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.
Hiccups often start for no apparent reason and usually disappear after a few minutes. In rare cases, hiccups can last for days, weeks, or months. Hiccups are common and normal in newborns and infants.
There may be no obvious cause for hiccups.
There is no sure way to stop hiccups, but there are a number of common suggestions that can be tried:
Contact your health care provider if hiccups go on for more than a few days.
If hiccups continue to the point that you visit your health care provider, a medical history will be taken and a physical examination will be performed.
Medical history questions may include:
Diagnostic tests are rarely needed unless a disease or disorder is suspected as the cause.
To treat persistent hiccups, the health care provider may perform gastric lavage or massage of the carotid sinus in the neck. Do not try carotid massage by yourself. This must be done by a health care provider.
If hiccups continue, medicines may help. Tube insertion (nasogastric intubation) may also help.
In very rare cases, if medicines or other methods do not work, treatment such as phrenic nerve block may be tried. The phrenic nerve controls the diaphragm.
