I thought I was the only one. I am a 24 year old female and i too have very hard bowel movements. It's was so bad that it was clogging the toilet. The plumber had to come by three times within 3 weeks to fix the toilet. I was to ashamed to tell my mom that I'm the reason the toilet is messed up. Well anyway my doctor told me to take calcium for my joints since I have lupus, and as I started taking them I realized my bowel movements were not hard anymore. I didn't realize it was the calcium tablets until I ran out and I stopped taking them for a week. Everyone's bodies are different so what might work for some might not work for others but this helped me and maybe it might help someone else
