How does the stomach work in space? Do astronauts feel constant need to throw up since the contents are bouncing around inside?

Answer 1

Óir bodies are very good at keeping everything compact. While aided by gravity, one can digest anything in 0-G, and even upside down, since the entire process is muscularly controlled.

But no – astronauts get extensive training to *not* throw up. Most are/were former fighter pilots and have really good control.
