When we sit upright, the puborectalis muscle (one of many muscles in the pelvic floor group) has tension and “kinks” the rectal canal which can decrease or fully eliminate the ability of the feces to pass. When this occurs we tend to strain or force. Straining or forcing can result in many other issues such as hemorrhoids, rectal prolapse, or even cardiac complications (from Valsalva maneuver). If, on the contrary, we are able to improve our analrectal angle with positioning the puborectalis muscle can relax and stool should pass more freely.
