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.
Hyperinsulinemia
There are often no visible symptoms of hyperinsulinemia unless hypoglycaemia (low blood sugar) is present.
