  1. A. Introduction. A hiccough is an inspiratory sound caused by the abrupt closure of the glottis in the setting of rhythmic spasm of the diaphragm and respiratory muscles.

  2. B. Causes of Hiccoughs. Hiccoughs may be caused by a wide variety of conditions that share one thing in common—they involve the reflex arc shown in Figure 84.1. Causes can be classified as peripheral (i.e., involving the vagus or phrenic nerves and/or structures adjacent to the diaphragm) or central.

    Figure 84.1 The many causes of hiccough involve this reflex arc in some way.

    • MNEMONIC: Common Causes of Hiccoughs (Also Known as Singultus) (“Singultus”)

    • Surgery (following abdominal, thoracic, or neck surgery)

    • Infection of structures adjacent to the diaphragm (e.g., lower lobe pneumonia, subphrenic abscess, peritonitis)

    • Nervous system disorders (e.g., stroke, meningitis, brain tumor, multiple sclerosis)

    • Gastric distention (a very common cause)

    • Uremia

    • Low serum calcium, sodium, or potassium

    • Tumor of the pancreas

    • Ψ‎chiatric disorders

    • Steroids and other drugs (e.g., alcohol, benzodiazepines, barbiturates)

  3. C. Treatment. Treating the underlying disorder is the best course of action.

    1. a. Several benign strategies to relieve hiccoughs have been anecdotally successful, though limited evidence is available to support these interventions (e.g., drinking water, swallowing saliva).

    2. b. Pharmacologic therapy (e.g., chlorpromazine, metoclopramide, or baclofen) may be used if benign strategies fail.

    3. c. Testing or imaging are rarely indicated for hiccoughs unless clinical concern of a systemic cause of malignancy exist.
