Glucose the body’s major source of energy. It is made from the metabolizing of carbohydrates and used to power cellular activity in the muscles, brain and other organs. Glucose reaches these cells via the bloodstream, where the hormone insulin allows glucose to move from the bloodstream into cells. Blood glucose is often called “blood sugar.”
When a person has type 2 diabetes, their body is no longer able to effectively manufacture or use insulin. As a result, glucose is unable to move from the bloodstream into cells the way it should, and blood sugar levels become much higher than normal.
Elevated blood sugar levels can damage the body in a number of ways.
