Be sure to watch the funny videos of animals having hiccups at the end of this post.
Hiccups are repetitive, uncontrollable contractions of the diaphragm muscle. They occur when something irritates the diaphragm into a sudden contraction, quickly pushing air up into the lungs. Each spasm of the diaphragm makes the vocal cords and larynx suddenly close. The body then reacts with a gasp and a noise, creating the sound characteristic that we relate to hiccups.
