Gastric balloon is the option we recommend most often to patients who want meaningful weight-loss support without committing to permanent surgery — it's temporary, reversible, and the procedure itself takes about 15 minutes.
What actually happens during the procedure
A deflated silicone balloon is inserted into the stomach via the mouth using an endoscope, under light sedation rather than general anaesthesia in most cases. Once positioned, it's filled with saline solution until it reaches the intended size, taking up space in the stomach so you feel full on smaller portions.
The adjustment period nobody skips
The first 3-5 days are the hardest part — nausea and mild discomfort as your stomach adjusts to the balloon's presence are common and expected, usually managed with anti-nausea medication. Most patients are back to a completely normal routine within about a week.
What it's actually designed for
- A structured 6-12 month window (balloon type dependent) to build sustainable eating habits, not a permanent standalone fix
- Patients who aren't candidates for surgery yet, or want to lose weight before a different procedure to reduce surgical risk
- A typically lower price point than surgical options, useful for patients testing whether they're ready for a bigger commitment
What actually happens when the balloon comes out
Removal is another quick endoscopic procedure once the placement period ends. Long-term success depends heavily on the dietary coaching that comes with the programme — the balloon creates the opportunity to build new habits, but it's the habits, not the balloon itself, that determine whether the weight loss lasts.
