I have had a colonoscopy done and nothing was found wrong. Before I would have 2-3 full bowel movements a day . Now I do have bowel movements but I have to strain or sit in a different position on the toilet to try and get it out. And when it does come out, I feel like there is more that needs to come out. And I do not feel the urge to go to the bathroom. There is always pressure below my belly button but no pain. My stomach is distended all the time when I eat. In the morning is when my stomach is the flattest and then after the day goes by it just sticks out. I think it may be a Pelvic Floor Dysfunction or a tightening of the sphincter . The digestive process goes all the way through but then once it gets to the rectum it just gets stuck and its hard to pass it through to the end.
