I need clarification re: hypo/hyperglycemia. I understand it for what it is, just need clarification as to how it affects the body. For instance, I realize hyperglycemia is the resultant of high blood sugars and lack of insulin. furthermore, insulin converts glucose into glycogen for storage, so that it's not so high in the bloodstream. So, my question: is the problem in hyperglycemia r/t the high levels of glucose causing toxicity or the body needs insulin in order for cells to use said glucose, not just to convert into storage? the latter makes sense, since the body begins to breakdown ketones for cellular usage. as for hypoglycemia, my understanding is that there is not enough sugars/glucose for cells to use, creating hypoglycemic symptoms, esp neurologically wherein the brain cannot use fats and/or proteins for breakdown to get energy. having said that, the body can convert the glycogen back to glucose for uptake. if its insulin r/t, is it because the insulin is simply converting any glucose back to glycogen? making there be no glucose available for cellular metabolism? I feel like I have the fundamental understanding, but want to grasp the "big picture" of a very real disease that is making so many lives difficult. Thanks.
