We kinda know what happens if you get sucked into a black hole because of math (spaghettification, what outside observers would see, etc); can the same be said about worm holes? Would you even notice if you passed through one? What would they look like? What would someone watching someone else go through a wormhole look like?
Nothing.
You would not feel a thing.
The only known wormholes are so tiny that only single elementary particles can pass through.
Now imagine that not one of the molecules of your body is missing, not one atom from that molecule, but only one elementary particle from one atom.
No way to feel that.

Kinda depends on what that atom becomes once its constituent parts have changed. Perhaps nothing, perhaps it becomes something that explosively cannot exist.
I’m pretty sure a single atom could completely convert to energy, as in perfect E=mc^2 with no losses, and you still wouldn’t notice.
You’d notice if it happened on/near your retina, it was very dark, and you were paying attention. Other than that I don’t think you’re going to notice.
Theoretically could that cause an issue? I’m a computer guy and I think that if one bit on a computer is flipped, that could cause a major issue with the computer, but is that the same with a human?
The bits in a computer have different meaning. Some are super important, others are not. For example that 1 bit on your account balance that decides between 1 million and 2 million :-)
Biological bodies don’t have that flaw. Small parts can also have more significance than others, but the difference is not that problematic. And even such small parts are made of many many atoms.
