A common cause of hyperglycemia in people with diabetes is the dawn phenomenon. (medicalnewstoday.com)
Not all high blood sugar levels in the morning are the result of the dawn phenomenon, however. (medicalnewstoday.com)
Waking up during the night and testing blood sugar can be an effective way to determine whether these peaks are a result of the dawn phenomenon or down to other causes. (medicalnewstoday.com)
A linear model was used to fit the optimal linear formula of the magnitude of dawn phenomenon (ΔDawn) and self-monitoring of blood glucose values. (hindawi.com)
Dawn phenomenon could be partly assessed by blood glucose self-monitoring in Chinese people with T2DM using the abovementioned formula. (hindawi.com)
The incidence of dawn phenomenon was similar among patients in different oral antidiabetic drug groups. (hindawi.com)
Continuous glucose monitoring system (CGMS), which has been widely used for decades, effectively improves the qualitative and quantitative detection of dawn phenomenon. (hindawi.com)
Using CGMS, dawn phenomenon is determined using the absolute differences between the nocturnal glucose nadir and the prebreakfast glucose values at a threshold of 20 mg/dL [ 2 - 4 ]. (hindawi.com)
showed that the approximate impact of the dawn phenomenon on HbA 1c level was 0.4%, while its impact on averaged 24 h mean glucose concentrations was 12.4 mg/dL [ 3 ]. (hindawi.com)
Although dawn phenomenon is not considered a main control target in the management of T2DM, we should not ignore it. (hindawi.com)
5 ] published a simple method for assessing and quantifying the presence of the dawn phenomenon using SMBG. (hindawi.com)
Y (magnitude of dawn phenomenon, mg/dL) = 0.49 × (prebreakfast glucose average prelunch and predinner glucose, mg/dL) + 15 (mg/dL) [ 5 ]. (hindawi.com)
In addition, receiver operating characteristic curve analysis demonstrated that prebreakfast glucose minus the average prelunch and predinner cutoff value of 10 mg/dL could predict the dawn phenomenon at a threshold of 20 mg/dL [ 5 ]. (hindawi.com)
This formula might be a practical, feasible, and reliable method for evaluating dawn phenomenon using SMBG. (hindawi.com)
