Quick Facts About Hiccup

hiccup

  • Hiccup is also known as singultus and diaphragmatic spasm.
  • Hiccups occur when a stimulus triggers the nerves which lowers the diaphragm (the muscle that separates the lungs from the abdomen), i.e. makes the diaphragm contract involuntary causing the person to take in a quick breath of air into the lungs. The nerves involved here are linked to the diaphragm.

    The air then causes a brief closure of the glottis (located in the voice box, an opening between the vocal cords). The closure produces the “hic” sound for which hiccups are named.

  • Most hiccups are harmless and they usually stop after a few minutes. Chronic hiccups are very rare. Those that last for months or years are usually called intractable hiccups.
  • The longest hiccup ever known was experienced by an American pig farmer whose hiccups persisted from 1922 to 1987.
  • Did you know that a fetus can have hiccups? They actually help strengthen the diaphragm and prepare the fetus for breathing.
  • Most of the methods used to stop hiccups actually seek to alter the flow of air through the vocal cords so as to stop hiccuping.
