Approach to acute hypoglycemia

Hypoglycemia is a common clinical disorder with a large number of possible causes. Hypoglycemia is defined for the clinician as a diagnosis rather than a symptom complex. Hypoglycemic states can be characterized initially as medication associated, fasting, or postprandial. An approach based on the physiologic mechanisms that support euglycemia is useful to sort through the differential diagnosis of hypoglycemia for both adults and children.
