Glucose - Random


Glucose is a sugar that acts as the body's main source of energy. Most of the body's cells require glucose for energy production. The brain and nervous system cells can only function when glucose levels in the blood remain within a certain range.

The hormone insulin controls the transport of glucose into the body's cells to be used as energy. We cannot live without glucose or insulin and they must be in balance. It is important that blood glucose levels remains fairly stable as severe high or low levels can be life threatening.

What might a low result mean?

Low glucose levels are often in seen in those with hypothyroidism, liver disease and hypopituitarism.

What might a high result mean?

Slightly increased glucose levels may be seen in those with impaired glucose tolerance which if left unaddressed, can lead to type 2 diabetes. High glucose levels often indicate diabetes but other conditions such as hyperthyroidism and long term kidney disease can also cause high glucose levels in the blood.
