4. Other conditions
Erythroblastosis fetalis causes an abnormal increase in the number of pancreatic beta cells and increases in the secretion of insulin.17 Other conditions that increase the production of insulin include: Beckwith-Weidemann syndrome, insulin- producing tumors, maternal tocolytic therapy and exchange transfusion with blood high in glucose content. Some risk factors are transient; others like familial hyperinsulinism and inborn errors of metabolism are prolonged.
