Pooping shouldn’t be a drawn-out process. You’re better off keeping your toilet time to less than 10 to 15 minutes, says Gregory Thorkelson, M.D., a psychiatrist in the department of gastroenterology, hepatology, and nutrition at the University of Pittsburgh.

In fact, you should only make your way to the bathroom when the urge hits.

If the urge to poop isn’t there, you might be tempted to push or strain to try to get the job done.

And all that straining could lead to the development of hemorrhoids—bulging blood vessels around your anus that can become swollen and painful or even bleed.
