A top headline lately has been that of a diabetic woman who killed eight people in New York in a tragic car accident. It sounds like she may have been drunk and high on marijuana, although the family is insisting it was complications from her diabetes.
Regardless of which it is, this is a good example of why diabetics need to be careful about driving when they could be suffering from low blood sugar. My first doctor wanted me to always check my blood sugar before getting behind the wheel. He had a scary story about one of his patients passing out at the wheel and ending up being paralyzed in a terrible accident.
Although admittedly I don't do check my sugar every single time, I can also say with absolute certainty that I feel it when I'm crashing, and I check if I have any of the symptoms. Hypoglycemia unawareness is a real problem, and one I hope I never develop.
Anyway, it's better to be safe than sorry — if you have a track record of not feeling low sugars, or if you feel like you might be crashing, check your blood glucose first and don't get behind the wheel until it is safe to drive!
