This is all true but not the “rule” and no part of any of these studies says that digestion is “gravity based” and in fact many astronauts have no problem with their digestion. Some do, some don’t. Space and microgravity can exacerbate issues and cause acid reflux for all the reasons cited, but again, not the rule, and most astronauts adapt. UK astronaut Tim Peake has given talks about how you feel full faster because the lack of gravity’s “tug” but otherwise, as this paper describes, the primary force for pushing food down and through your winding tubes is peristalsis, in some people this action is strong enough for astronauts or burrito-eaters to not feel ANY ill effects eating and then changing orientation, in some people, everything flies right out both ends.
Either way, most bodies adapt to conditions they’re in regularly, and it’s just wrong to characterize digestion as reliant on gravity and an upright position, or eating before bed as leading inevitably to “irritable bowels, and leaky butthole, hemorrhoids and bloody stool.”
You said it wasn’t gravity based, cited space travel, I provided evidence directly contradicting you and you said “yes thats all true, but [paragraph] [paragraph]”

I’m glad you reversed your stance after being presented the facts, thank you for being reasonable.
Oh, so you’re not having a conversation but you’re in fact unhinged. I see now. Have a good one. blocked.
