Something an incredibly large number of people do not understand is that solid objects cannot pass through you: anything larger than 1-2mm will not get past the Pylorus Sphincter at the end of your stomach.

Any claims otherwise are misled bullshit.

EDIT: Lots of typos

I never threw the quarter i swallowed at 6 years old back up, doc said it likely passed. Thats hella bigger tam 1-2mm and there's no quarters showing up on imaging... so how exactly does that work?

Not saying I don't believe this its just that reconciling this statement with real world experience isn't adding up.

And now I'm picturing the 'Little Book of Calm' getting absorbed and Bill Bailey running around looking like Jesus and quoting it. I never walked around like moose jesus so I guess I didn't absorb it.

Coins will dissolve within a month, pass once small enough. US Quarters are Copper with a plating of Copper Nickel Alloy, all of which will dissolve in acid.

Now that's interesting.

Looks like you typoed the unit of measure. Thats 2 cm, not mm, 10x bigger.

However, exceptions include sharp or toxic bodies, objects too large to pass through the pyloric sphincter (greater than 2×6 cm),

Conflicting Sources

The pylorus contracts to slow gastric emptying and results in further mixing of gastric contents. During this time, the stomach transforms its contents into multiphase slurry called chyme, which is a combination of separate phases of aqueous solutions, fats, and solids. The more intense peristaltic waves promote antral empty- ing, which allows gastric contents, mainly fluid mixed with small particles, to pass through the pylorus and enter the duodenum. The particle size of the food emptied through the pylorus is less than 1 to 2 mm during the fed state (Thomas 2006).

and the Thomas Citation:

Thomas A. 2006. Gut motility, sphincters and reflex control. Anaesthesia Intens Care Med 7(2):57–8.

I think yours is the typo.

I don't read any conflicts here, in fact it seems the blurb you shared is speaking to normal food particle size that passes though, while the one I shared talks about maximum foreign object size that can pass.

When I was a kid, I passed a marble. It was quite painful when exiting the stomach, but I'll never forget the sound of it hitting the porcelain afterwards.

Explain corn in poop

[–] finitebanjo 1 points 20 hours ago* (last edited 20 hours ago)

An unchewed kernel is about 7.5mm in diameter.

The kernels are already popped or deflated as they enter the intestines, the loose corn kernal skins pass through like so.

Huh. TIL
