There is no known organic cause of IBS. However doctors have highlighted four trigger factors which may worsen symptoms:

Diet

• Eating causes contractions or spasms of the colon. This may result in an urge to have a bowel movement, normally within 30 to 60 minutes after a meal. In people with IBS, the urge may come sooner, with cramps and diarrhoea.

• Contractions may be stronger after a large meal or a meal containing a large amount of saturated fat.

• Other common food culprits include wheat, rye, barley, chocolate, milk products, alcohol and drinks with caffeine, such as coffee, tea, or colas. Also gas-producing foods including beans and certain vegetables like broccoli or cabbage.

Stress, conflict, or emotional upsets

• Stress and strong emotions can affect the bowel as it is controlled in part by the autonomic nervous system.

• The bowel responds to emotions and stressful situations; the colon may contract too much or too little or absorb too much or too little water resulting in constipation or diarrhoea.

Female hormones

• Researchers have found that women with IBS may have more symptoms during their menstrual periods, suggesting that reproductive hormones can exacerbate IBS problems.

Certain medication

• Medication such as iron tablets, painkillers, antibiotics and antacids can also affect the function of the bowel and produce symptoms such as constipation and diarrhoea.
