What is a weight loss balloon?

A weight loss balloon is an inflatable medical device placed in the stomach to create a feeling of fullness and to help limit the amount of food consumed. Balloons are typically made of silicone and come in different designs — some are filled with saline or gas and remain in place for a specified period, commonly six months. The goal is to support short- to medium-term weight reduction while patients adopt healthier habits that may be sustained after the device is removed.

How does a stomach balloon work?

A stomach balloon works by taking up space in the stomach, which reduces the volume available for food and can slow gastric emptying. This can lower hunger signals and help patients feel satisfied with smaller portions. The balloon does not alter digestion permanently; rather, it provides a temporary aid to help patients learn portion control and make dietary adjustments. Effectiveness varies by individual and is optimized when combined with structured nutritional and behavioral programs.

Who is a medical candidate for this procedure?

Medical suitability for a weight loss balloon is determined by a healthcare professional based on body mass index (BMI), medical history, and weight-related health conditions. Candidates are often adults who do not qualify for — or prefer to avoid — bariatric surgery, and who have not achieved sustained results through diet and exercise alone. People with prior stomach surgery, large hiatal hernias, certain gastrointestinal conditions, or some medical contraindications may not be eligible. A full medical assessment, including consultation with local services or a specialist in obesity medicine, is essential before considering the procedure.

What does the procedure involve?

The procedure is usually performed endoscopically under sedation or light anesthesia. An empty capsule containing the deflated balloon is guided into the stomach via an endoscope. Once positioned, the balloon is filled with saline or gas to a target volume and the endoscope is removed. The process typically takes less than an hour and is often done on an outpatient basis. Follow-up appointments are scheduled to monitor progress, manage side effects, and provide nutritional and behavioral counseling. Balloon removal is performed endoscopically when the recommended treatment period ends.

Recovery, results, and potential risks

Early recovery usually involves a short adjustment period with nausea, vomiting, or abdominal discomfort as the body adapts to the foreign object; medications and a staged diet protocol are commonly used to manage these symptoms. Weight loss results vary; many patients experience moderate weight reduction during the balloon period, but long-term success depends heavily on post-removal lifestyle changes and structured support. Potential risks include intolerance, gastric irritation, balloon deflation, or rarely more serious complications such as obstruction or ulceration. Regular medical follow-up is important to detect and address complications promptly.

Conclusion

A weight loss balloon is a temporary, reversible medical tool intended to support behavioral and dietary changes for weight reduction by reducing stomach volume and appetite. It is not a standalone cure and requires careful patient selection, close medical supervision, and a commitment to lifestyle modification for sustained benefit. Discussing options with qualified healthcare professionals and local services can help determine whether this procedure aligns with an individual’s health needs and goals.
