About a month ago, at an event for health journalists, I heard a colorectal surgeon say something that nearly made my eyeballs bug out of my face. “All of us have hemorrhoids, all the time,” she said.Uh, no, nope. There’s no way. All these healthy-looking people sitting comfortably on their bums around me have hemorrhoids?!So I called her up after the event and asked her what she meant by that inflammatory (sorry) comment. Never in my life did I think I’d spend 45 minutes on the phone casually throwing around phrases like “anal canal.” I also didn’t know there was so much to learn about hemorrhoids. Here are the dirty details everyone should know.
