  • Once the diagnosis has been made, the principal goal of treatment is to maintain an adequate glucose level and prevent hypoglycemia.[en.wikipedia.org]

  • In skeletal muscle, e.g., GSD 5, this can prevent proper muscle functioning, exercise intolerance and rhabdomyolysis.[knowledge.statpearls.com]
