Sometimes known as "borderline diabetes", people with IGT have ineffective blood glucose regulating ability, but the degree of this has not reached the
level established for the diagnosis of diabetes. It is estimated that 25% of people with IGT eventually progress to diabetes, but most do not.
People with IGT do have increased risk
for cardiovascular diseases similar to people with Type 2 diabetes. The primary management of this IGT is not blood glucose control, however. The emphasis of treatment is lowering blood
lipids (cholesterol and triglycerides), controling blood pressure and weight management.
