hiccup (redirected from Chronic hiccup)

hiccup or hiccough, involuntary spasmodic contraction of the diaphragm followed by a sharp intake of air, which is abruptly stopped by a sudden, involuntary closing of the glottis (opening between the vocal cords); the consequent blocking of air produces a repeated characteristic sharp sound, or hic. It is believed that hiccup is caused by stimulation of the nerve pathways or centers that control the muscles of respiration, particularly the diaphragm. In most instances hiccups are transient, although their course may sometimes be shortened by such measures as holding the breath, deep regular breathing, or rebreathing into a paper bag to increase the carbon dioxide content of the body. However, persistent hiccups may last for weeks, months, or even years. When hiccups are prolonged, therapy may include the administering of certain drugs, inhalation of carbon dioxide, and even interruption of the phrenic nerve either by injection of an anesthetic or by surgery.

hiccup

Spasmodic contraction of the diaphragm that causes a sudden breath in, cut off when the vocal cords snap together, creating the characteristic sound. Causes include overdistended stomach, gastric irritation, and nerve spasms. The many folk remedies for hiccups interrupt the rhythm of the spasms. The most common and effective treatment is to hold the breath as long as possible. Hiccups usually stop within minutes, though they may last days, weeks, or longer. Prolonged severe hiccups are treated with nerve blocks or by surgically cutting the nerve that supplies the diaphragm.
