Familial Tendency

There is epidemiological evidence that IBS has a familial component. Having a relative with IBS slightly increases the risk of other family members suffering from IBS. IBS may also be present across generations (particularly in mothers and daughters), and first degree relatives of IBS patients are twice as likely to have IBS as the relatives of the IBS patient’s spouse. Studies of twins suggest that both genetic and environmental factors are important in contributing to IBS.
