What is blood sugar?
Blood sugar, also known as blood glucose, comes from the food you eat. Your body creates blood sugar by digesting some food into a sugar that circulates in your bloodstream.
Blood sugar is used for energy. The sugar that isn’t needed to fuel your body right away gets stored in cells for later use.
Too much sugar in your blood can be harmful. Type 2 diabetes is a disease that’s characterized by having higher levels of blood sugar than what’s considered within normal limits.
Unmanaged diabetes can lead to problems with your heart, kidneys, eyes, and blood vessels.
The more you know about how eating affects blood sugar, the better you can protect yourself against diabetes. If you already have diabetes, it’s important to know how eating affects blood sugar.
