Does anyone have a ph d. In biology , or other ,with a specialty in hiccups?

Tranquilizers are used for long term hiccups (like days in a row).
Cause is an irritation of a nerve that goes to the chest from the neck.

Specialists who may be involved in treating hiccups include an otolaryngologist (an ear, nose, and throat specialist, or ENT), a gastroenterologist (a specialist in the digestive tract), a neurologist (a specialist in the brain and nervous system), a pulmonologist (a lung specialist), or a psychologist.

I hear hospitals use a spoonful of sugar to cure hiccups. I drink a full glass of water while turning the glass. A friend of mine drinks a full glass of water from the far side (upper, as you face the glass) of the glass.(Quite a feat, kind of upside-down like.) Both of us say our methods work 100% of the time.

The best cure is to stop breathing for a bit. While on the subect, why do some ppl have cute little hiccups & others full body hiccups?

Hold your breath while drinking 13 sips of water. Works everytime.

OP is regarding the study of, not home remedies.
Yes, lots of study has gone into hic hic hiccups, and various remedies.

Looks like there’s a study going on here right now…
