The prevalence of impaired perception of the onset of symptoms of hypoglycemia increases with the duration of insulin treatment. Counter regulatory deficiency is closely associated with impaired awareness of hypoglycemia, suggesting a common pathogenetic mechanism within the brain.

Severe hypoglycemia is any episode requiring the assistance of another person for recovery. Severe hypoglycemia can

result in serious morbidity and mortality in insulin treated patients. Exercise induced hypoglycemia occurs in people with well controlled insulin treated diabetes because of hyperinsulinaemia and the absence of the capacity to decrease secretion of endogenous insulin.
Nocturnal hypoglycemia does not usually waken the sleeping patient. But on enquiring, patient may tell about poor quality of sleep, morning headaches, hangover, chronic fatigue and vivid dreams.
