It is possible that the main title of the report Hiccups, Chronic is not the name you expected. Please check the synonyms listing to find the alternate name(s) and disorder subdivision(s) covered by this report.
A hiccup is an involuntary spasmodic contraction of the muscle at the base of the lungs (diaphragm) followed by the rapid closure of the vocal cords. Usually, hiccups last for a few hours or, occasionally, a day or two. However, chronic hiccups are ones that continue for an extended period of time. Episodes that last for more than two days and less than a month are sometimes called persistent hiccups. On rare occasions, hiccups persist even longer than a month or recur frequently over an extended period of time. The longest recorded episode of these chronic hiccups lasted 60 years.
Sometimes, although not always, hiccups that persist may indicate the presence of another medical problem. Some illnesses for which continuing hiccups may be a symptom include: pleurisy of the diaphragm, pneumonia, uremia, alcoholism, disorders of the stomach or esophagus, and bowel diseases. Hiccups may also be associated with pancreatitis, pregnancy, bladder irritation, liver cancer or hepatitis. Surgery, tumors, and lesions may also cause persistent hiccups.
