Glucose (or Blood Sugar): It is the simplest type of sugar, used by the body's cells as a source of energy.
Diabetes mellitus: It is a chronic disease that affects the way the body’s cells receive glucose or the amount of insulin secreted by the pancreas; which leads to an abnormal high or low in blood sugar levels.
Pre-diabetes: It is the condition that affects people before they develop type 2 diabetes, so that the blood sugar level is higher than normal but not yet high enough for a diagnosis of type 2 diabetes. The early detection and treatment of pre-diabetes help restore normal blood glucose levels and prevent type 2 diabetes.
