About 40 percent of Americans say their bowel movements, or lack thereof, are disruptive to their daily lives, according to Trisha Pasricha, the Harvard Medical School assistant professor of medicine at Beth Israel Deaconess Medical Center and director of research for the Institute for Gut-Brain Research at BIDMC.
