You can do things to empty your bowels although our bowels are never fully empty as we continue to produce poop and fecal matter which fills our bowels back up normally.
since stool is made up in large part of bacteria, fecal matter is continuously being formed.
In addition to bacteria, stool is made up of liquid, undigested food, dietary fiber, fat, minerals, and protein.
Rectal tenesmus, or tenesmus, is a feeling of being unable to empty the large bowel, even if there is no remaining stool to expel.
Several medical conditions can cause tenesmus.
These include inflammatory bowel disease (IBD), colorectal cancer, and disorders that affect how the muscles move food through the gut.
