Obesity surgery rates soar on NHS

27 August 2010 Last updated at 06:46 BST

The number of NHS patients having surgery in order to lose weight has increased by nearly 800 per cent in just five years.

The figures show a rapid rise in the number of operations carried out for the most obese people in England.

The release of the statistics coincides with a study in the British Medical Journal which says the upsurge is in part due to patients becoming more aware of the option of surgery.
