I've been on iron pills for just over 3 weeks and I have to go to the bathroom a lot more often. I was going once per day, which was nice, but now I have to go usually 3x per day since starting the iron pills. I am already eating lots of fiber and havent changed my food habits since before the iron.
I thought oh boy, I should maybe let the doctor know, after all, I should be constipated from the iron! Then I read the box and it says may cause constipation or diarrhea. I'm guessing I have won option #2, and thought that was pretty funny.
Anyone else have to go more often while on iron?
