Diagnostic Considerations

Important clinical criteria to consider in the evaluation of a child with hypoglycemia and suspected glycogen-storage disease type 0 (GSD-0) include (1) the presence or absence of hepatomegaly; (2) the characteristic schedule of hypoglycemia, including unpredictable, postprandial, short fast, long fast, or precipitating factors; (3) the presence or absence of lactic acidosis; (4) any associated hyperketosis or hypoketosis; and (5) any associated liver failure or cirrhosis.

The differential diagnosis also includes ketotic hypoglycemia. Patients with ketotic hypoglycemia have a normal response to glucagon in the fed state. Patients with glycogen-storage disease type 0 have normal-to-increased response to glucagon in the fed state, with hyperglycemia and lactic acidemia.
