|Clinical Utility||Glucose comes from carbohydrate foods. It is the main source of energy used by the body. Hypoglycemia - a condition characterized by a drop in blood glucose to a level where first it causes nervous system symptoms (sweating, palpitations, hunger, trembling, and anxiety), then begins to affect the brain (causing confusion, hallucinations, blurred vision, and sometimes even coma and death).
