Old treatments effective for irritable bowel syndrome

A new study finds fiber, anti-spasmodic drugs and peppermint oil were all found to be effective in a review of the evidence.

As a result, researchers in the British Medical Journal say guidelines on IBS should be updated in light of the findings.

Experts say there had been a general feeling among doctors that the therapies didn't work.

IBS treatments include dietary advice, antidepressants and alternative therapies.
