Constipation in space: Blood tests from 52 astronauts indicate a change in gut bacterial activity
Constipation in space: Blood tests from 52 astronauts indicate a change in gut bacterial activity
The astronauts' blood showed an increase in substances that indicate protein fermentation by gut bacteria. Researchers suspect that the slower passage of food through the gut in microgravity may explain the phenomenon—but the transit time
