Reactive hypoglycemia tolerance test nor a breakfast test is effective; instead, a hyperglucidic breakfast test or ambulatory glucose testing is the current standard. The body requires a relatively constant input of glucose, a sugar produced upon digestion of carbohydrates, for normal functioning. Glucagon and insulin are among the hormones that ensure a normal range of glucose in the human body. Upon consumption of a meal, blood sugar normally rises, which triggers pancreatic cells to produce insulin. This hormone initiates the absorption of the just-digested blood glucose as glycogen into the liver for metabolism or storage, thereby lowering glucose levels in the blood.
Adenosine monophosphate deaminase deficiency type 1 recycled back into glucose or burned by other cells in the body. However the newly generated glucose is made available to all cells in the body, not just to muscle cells. The ability of the body to assimilate lactate may also be diminished, if working muscle cells cannot take up glucose from blood, due to myophosphorylase maintaining a higher concentration of it inside loaded cells, and if liver has already filled its glycogen stores up to capacity. So, ultimately, in this state, working muscle cells are destined to lose all glycogen. AMP breakdown to adenosine in this state is minor,
