Hiccup is an intermittent spasmodic contraction of the diaphragm, which is usually a benign and self-limiting condition. However, persistent hiccups may indicate a more sinister underlying pathology. Hiccups have been reported in the literature as an unusual manifestation in hyponatremia. Some literature had linked the severity of hiccups to the level of serum sodium. Present case report is of persistent hiccups, seen in a 60-year-old male patient who presented with serum sodium of 100 mmol/L. Apart from the troublesome hiccups, he had associated dizziness, unsteady gait and poor oral intake. His hiccups resolved after correction of serum sodium above 124 mmol/L. The dose-response relationship between hyponatremia and hiccups vary in different individuals. A fluoroscopic examination can be considered in cases of hiccups or hyponatremia to conclude the association between both.
