Answer 2

Hiccups are sudden, involuntary contractions of the diaphragm muscle. As the muscle contracts repeatedly, the opening between the 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.

Hiccups are rarely a cause for concern, but if hiccups become frequent, chronic, and persistent (lasting more than 3 hours), if they affect sleeping patterns, interfere with eating, cause reflux of food or vomiting, occur with severe abdominal pain, fever, shortness of breath, spitting up blood, or feeling as if the throat is going to close up, see a doctor.
