Hypoglycaemia






 The American Diabetes Association Workgroup on Hypoglycaemia  suggests the following classification and definitions of hypoglycaemia:


Severe hypoglycaemia


An event requiring assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions. These episodes may be associated with sufficient neuroglycopenia to induce seizure or coma. Plasma glucose measurements may not be available during such an event, but neurological recovery attributable to the restoration of plasma glucose to normal is considered sufficient evidence that the event was induced by a low plasma glucose concentration.


Documented symptomatic hypoglycaemia


An event during which typical symptoms of hypoglycaemia are accompanied by a measured plasma glucose concentration 70 mg/dl (3.9 mmol/l).


Asymptomatic Hypoglycaemia


An event not accompanied by typical symptoms of hypoglycaemia but with a measured plasma glucose concentration 70 mg/dl (3.9 mmol/l).


Since the glycaemic threshold for activation of glucagon and adrenaline secretion as glucose levels decline is normally 65-70 mg/dl (3.6-3.9 mmol/l) and since antecedent plasma glucose concentrations of  70 mg/dl (3.9 mmol/l) reduce sympathoadrenal responses to subsequent hypoglycaemia, this criterion sets the lower limit for the variation in plasma glucose in non diabetic, non pregnant individuals as the conservative lower limit for individuals with diabetes.
