Background
The glucose in the blood is called blood glucose. Most of the energy required for the cellular activities of tissues in the body comes from glucose, so blood glucose must be kept at a certain level to maintain the needs of organs and tissues in the body. The fasting blood glucose concentration of normal people in the early morning is 80-120 mg%. Fasting blood glucose concentrations in excess of 130 mg% are termed hyperglycemia. If the blood sugar concentration exceeds 160-180 mg%, a part of glucose is discharged with urine, which is diabetes. Diabetes is a group of metabolic diseases characterized by hyperglycemia. Hyperglycemia is caused by a defect in insulin secretion or an impaired biological action thereof, or both. Diabetes mellitus is a long-standing hyperglycemic condition that results in chronic damage to, and dysfunction of, various tissues, particularly the eye, kidney, heart, blood vessels, nerves.
