Weight Loss Balloon: How Gastric Balloons Work
A weight loss balloon is a temporary, non-surgical device placed inside the stomach to help reduce hunger and portion sizes as part of a structured treatment plan. It is intended for people who need support to change eating behaviors and meet weight-loss goals but who may not qualify for, want, or are ready for bariatric surgery. Understanding how it works, who is a suitable candidate, and the possible risks helps people make informed decisions with their healthcare team.

What is a weight loss balloon?
A weight loss balloon (often called an intragastric balloon) is a soft, medical device placed into the stomach to occupy space and create a feeling of fullness. The device may be introduced endoscopically under light sedation or, in some versions, swallowed as a capsule that expands once inside. Balloons are usually made of silicone and are filled with saline or gas. They are intended to be temporary and are used alongside dietary guidance, behavioral counseling, and exercise programs rather than as a standalone solution.
How does a gastric balloon work?
A gastric balloon reduces the effective capacity of the stomach, so patients feel full sooner and eat smaller portions. The balloon can alter hunger signals and support portion control by delaying gastric emptying and promoting earlier satiety. Because it’s a reversible intervention, its use is typically combined with a supervised program that targets long-term habits—nutrition education, physical activity planning, and psychological support—to help maintain weight loss once the balloon is removed.
Is this a medical procedure and what to expect?
Yes, placing a gastric balloon is a medical procedure performed by trained clinicians, usually in an outpatient setting. Preparation often includes medical assessment, blood tests, and discussion of medications. Placement can take 15–30 minutes depending on the method; some balloons require endoscopy under sedation, while others are non-endoscopic. Common short-term effects include nausea, vomiting, and abdominal discomfort as the body adapts. Follow-up visits are needed to monitor tolerance, nutritional intake, and any complications. Removal is also a clinical procedure.
Who might be a candidate for obesity treatment with a balloon?
Candidates typically include adults with overweight or obesity who have tried conservative measures and need additional support but do not qualify for, or do not want, bariatric surgery. Medical evaluation considers body mass index (BMI), obesity-related conditions (such as diabetes or high blood pressure), prior abdominal surgery, and overall medical suitability. Contraindications can include active stomach ulcers, certain gastrointestinal disorders, pregnancy, or prior gastric surgery. A careful consultation with a physician is essential to assess risks and expected benefits for each person.
What happens to the stomach and what is aftercare?
While the balloon is in place, the stomach adapts to a smaller functional volume; this is generally reversible when the device is removed. Aftercare focuses on gradual diet progression—from liquids to soft foods and then regular meals—plus ongoing nutrition counseling and physical activity to reinforce lifestyle changes. Patients typically receive vitamin and mineral guidance if intake is limited. Long-term success depends on behavior modification during and after balloon therapy. Serious complications are uncommon but can include balloon deflation, obstruction, or, rarely, perforation, which require immediate medical attention.
Conclusion
A weight loss balloon provides a temporary, non-surgical option to assist with portion control and satiety as part of a multidisciplinary approach to weight management. It is designed to complement dietary, behavioral, and physical activity changes rather than replace them. Because suitability, methods, and outcomes vary, thorough evaluation by a qualified healthcare professional is important to weigh benefits, risks, and alternatives before proceeding.
