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.
Diabetic coma
Nonketotic hyperosmolar coma usually develops more insidiously than diabetic ketoacidosis because the principal symptom is lethargy progressing to obtundation, rather than vomiting and an obvious illness. Extremely high blood sugar levels are accompanied by dehydration due to inadequate fluid intake. Coma occurs most often in patients who have type 2 or steroid diabetes and have an impaired ability to recognize thirst and drink. It is classically a nursing home condition but can occur in all ages.
