What is the dawn phenomenon in type 2 diabetes and what can you do?
The aim of the study was to determine if the dawn phenomenon in type 2 diabetes can be predicted and quantified using simple and easily accessible glucose determinations.
More than 200 people with T2D underwent continuous glucose monitoring.The dawn phenomenon was quantified as the increment from the nocturnal glucose nadir to the pre-breakfast value.The preLD and preD values were compared with the nocturnal nadir.These values were not included in the pre-breakfast values.dawn values correlated with the differences obtained.The ROC curve was used to pick the optimal pre-meal value that best predicted a dawn phenomenon, set at a threshold of 20mg/dL.
The nocturnal nadir and dawn values were correlated with the pre-breakfast values.The correlations for the parameters averaged at preL and preD time points were the strongest.According to the ROC curve analysis, the dawn phenomenon at a threshold of 20mg/dL can be predicted.There was a relationship between dawn and pre-meal LD.
The dawn phenomenon can be predicted by the self-monitoring of preprandialglucose values at the three main mealtimes.
The dawn phenomenon is related to type 2 diabetes.
