approved range for the Allurion Balloon. However, this doesn’t necessarily mean you have no options.

Dr. Davtyan evaluates each patient individually and may consider the Allurion Balloon in select cases based on your overall health profile. In some situations, the Allurion Balloon can serve as a first step — helping you lose enough weight to become a safer candidate for bariatric surgery if needed.

For patients with a BMI over 40, Dr. Davtyan may also recommend:

• Gastric sleeve surgery — a highly effective surgical option for higher BMI patients
• Gastric bypass — for patients with BMI 40+ or BMI 35+ with obesity-related health conditions
• A staged approach — using the Allurion Balloon to reduce BMI before proceeding with a surgical procedure

The key is having a personalized plan. Schedule a consultation with Dr. Davtyan to explore all your options.

What If My BMI Is Under 30?

If your BMI is below 30, the Allurion Balloon is not FDA-approved for you. The clinical evidence supporting the balloon’s safety and effectiveness was established in patients with a BMI of 30 or higher.

But that doesn’t mean you’re out of options. For patients with a BMI of 25-29.9 (overweight range), Dr. Davtyan may recommend:

• Medical weight loss programs — physician-supervised plans with appetite suppressants and lifestyle coaching
• Nutritional counseling — personalized meal planning with registered dietitians
• CoolSculpting or body contouring — for stubborn fat pockets rather than overall weight loss
• GLP-1 medications — certain GLP-1 drugs are approved for patients with lower BMIs who have weight-related health conditions

Dr. Davtyan will help you find the right fit. Even if the Allurion Balloon isn’t the answer, there’s always a path forward.

Frequently Asked Questions

What BMI do I need for the Allurion Balloon?

You need a BMI between 30 and 40 to qualify for the FDA-approved Allurion Balloon. This corresponds to Class I and Class II obesity. Dr. Davtyan’s team will calculate your exact BMI during your free consultation and help determine your eligibility.

Can I get the Allurion Balloon if my BMI is 29?

The Allurion Balloon is FDA-approved for BMI 30-40, so a BMI of 29 falls below the approved range. However, BMI can fluctuate. If you are very close to 30, schedule a consultation with Dr. Davtyan to discuss your options. There are other effective non-surgical weight loss solutions that may be appropriate.

What if I’ve had gastric sleeve or lap band surgery before?

Prior gastric or bariatric surgery is a contraindication for the Allurion Balloon. The altered stomach anatomy from previous surgery may not safely accommodate the balloon. Dr. Davtyan can discuss revision surgery or other alternatives during a consultation.

Is there a weight limit for the Allurion Balloon?

The FDA approval specifies a BMI range of 30-40 rather than a specific weight limit. Your BMI depends on both your weight and height. For example, a 5’6” person with a BMI of 40 weighs approximately 248 pounds, while a 6’0” person with a BMI of 40 weighs approximately 295 pounds.

Do I need to have tried other diets before qualifying?

Yes. The FDA criteria require at least one prior failed weight management attempt. This can include dieting, exercise programs, commercial weight loss programs, medication, or any other supervised attempt at weight loss. Most patients who seek out the Allurion Balloon have already tried multiple approaches.

How do I check if I’m eligible without coming in?

While online BMI calculators can give you a rough estimate, the most accurate eligibility assessment happens in person. Dr. Davtyan considers your full health history, not just your BMI. Call 877-9-BE-SLIM to schedule a free consultation — there’s no obligation, and you’ll leave with a clear understanding of your options.

Can I use the Allurion Balloon with a walking guide by BMI to improve my results?

Absolutely. Combining the Allurion Balloon with regular physical activity — including a structured walking program tailored to your BMI — can enhance your weight loss results and help you build habits that last long after the balloon passes.
