A hiccup is an unintentional movement (spasm) of the diaphragm, the muscle at the base of the lungs. The spasm is followed by quick closing of the vocal cords, which produces a distinctive sound.

Singultus

Hiccups often start for no apparent reason and usually disappear after a few minutes. Rarely, hiccups can last for days, weeks, or months. Hiccups are common and normal in newborns and infants.

• Abdominal surgery
• Disease or disorder that irritates the nerves that control the diaphragm (such as pleurisy or pneumonia)
• Hot and spicy foods or liquids
• Harmful fumes
• Stroke or tumor affecting the brain

There may be no obvious cause for hiccups.
