Association between BMI and risk of severe hypoglycaemia in type 2 diabetes.

BMI and severe hypoglycaemia were found to be inversely associated. Thus, those who fall into the category of having low BMI and high risk of severe hypoglycaemia should be warned about the risk of having a hypoglycaemic event and be properly informed about hypoglycaemia to minimize the risk of fatal hypoglycaemia-related outcomes.
