Swallowable balloon can help people with obesity to shed weight

A swallowable balloon can lead to a dramatic weight loss over months but is only a temporary solution for obese patients, a medical expert warns. 

A study found that obese people lost around 2st 6lb (15kg) over 16 weeks when they used the balloon that makes people feel full.

The Elipse Balloon, which costs under €4,000, is available privately in Ireland. It is in a capsule that is swallowed with a drink of water.
