INS and type 1 diabetes mellitus: Greater daytime sleepiness in patients with a shorter duration of T1DM and higher levels of HbA1c can be explained by the inexperience of caregivers with regard to blood glucose monitoring and insulin applications, the need for a greater number of capillary blood glucose measurements to adjust insulin therapy and the concern with the occurrence of nocturnal hypoglycemia, which leads to more frequent nocturnal awakenings.
