what is blood sugar or blood glucose?

Blood sugar level also known as blood glucose level is the amount of sugar in a person’s blood. Blood sugar or glucose is a crucial unit of the body and serves as the primary source of energy. It is crucial to the normal functioning of varied tissues and most importantly the brain. Glucose levels are low in the morning before the first meal of the day and rises after having a meal. The blood glucose level is tightly regulated to maintain constant level in the body at all time. Continuous high levels of blood sugar are known as hyperglycaemia and low levels are referred to as hypoglycaemia.  Diabetes is the result of persistent hyperglycaemia.
