Does gender play a role in irritable bowel syndrome?

ANSWER

Women are about twice as likely to have IBS as men. A growing body of research shows that sex hormones, like estrogen and progesterone, may be the reason. They can trigger IBS symptoms, which may explain why you have more flare-ups at different points of your menstrual cycle.
