There’s a lot of research on this. It’s really not a good idea to hold in your poop, especially repeatedly and for a very long time.  There was a case of a teenager from England who died after not pooping for eight weeks. Pooping is really just the practice of emptying your bowels. It’s essential for good health! If you don’t poop, your body will recirculate fecal water throughout the body. That’s pretty gross when you think about it. If you want to poop but can’t, you should see a doctor. You could also try a stool softener or fiber pills. Then, again, that’s different from wanting to temporarily hold in your poop to avoid simple momentary embarrassment.   Although experts say holding your poop briefly until you can find a socially acceptable time to do it is unlikely to cause you serious problems, they have found that people who do so regularly because of their profession might end up with issues like constipation (say teachers or truck drivers). This is defined as you accidentally passing a stool from your rectum. If you can’t make it to the bathroom on time repeatedly, see a doctor.  Stool is the term used for solid waste that is passed as a bowel movement, more commonly called poop.   Bowel control problems are fairly common, affecting about 18 million adults in the United States. They are more common in older people, but anyone can get them. Difficult childbirth, poor overall health, and disease or injury can be causes. People use a muscle called the puborectalis muscle to poop. This muscle is basically a sling for your rectum.  When you sit down on a toilet, the hold on your rectum is partially loosened. If you were to squat, the hold would be completely relaxed, making it easier to poop. Poop is a combination of fiber, bacteria, other cells, and mucus. Soluble fibers like beans and nuts become part of your poop. Some foods are harder to digest, like corn or oat bran.
