What do you call repeated involuntary spasms of the diaphragm?

Best for me has always been after taking a long glass of water! Hiccups usually goe away within a few seconds👍🏽👍🏽

Stomach spasms cause hiccups.

Seeing the reference to low carbon dioxide explains why they say breathe into a brown paper bag.

Every time I see a drunk on tv they always have the hiccups.
