Hypoglycemia

Predisposing factors

Hypoglycemia is the result of a mismatch between insulin, food and exercise

  • Altered routine (missed or erratic meals, changes in physical activity, alterations or errors in insulin dosage or absorption)
  • Younger age (<6 years)
  • Lower HbA1c
    [see below]
  • Total deficiency of endogenous insulin
  • Antecedent hypoglycemic episodes
  • Hypoglycemic unawareness
  • Defective glucagon and catecholamine counter-regulation (longer duration)
  • Alcohol ingestion

Good evidence now exists that in diabetes centers where excellent metabolic control is achieved (with lower mean HbA1c levels) the frequency of severe hypoglycemia may be less than in some other centers achieving less satisfactory levels of control
