Glucose, a form of sugar, is the body’s main fuel. Hypoglycemia, or low blood sugar, occurs when blood levels of glucose drop too low to fuel the body’s activity.
Carbohydrates (sugars and starches) are the body’s main dietary sources of glucose. During digestion, the glucose is absorbed into the blood stream (hence the term “blood sugar”), which carries it to every cell in the body. Unused glucose is stored in the liver as glycogen.
Hypoglycemia can occur as a complication of diabetes, as a condition in itself, or in association with other disorders.
