I am a week and a half out from surgery. I had my first bowl movement Monday and it was painful, I had some formed stools and some soft. Today I was extremely constipated, I sat in the bathroom for a half hour trying to go. Is this normal and am I going to mess up what the dr has done by straining so much? I am on a soft diet, there are certain foods I have to avoid cause they upset my stomach. I'm not sure if I should go back to the liquid diet due to having issues w/ going to the bathroom or will it get better?
