| I know of two diabetics who died from low blood sugars.
If you have frequent lows, they reduce your liver's ability to release glucagon. The glycogen stores and the hormones used to release glucose can both become depleted.
If you've had any alcohol, even one or two drinks, that can also reduce your liver's ability to react to a low blood sugar.
I am a long-distance runner, and that can also result in depleted glycogen.
I'm not trying to say that you should always be terrified of having low blood sugars, but I would hate for anyone to read this forum and think it's not dangerous, potentially lethal, to have your blood sugar go extremely low. |
