It's harder to poop in space. Scientists may finally know why
Astronauts have long struggled with constipation in space. Now, scientists may finally understand why.A new study of 52 astronauts who lived aboard the International Space Station (ISS) suggests that microgravity may slow the movement of food through the intestines, changing how gut bacteria break down nutrients. The findings could ultimately help researchers develop dietary strategies to keep astronauts' digestive systems running smoothly durin…
The hope is that the new knowledge can also be used here on Earth.
Researchers from the University of Copenhagen, in collaboration with NASA, have examined blood from 52 astronauts. They found that intestinal bacteria break down more protein when gravity disappears, which may explain the well-known constipation in space.
