http://www.womenfitness.net/ibs_quiz.htm I'm embarassed to say I only got 9/10 ! I learned something tho so it's not all bad ...Swedish researchers reveal an intriguing link between appendicitis and IBS. They followed up 212, 218 patients, half of whom had had appendectomies between 1964 and 1993. A total of 613 patients were diagnosed with 1BS/Crohn's disease, and of these 56 per cent had a history of appendectomy. The data shows that appendectomy increases the risk of IBS by three times. Women, those with a perforated appendix, and those who had their appendix out after their tenth birthday had the higher risk of Crohn's disease.
