  • Older age
  • Previous episodes of severe hypoglycaemia
  • Loss of hypoglycaemic awareness
  • Long duration of diabetes
  • Erratic carbohydrate intake e.g. irregular meals, low carbohydrate diet
  • Renal impairment
  • Tight glycaemic control e.g. HbA1c < 48 mmol/mol

  • Causes of hypoglycaemia
  • Missed meals
  • Exercise/physical activity
  • Alcohol
  • Too rapid an increase in insulin and/or sulfonylureas
