A gastroenterologist argues that gravity could be a leading cause of IBS, alongside changes in gut microbiome and elevated serotonin levels.

Bad things happen to a human body in zero gravity. Just look at what happens to astronauts who spend time in orbit: Bones disintegrate. Muscles weaken. So does immunity. “When you go up into ...

It could even cause an overgrowth of bacteria in the gut — another cause of IBS. Between 25 and 45 million Americans are blighted by the condition, which is more common in women than men.

A new study has revealed that gravity’s effect on Earth is constantly shaping the surface of our planet. When our planet formed, it did so by pulling dust and rock toward its gravitational field.

Without the pull of gravity to work against, muscle mass decreases and muscles begin to atrophy. Within several weeks, astronauts lose up to 10% to 20% of their lean muscle mass.

The slower growth of gravitational wells and the accelerating expansion might share the same underlying cause.” In so many ...
