Hypoglycemia
Hypoglycemic symptoms can also occur when one is sleeping. Examples of symptoms during sleep can include damp bed sheets or clothes from perspiration. Having nightmares or the act of crying out can be a sign of hypoglycemia. Once the individual is awake they may feel tired, irritable, or confused and these may be signs of hypoglycemia as well.
Dopamine beta hydroxylase deficiency
Another commonly experienced symptom is hypoglycemia, which is thought to be caused by adrenomedullary failure. In looking at the cardiovascular system, a loss of noradrenergic control is seen as T-wave abnormalities on electrocardiogram. Prolactin is frequently suppressed by excessive dopamine found in the patient's central nervous system. Excess dopamine can also affect digestion, producing vomiting and inhibiting motor signaling to the GI tract.
