Wernicke's encephalopathy (WE) is a potentially reversible yet serious 
neurological manifestation caused by vitamin B1(thiamine) deficiency. It is 
commonly associated with heavy alcohol consumption. Other clinical associations 
are with hyperemesis gravidarum (HG), starvation, and prolonged intravenous 
feeding. Most patients present with the triad of ocular signs, ataxia, and 
confusion. It can be associated with life-threatening complication like central 
pontine myelinolysis (CPM). We report two cases of WE following HG, with two 
different outcomes.
