[Hiccups, not always unremarkable].

Hiccups are most often benign and of short duration. However, they may also be persistent (superior to 48h) or even refractory (superior to 1 month). In such cases, they markedly alter the quality of life and can lead to severe impairment of health. We here review hiccups pathophysiology, etiologies, work up and treatment. We suggest that hiccups should be considered as a non-epileptic myoclonic movement disorder.
