How Food Affects Your Blood Glucose

Whether you have type 1 or type 2 diabetes, what, when, and how much you eat all affect your blood glucose. Blood glucose is the main sugar found in the blood and the body's main source of energy.

If you have diabetes (or impaired glucose tolerance), your blood glucose can go too high if you eat too much. If your blood glucose goes too high, you can get sick.

Your blood glucose can also go too high or drop too low if you don't take the right amount of diabetes medicine.

If your blood glucose stays high too much of the time, you can get heart, eye, foot, kidney, and other problems. You can also have problems if your blood glucose gets too low (hypoglycemia).

Keeping your blood glucose at a healthy level will prevent or slow down diabetes problems. Ask your doctor or diabetes teacher what a healthy blood glucose level is for you.
