While the exact cause of hypoglycemic unawareness is still under research, it is thought that these individuals progressively begin to develop fewer adrenergic-type symptoms, resulting in the loss of neuroglycopenic-type symptoms. Neuroglycopenic symptoms are caused by low glucose in the brain, and can result in tiredness, confusion, difficulty with
