Hyponatremia is quite common in cancer patients, but the presentation as persistent hiccups is not common. Literature over hiccups development due to hyponatremia is quite scant. Hiccups are of various types, persistent hiccups are those that last more than 48 h and remains less than 1 month. Hiccups lasting more than 24 h require investigation for an underlying organic etiology, with hyponatremia included in the differential diagnosis. This paper discusses a carcinoma lip patient presented with the persistent hiccups and unconsciousness post-operatively. The patient was initially responded with trials of both metoclopramide and Ryle's tube insertion, but eventually, his hiccups resolved only after treatment of hyponatremia. Patient's clinical course and investigations suggest an etiology of syndrome of inappropriate antidiuretic hormone (SIADH) secretion behind the hyponatremia. Study suggested that SIADH linked hyponatremia should be considered in the differential diagnosis of cancer patients with refractory hiccups.
