ELI5: How does acid stay in a person’s stomach after death and not begin to immediately eat away at the body?

 Not that your physical condition would be a concern at that point, but I wonder how the stomach doesn’t immediately loose the acid into its surroundings with everything shutting down.

Technically it does start eating away at the body when you die. It always does, which is why our stomach lining is constantly replenishing itself.
However, stomach acid and bile aren't so potent that they'd burn a hole right through you, so our thick stomach walls get eaten away slowly in time with normal anaerobic decay and such.
