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.
Hypoadrenocorticism in dogs
Symptoms of hypoadrenocorticism can include vomiting, diarrhea, lethargy, lack of appetite, tremors or shaking, muscle weakness, low body temperature, collapse, low heart rate, and pain in the hind quarters. Hypoglycemia can also be present, and initially may be confused with seizure disorders, insulin-secreting pancreatic tumor (insulinoma), food poisoning, parvovirus enteritis, gastric volvulus, spinal or joint problems, earning hypoadrenocorticism the nicknames of "the Great Mimic" and "the Great Imitator". It is possible not to see any signs of the disease until 90% of the adrenal cortex is no longer functioning.
