What is Blood Glucose?

Blood glucose, measured in milligrams per deciliter (mg/dL), refers to the amount of glucose present in the bloodstream. Glucose is a simple sugar that comes from the foods we eat and is the primary source of energy for cells. The pancreas plays a key role in maintaining healthy blood glucose levels through production of insulin, which facilitates the movement of glucose from blood into cells. Insulin signals cells to absorb glucose from blood for energy needs. If insulin is deficient or cells are resistant, glucose builds up in blood resulting in harmful effects.

Regulation of Blood Glucose

Veterinary Blood Glucose are tightly regulated by several hormones and enzymes in the body. After a meal, food is broken down into glucose that enters the bloodstream. The pancreas automatically detects rising blood glucose and releases the hormone insulin. Insulin allows cells to take up glucose from blood for energy needs of tissues. At the same time, glucagon hormone released by the pancreas signals the liver to break stored glycogen into glucose to maintain normal blood sugar levels between meals. This back-and-forth communication ensures blood glucose remains within a normal range.
