What really causes a hiccup?

Question

plz

Answer 1

Hiccups are caused when your diaphragm (horizontal, dome-shaped muscle below your chest that helps you breathe) becomes irritated.

Usually, the diaphragm expands and contracts normally, pulling air into and pushing air out of your lungs.  But when this muscle is irritated (usually by eating too fast, overeating, air in your stomach or throat, etc.), it has a minor "spasm"... causing a hiccup to occur, almost like a quick, tiny breath of air.

Answer 2

The part to blame is your diaphragm This is a dome-shaped muscle at the bottom of your chest, and all hiccups start here.

The diaphragm almost always works perfectly. When you inhale, it pulls down to help pull air into the lungs. When you exhale, it pushes up to help push air out of the lungs. But sometimes the diaphragm becomes irritated. When this happens, it pulls down in a jerky way, which makes you suck air into your throat suddenly. When the air rushing in hits your voice box, you're left with a big hiccup.
