Hypoglycemia - Definition
Hypoglycemia (pronounced HI-po-gli-seem-ee-ah) means low blood sugar. The main fuel used by cells to produce energy is a type of sugar called glucose. Glucose is carried to cells in the bloodstream. In that form, glucose is often referred to as "blood sugar." Cells need a minimum amount of glucose to function properly. When there is not enough glucose in the blood to meet those needs, the condition known as hypoglycemia develops.
