I have a friend who has irritable bowel syndrome. Almost anything he eats can upset his stomach and lead to diarrhea. I guess it goes without saying that this condition can lead to some awkward situations, but what some people don't know is that the condition can also be dangerous.
My friend has to go to the doctor several times a year and have the test that checks for polyps of cancer in his intestines. So far he has had some polyps removed, but none of them have been cancerous, so he is lucky in that regard. However, living with the condition is no piece of cake.
