GSD I patients typically present with an enlarged liver from non-alcoholic fatty liver disease as the result of this glycogen buildup.[1] Other functions of the liver and kidneys are initially intact in GSD I, but are susceptible to a variety of other problems.[vague] Without proper treatment, GSD I gives rise to chronic low blood sugar, which can result in derangements including excessive levels of lactic acid and abnormally high levels of lipids in the bloodstream. Frequent feedings of cornstarch or other carbohydrates are the principal treatment for all forms of GSD I.
