@Equestrianforlife7xo,
I may have just spread some confusion. Hypoglycemia means low blood sugar - for whatever reason. Now, I vaguely understand that some people have it as a chronic condition. I'm not familiar with that, at all. Many people with diabetes, including myself get into it on a temporary condition. It can come from going too long without eating, it can come from exercising on an empty stomach, alcohol can cause it in
some people, and for those who are insulin dependent, an miscalculation of doseage can cause serious hypoglycemia.
Now, in a person with normal metabolism, which I suspect includes you, it almost never happens. During moderate exercise like a comfortable walking pace, body fat metabolises into blood sugar, and there is no problem. In extreme excerise, glycogen stored in the muscle cells and the liver is converted to blood sugar. This is a very fast process, and blood sugar remains pretty much within a normal range. By the way, if you are exercising hard and run out of glycogen reserves, you stop. You will stop right then and there. This will probably never happen to either one of us. It has happened with a few professional athletes, and is a time when pure glucose is needed. If you're really interested, this is what is known as 'hitting the wall' or 'bonking'.
Hyperglycemia is the exact opposite. Blood sugar is above normal range because it isn't being used for immediate energy, and stays in the blood stream because it isn't being stored as fat. So far as I know, glycogen is only produced as a result of exercise. Again, so far as I know, chronic hyperglycemia is another way of saying diabetes.
Always keep in mind that anything you can digest can, and often is converted into sugar. Carbohydrates are just the fastest.
