The treatment of IBS is directed to both the gut and the psyche.

The diet requires review, with those foods that aggravate symptoms being avoided.

Current medical thinking about diet has changed a great deal in recent years. There is good evidence to suggest that, where tolerated, a high roughage and bran diet is helpful. This diet can result in larger, softer stools which seem to reduce the pressures generated in the colon.

Large amounts of beneficial fiber can be obtained by taking over-the-counter bulking agents such as psyllium mucilloid (Metamucil, Konsyl) or methylcellulose (Citrucel).

As many people have already discovered, the simple act of eating may, at times, activate the colon. This action is a normal reflex, although in IBS patients it tends to be exaggerated. It is sometimes helpful to eat smaller, more frequent meals to block this reflex.

There are certain medications that help the colon by relaxing the muscles in the wall of the colon, thereby reducing the bowel pressure. These drugs are called antispasmodics. Since stress and anxiety may play a role in these symptoms, it can at times be helpful to use a mild sedative, often in combination with an antispasmodic.

Physical exercise, too, is helpful. During exercise, the bowel typically quiets down. If exercise is used regularly and if physical fitness or conditioning develops, the bowel may tend to relax even during non-exercise periods. The invigorating effects of conditioning, of course, extend far beyond the intestine and can be recommended for general health maintenance.

As important as anything else in controlling IBS is learning stress reduction, or at least how to control the body’s response to stress. It certainly is well-known that the brain can exert controlling effects over many organs in the body, including the intestine.

In fact, in a recently published study conducted in February 2008 by the national Institute for Health and Clinical Excellence (NICE), hypnosis was named as an approved secondary treatment to conventional medicine for IBS.
