What happens to blood sugar levels after you eat

You've probably heard the term "blood sugar" and heard people talk about whether theirs is high or low. "Hyperglycemia" just means high blood sugar; hypoglycemia means low blood sugar. Your body works best when your blood sugar levels stay within a certain range. Too low, and your energy and ability to think clearly will crash; too high, and all kinds of things start to go out of whack. Long-term high levels -- which happens when you have diabetes -- can do permanent damage in your smaller blood vessels: feet, hands, and eyes.

Here's a 9-minute video from Khan Academy which explains -- in a very simplified manner - what happens to your glucose (blood sugar) levels after you eat. And how the blood sugar levels in a diabetic differ from those in a healthy individual.
