What is a gastric balloon?
An intragastric balloon is a soft silicone balloon placed in the stomach via endoscopy (no surgery, no incisions). Once inflated with saline, it occupies space in the stomach, reducing the amount you can eat, increasing early satiety, and supporting weight loss.
Who is a suitable candidate?
The gastric balloon is suitable for patients with BMI 27–40 who want a non-surgical approach, or for those who need to lose weight before bariatric surgery. It is not suitable for patients with previous stomach surgery, active ulcers, or certain other GI conditions.
Procedure and duration
Placement takes approximately 20–30 minutes under mild sedation. Most balloons remain in place for 6 months; some swallowable capsule systems last up to 4 months. After removal, the weight-loss programme continues with dietary and lifestyle support.
Expected results
Average excess weight loss is 25–50%, varying considerably by adherence to dietary guidance. The balloon is a tool to support behaviour change — results are best when combined with nutritional coaching and physical activity.
Frequently Asked Questions
The procedure itself is performed under sedation and is not painful. Some patients experience nausea and discomfort in the first 3–7 days as the stomach adjusts to the balloon.
Yes. Many patients use the balloon as a stepping stone to reach a lower BMI before bariatric surgery, which can reduce surgical risk.
Long-term results depend on maintaining the habits developed during the balloon period. Without sustained dietary and lifestyle changes, some weight regain is common.
