What causes IBS?
The cause is not clear. It is thought that it may be linked to overactivity of part of the gut. The area of overactivity in the gut may determine whether constipation or diarrhoea develops. Again, the cause of overactivity in parts of the gut is not clear. One or more of the following may play a part:
Overactivity of the nerves or muscles of the gut. It is not known why this may occur. It may be linked to overactivity of messages sent from the brain to the gut. Stress or emotional upset may play a role. About half of people with IBS can relate the start of symptoms to a stressful event in their life. Symptoms tend to become worse during times of stress or anxiety.
Infection and bacteria in the gut. IBS is not caused by an ongoing gut infection. However, in about 1 in 6 cases, the onset of symptoms seems to follow a bout of gastroenteritis (a gut infection which can cause diarrhoea and vomiting).
Intolerance to certain foods may play a part in some cases. However, this is thought to be only in a small number of cases.
How can IBS be managed?
Recent research has shown that a prebiotic supplement (galactooligosaccharide) is proven to improve the symptoms of IBS. This supplement is not destroyed, digested or absorbed in the stomach or small intestine and therefore reaches the colon intact to selectively target and feed the body’s immunity boosting bifidobacteria while reducing harmful bacteria, all of which helps to reduce the symptoms of IBS.
