Old treatments best for IBS
Older "overlooked" treatments for irritable bowel syndrome may end up being the best option for patients, research suggests.
Fibre, anti-spasmodic drugs and peppermint oil were all found to be effective in a review of the evidence.
Guidelines on IBS should be updated in light of the findings, the researchers say in the British Medical Journal.
A UK expert said there had been a general feeling among doctors that the therapies "didn't work".
Between 5% and 20% of the population is estimated to suffer from IBS which is characterised by abdominal pain and an irregular bowel habit.
