Ok, I am 29 years old, and have always had problems with my bowels. But, the last year or so, things have gotten really bad. I will go for 1-2 weeks being coonstipated, then have bloody diarrhea for 2-3 days, then go back to being constipated. I had a colonoscopy the 1st of this month, and was supposed to go back in and get my hemerroids banded on the 7th.
