What is glucose? What is glucose used for?

Glucose also known as dextrose is a simple sugar (monosaccharide) that is used to increase the level of blood sugar (glucose) when the level falls too low (hypoglycemia). Glucose in this form increases the level of the blood sugar, so it is a glucose-elevating agent. Other glucose-elevating agents are diazoxide (Proglycem) and glucagon.

Glucose is the primary fuel used by most cells in the body to generate the energy that is needed to carry out cellular functions. When glucose levels fall to hypoglycemic levels, cells cannot function normally, and symptoms develop such as nervousness, cool skin, headache, confusion, convulsions, or coma. Ingested glucose is absorbed directly into the blood from the intestine and results in a rapid increase in the blood glucose level.
