abstractpoorly controlled diabetes mellitus ( dm ) is associated with the development of long - term micro- and macro - vascular complications . 
 the predominant focus of anti - diabetic therapy has been on lowering glycosylated haemoglobin levels , with a strong emphasis on fasting plasma glucose ( particularly in type 2 dm ) . 
 there is considerable evidence indicating that post - meal hyperglycaemic levels are independently associated with higher risks of macro - vascular disease . 
 although some have identified mechanisms which may account for these observations , interventions which have specifically targeted postprandial glucose rises showed little or no effect in reducing cardiovascular risk . clinical experience and some recent studies suggest acute hyperglycaemia affects cognition and other indicators of performance , equivalent to impairment seen during hypoglycaemia . in this brief report , we evaluated the published studies and argue that acute hyperglycaemia is worth investigating in relation to the real - life implications . in summary , 
 evidence exists suggesting that acute hyperglycaemia may lead to impaired cognitive performance and productivity , but the relationship between these effects and daily activities remains poorly understood . 
 further research is required to enhance our understanding of acute hyperglycaemia in daily life . 
 a better appreciation of clinically relevant effects of acute hyperglycaemia will allow us to determine whether it needs to be addressed by specific treatment.fundingnovo nordisk a / s sborg , denmark.electronic supplementary materialthe online version of this article ( doi:10.1007/s13300 - 015 - 0126-y ) contains supplementary material , which is available to authorized users .
