Hiccups are sudden, involuntary contractions of the diaphragm muscle. As the muscle contracts repeatedly, the opening between your vocal cords snaps shut to check the inflow of air and makes the hiccup sound. Irritation of the nerves that extend from the neck to the chest can cause hiccups.


Many conditions are associated with hiccups, but none has been shown to be the cause of hiccups.

Numerous home remedies for hiccups exist. The reason that these remedies are thought to work is that carbon dioxide build-up in the blood will stop hiccups, which is what happens when you hold your breath. If the vagus nerve that runs from the brain to the stomach is stimulated, hiccups can also be alleviated (this is what is happening when you drink water or pull on your tongue).</LI>
