A new weight-loss balloon that can be swallowed in a pill has been launched across the UK.
Unlike other gastric balloon treatments, Obalon does not require invasive surgery. Instead, in a 10-minute procedure, patients swallow a capsule the size of a large vitamin pill that contains a deflated balloon.
