There is wide variance among individuals in the fraction of insulin cleared by the liver (20%
to 80%). Hepatic insulin clearance is 67% lower in African Americans than European
Americans. Clearance is also lower in African American children 7–13 years of age. Lower
hepatic insulin clearance will result in peripheral hyperinsulinemia: this exacerbates insulin
resistance, which stresses the β-cells, possibly resulting in their ultimate failure and onset of
type 2 diabetes. We hypothesize that lower insulin clearance can be a primary cause of type …

Lower hepatic insulin clearance will result in peripheral hyperinsulinemia: this exacerbates insulin resistance, which stresses the β-cells, possibly resulting in their ultimate failure and onset of type 2 diabetes. We hypothesize that lower insulin clearance can be a primary cause of type 2 diabetes in at-risk individuals.
