Prediabetes is a term used for individuals with impaired fasting glucose (IFG) or impaired glucose tolerance (IGT). IGF and IGT are associated with obesity (particularly belly fat abdominal or visceral obesity). Your body uses glucose as its primary source of energy. Insulin – the hormone produced by the pancreas – is responsible for taking sugar from your blood to your cells to use for energy. In someone who has prediabetes, this mechanism of sugar utilization is not working properly; sugar in the blood stays elevated, but not high enough to have full blown diabetes.
