There is a diference both in the hbA1c and the readings on the glucose meters depending upon the hematcrit, or the number of erythrocytes per unit volume. The meters are calibrated to a specific number of cells per unit volume, which is a compromise between the readings of the male and the female.
Males have a hematcrit of around 46 and females, because of menstrual bleeding, often end up between 36 and 38.
Thus female tend to have slightly higher glucose readings than they actually have and men may have a slightly lower reading. The literature suggests that runs about four-five points.
It makes sense to know your hematocrit. For someone with hemorhoids, for example, the hematcrit may drop down into the twenties, and the readings on the meter will not be accurate.
I would concur with Zoelula that type 2 is more likely to cause cardiac problems in the short run. In the long run, uncontrolled diabetes is dangerous no matter what kind it is.
