I m 27 about 5 10, and weigh 230 pounds, in the past couple of years, my bowels have been acting up especially when I m under a lot of stress. Even after I ve had a bowel movement, the urge to go again will come back soon afterwards, even just 5 minutes afterwards. Sometimes nothing comes out, it s just an urge. I did once see blood on the toilet paper just streaks of it, but, it was only once, so I m not sure what it means. Is there anything serious wrong or am i just overreacting?
