Irregular digestive system
So it's been a while since I've been regular. I usually go to the restroom about once every other day, sometimes less. I've tried laxatives, which only make me cramp up EXTREMELY bad the following morning, stool softeners, which I NEVER see the results of because i can't go, and nothing works. I recently started eating FiberOne bars because my mom said that I needed to increase my fiber intake. Yeah it worked for the first couple of days. More so than I thought it would. But afterwards it went back to more input than output. It causes me to wake up feeling nauseated and have cramps on the left side of my belly and an aching lower back. Sometimes I won't eat breakfast or lunch because I know that everything is all backed up down there and there's nowhere else to put anymore food. I've been to my pharmacist and nothing he recommends ever works either. It all makes me cramp up really bad.
What should I do?
