I will mildly agree with this post. Definitely get a doctor to take a look. I have been going through workups for the past couple years for a similar situation. I shit a ton. Right now they are working on identifying whether it is IBS or IBD. They are leaning towards Crohn's, but aint nobody got time for that. I have enough autoimmune diseases as it is. Cancer was also brought up, but luckily they haven't found anything along those lines. I also get to go in and have cameras shoved up my butt and down my throat every five years. But hey, at least I'm not fat.  :D
