1. The Medical Term for Hiccup is Singultus
The word singultus is Latin for “to catch one’s breath while crying.” The blog Medical Student’s Diaries defines the motion of a hiccup as the involuntary contraction of the diaphragm, occurring at the same time as the contracting of the voice box, and the closure of the glottis, which together blocks air intake. The glottis is located in the middle part of the larynx, where the vocal cords are, and when it snaps shut, it causes that telltale hiccup noise.
2. Hiccups Have Many Different Causes
Hiccups can be caused by shock, stress, alcohol consumption, smoking, a sudden change in temperature, excitement, and overeating. Many of these things irritate the esophagus, which can triggers the hiccups.
3. Hiccups Should Be Short-Lived
If your hiccups last for two days or more, you could be at risk for serious health problems. Hiccups that won’t quit could signal a range of medical conditions including ulcers, malaria, and even cancer.
