The initial presentation is most often characterized by abdominal distension and failure to thrive. Patients may present with hypoglycemic seizures or coma. [9]

Global muscle weakness is not a typical feature of von Gierke disease. Schwahn et al found height, weight, bone mass, and grip force decreased in one group of GSD 1a patients. [10]  Older patients may give a history of kidney stonesgout, or pancreatitis.

Patients may have delayed puberty. Intellectual development may be diminished, especially in patients who have experienced coma. [9]

A prospective study by Melis et al found that GSD Ia patients had a higher prevalence of insulin resistance and metabolic syndrome. [11]
