Sweet Taste Dysgeusia in a Patient with Indapamide-Related Hyponatremia: Case Report and Review of the Literature.

Sweet taste dysgeusia is a rare symptom where patients experience all food as having a sweet taste. While its cause is still unknown, it has been increasingly reported in the setting of lung cancer and syndrome of inappropriate secretion of antidiuretic hormone-related hyponatremia. In this case report, we present what we believe to be the first case of sweet taste dysgeusia in a non-cancer context. We will briefly review and summarize all published cases describing this symptom and also reflect upon the nature of this condition focusing on the role of serum sodium levels in sweet taste receptor modulation.
