Weight loss balloon in a pill
A gastric balloon in pill form called 'Obalon' has just been launched in the UK.
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.
The balloon is designed to be used by people with a body mass index (BMI) of 27 or above, who have previously failed to lose weight through diet and exercise. Normally surgery is needed to insert a gastric balloon.
Each balloon cost £1995 and lasts 12 weeks. It is currently not available on the NHS.
