HICCUP

A hiccup or hiccough is a myoclonus of the diaphragm that repeats several times per minute. In humans, the abrupt rush of air into the lungs causes the vocal cords to close, creating a "hic" sound.

n medicine it is known as synchronous diaphragmatic flutter (SDF), or singultus, from the Latin singult, "the act of catching one's breath while sobbing".[1] The hiccup is an involuntary action involving a reflex arc.
A bout of hiccups, in general, resolves itself without intervention, although many home remedies shorten the duration. Medical treatment is occasionally necessary in cases of chronic hiccups.
