Differential Diagnosis for Intractable Hiccups

Intractable hiccups are hiccups that last for more than 48 hours and can be caused by a variety of factors. Here are some differentials for intractable hiccups, categorized for clarity:

  • Single Most Likely Diagnosis

    • Gastroesophageal reflux disease (GERD): This is often considered the most likely diagnosis because GERD is a common condition that can irritate the nerves that control breathing, leading to hiccups. The stomach acid can flow up into the esophagus and stimulate the nerves, causing hiccups.
  • Other Likely Diagnoses

    • Gastritis or esophagitis: Inflammation of the stomach or esophagus can irritate the nerves and cause hiccups.
    • Laryngitis or pharyngitis: Inflammation of the larynx or pharynx can also irritate the nerves and cause hiccups.
    • Pneumonia or other lung infections: Infections in the lungs can cause irritation of the nerves that control breathing, leading to hiccups.
    • Stroke or other central nervous system disorders: Certain conditions that affect the brain or nervous system can cause abnormal breathing patterns, including hiccups.
  • Do Not Miss Diagnoses

    • Myocardial infarction (heart attack): Although less common, hiccups can be a symptom of a heart attack, especially in women. It's essential to consider this diagnosis to avoid missing a life-threatening condition.
    • Pancreatitis: Inflammation of the pancreas can cause abdominal pain and hiccups, and it requires prompt medical attention.
    • Pneumothorax: A collapsed lung can cause hiccups, among other symptoms, and requires immediate medical attention.
  • Rare Diagnoses

    • Neurosyphilis: A rare condition caused by syphilis infection of the nervous system, which can cause hiccups among other symptoms.
    • Multiple sclerosis: A chronic condition that affects the central nervous system and can cause a range of symptoms, including hiccups.
    • Medullary thyroid cancer: A rare type of thyroid cancer that can cause hiccups due to compression of the nerves in the neck.
    • Intrapulmonary shunt: A rare condition where there is an abnormal connection between the pulmonary arteries and veins, which can cause hiccups among other symptoms.
