Second-Trimester Fetal Loss in a Patient With Hyperemesis Gravidarum Complicated by Refeeding Syndrome.

Abstract

Refeeding syndrome is a rare constellation of electrolyte abnormalities after reintroduction of glucose during an adaptive state of starvation and malnutrition, resulting in fluid shifts, end-organ damage, and, potentially, death. We present a case of fetal death in a patient with hyperemesis gravidarum complicated by refeeding syndrome. A 32-year-old obese, multigravid patient was admitted at 16 weeks of gestation with hyperemesis gravidarum and laboratory abnormalities concerning for refeeding syndrome after consuming a sugar-rich beverage. She was admitted to the hospital for electrolyte and fluid repletion; however, on hospital day 2, fetal death was diagnosed. Refeeding syndrome is a potentially fatal complication of hyperemesis gravidarum. Caution should be taken when reintroducing glucose during prolonged states of malnutrition to prevent the development of refeeding syndrome.
