One of the underlying causes of hypoglycemia is a fatty liver and depleted glycogen stores. Glycogen is the stored form of sugar in the liver and muscles. The liver is responsible for maintaining blood sugar levels between meals by converting glycogen back into glucose. The glucose is then released back into the bloodstream to sustain blood sugar levels and prevent hypoglycemia. When a liver becomes fatty, glycogen stores become depleted, causing someone to be more prone to hypoglycemia. ~ Didem
