Glucose and Type 1 Diabetes

Definition: Glucose is a simple sugar that is found in most foods classified as carbohydrates. When these foods are eaten, the body breaks down the glucose and uses it for energy. For glucose to be properly used as fuel by the body, it must enter into cells. But glucose can't find its way into a cell without the help of the hormone insulin to act as a key for gaining access. Those with type 1 diabetes do not produce enough insulin. As a result, glucose concentrates in the blood and cannot get into the body's cells to provide energy, leaving the person with extreme fatigue. When this happens, the body breaks down fat instead of glucose in a way that produces ketones in the blood that can lead to serious and potentially life-threatening acute health problems. Prolonged blood glucose levels also leave the person at risk for a number of short and long-term health complications.
Also Known As: Dextrose
Glucose can be found in most foods containing carbohydrates, such as fruits, breads, cereals, vegetables and milk products.
