Researchers at the University of East Anglia in Norwich have found gastric surgery can halve the risk of heart attacks in obese people.

Doctors reviewed data from 14 studies of more than 29,000 patients who had undergone an operation to reduce the size of their stomachs to help them lose weight.

The surgery was also found to reduce death rates by 40 per cent.
