For some people a gastric balloon is a temporary weight-management option. Suitability depends on the device, the individual and the follow-up plan.

Are gastric balloons obsolete?
No; not all gastric balloons can be described as obsolete. Some devices remain approved for specific uses. Approval does not mean suitability for everyone or equivalence between products. Clarify the device's name and model, approval in the treatment country and the centre's experience.
How does a balloon work?
A balloon occupies part of the stomach to help fullness and is used with nutrition and behavioural changes. No stomach tissue is removed. Placement, removal, filling material and permitted duration differ between products; do not apply one model's instructions to every model.
Limits of the result
This is temporary treatment. Weight loss depends on the product, the individual and participation in the care plan. Maintaining weight after removal or the end of its effect needs a long-term plan. Medication or surgery may suit some patients better. Compare benefits, risks, costs and treatment goals.
Complications to know about
Nausea, vomiting, abdominal pain and reflux may occur and sometimes cause dehydration or require early removal. Serious complications including obstruction, perforation, balloon overinflation or pancreatitis have also been reported. Severe or persistent abdominal pain, repeated vomiting or inability to drink requires urgent assessment.
What should you ask before deciding?
Ask why a balloon is being recommended, about contraindications, the diet plan, exact removal or follow-up dates and emergency access. Ask for total costs including follow-up and possible early removal. Keep scheduled appointments even when feeling well and losing weight.
