So hyperglycemia is the opposite of hypoglycemia in the sense that hyper means we have a very high concentration of glucose inside our blood. Now, how exactly does this actually come about? How do we obtain a high concentration of glucose inside our blood? Well, let's imagine that our beta cells, for one reason or another, aren't able to produce enough insulin. And that means we have a low amount of insulin inside our blood. And so if we don't have enough insulin, not too many of those glucose molecules will be transported into the cells from our blood plasma and that will basically create a hyperglycemia condition.
