Most of the UK media has got rather overexcited about the UK launch of Obalon, a gastric balloon in pill form that can be swallowed to help overweight people achieve rapid weight loss without invasive surgery.
The Obalon pills are designed to be inflated into balloons in the stomach, reducing the free volume of the stomach and therefore how much a person can eat before they feel full.
Intra-gastric balloons are not new, and are sometimes provided to extremely obese people through the NHS, although these often have to be surgically implanted.
