Weight Loss Balloon: How the Stomach Balloon Medical Procedure Works
A weight loss balloon is a non-surgical option used to help people lose weight by reducing the available space inside the stomach so they feel fuller sooner and eat less. The approach is intended as part of a broader plan that includes diet, exercise, and behavioral support. This article explains how the device works, who may be considered, what the medical steps look like, common risks, and what to expect during and after the procedure.

What is a weight loss balloon?
A weight loss balloon, also called an intragastric balloon, is a temporary device placed inside the stomach to occupy volume and help reduce hunger and portion sizes. Balloons come in different designs: some are filled with saline or air after placement, others are pre-filled and swallowed as a capsule that expands. They are intended to be a short- to medium-term adjunct to lifestyle changes rather than a permanent implant. Selection of a specific balloon type depends on clinical evaluation, patient preference, and the treating center’s offerings.
How does a balloon work in the stomach?
The balloon physically reduces the stomach’s capacity and can slow gastric emptying, which helps create an earlier feeling of fullness during meals. This mechanical effect is combined with structured dietary guidance and behavioral counseling to help patients adopt sustainable eating habits. The balloon itself does not change metabolism long-term; its main benefit is to support portion control and habit formation while a patient follows a supervised weight-management program.
What medical assessments are needed?
Before any intragastric balloon placement, a medical assessment evaluates overall health, previous abdominal surgeries, gastrointestinal conditions, medication use, and mental health. Typical steps include a physical exam, blood tests, and often an upper endoscopy to inspect the stomach lining for ulcers or other contraindications. A healthcare team will also assess readiness for the lifestyle changes required to make the device effective. Patients with certain conditions—such as large hiatal hernia, active gastrointestinal bleeding, or severe psychiatric illness—may not be suitable candidates.
What does the placement procedure involve?
Placement is generally performed as an outpatient medical procedure. Many balloons are inserted endoscopically under sedation, and a healthcare professional fills the device with saline or air once it is in the stomach. Some newer models are swallowed as a capsule and later filled or self-inflate; these may avoid endoscopy at placement but still usually require endoscopic removal. Balloons are temporary and commonly removed after several months, though the exact duration depends on the device and clinical plan. Removal also typically uses endoscopy under sedation.
What are risks, follow-up care, and expected results?
Common short-term side effects include nausea, vomiting, abdominal discomfort, and reflux as the body adjusts. Serious complications are less common but can include balloon deflation, intestinal obstruction, or stomach perforation; prompt medical attention is necessary for severe symptoms. Follow-up includes regular visits with the clinic or multidisciplinary team to monitor progress, adjust nutrition plans, and manage symptoms. Outcomes vary by individual; sustained weight changes depend heavily on adherence to lifestyle changes and ongoing support after balloon removal.
Finding providers and local services in your area
If you are considering a weight loss balloon, consult medical centers that specialize in bariatric or endoscopic weight-loss services. Many hospitals and private clinics offer consultations with a multidisciplinary team including gastroenterologists, bariatric physicians, dietitians, and behavioral therapists. When evaluating local services, review provider experience with intragastric devices, pre- and post-procedure support offerings, and safety protocols. It is appropriate to request information on which balloon models a center uses and typical follow-up schedules to compare programs.
Conclusion
A weight loss balloon is a medical procedure designed to assist with weight reduction by limiting stomach volume temporarily. It can support portion control and behavioral change when combined with structured nutrition and activity plans, but it is not a stand-alone cure. Candidates should undergo careful medical evaluation and commit to follow-up and lifestyle modifications. Discuss options, risks, and realistic expectations with a qualified healthcare team to determine whether this approach fits an individual’s treatment plan.
