What Is a Blood Glucose Level?

When it comes to maintaining your health, your blood glucose level is one of the most important readings in your body. Also known simply as blood sugar, blood glucose provides the fuel your body needs to power the brain, heart and muscles. A lot of the glucose in your body comes from the foods you eat, but some is produced by the liver and used as needed. Ideally, your blood glucose level remains stable throughout the day in a range of 80-99 mg/dL (milligrams of sugar per deciliter of blood), with temporary spikes occurring after you eat, followed by insulin-aided drops back into the normal range.

If blood glucose doesn’t move into your cells to provide energy, it could lead to a buildup of glucose in the bloodstream that is known as diabetes. On the other hand, if your blood glucose level drops too low between meals, this causes hypoglycemia, also a potentially dangerous health condition. If you suspect you have issues with either high or low blood sugar, it’s critical to monitor your blood glucose level.
