Hyperemesis gravidarum, defined as persistent vomiting in pregnancy causes weight loss, dehydration, and ketosis and affects 1% of the pregnant population (Neill et al. 2003). Refeeding syndrome can be denned as potentially fatal shifts in fluids and electrolytes that may occur in malnourished patients receiving artificial refeeding (Mehanna et al. 2008). We present a case of severe hyperemesis complicated by development of refeeding syndrome following nasojejunal feeding. This syndrome is characterised by life-threatening micronutrient deficiencies, fluid and electrolyte imbalance and disturbance of organ function (NICE 2006).
