This is the best description of what IBS is and its possible causes that I have seen.
One of the interesting things it explains is that when you consider the whole IBS population - including those that don't seek medical attention - the amount of psychiatric disorders (anxiety, depression, etc) is not any higher than in the normal population. It is clearly explained that IBS is not a psychological disorder. Also, the presenter puts an interesting prespective on short chain carbohydrates such as fructose, lactose & sorbitol and the role of fiber in managing IBS into clearer prespective.
Thank you for posting the link to this video.
