Types of hypoglycaemia
Mild hypoglycaemia
Severe hypoglycaemia
Nocturnal hypoglycaemia
To align hypoglycaemia terminology in clinical trials and encourage appropriate responses in clinical practice, the IHSG has developed the following definitions:1
Level 1
A glucose alert value of 3.9 mmol/L (70 mg/dL) or less. This often doesn’t need to be reported routinely, depending on the purpose of the clinical study.
Level 2
A glucose alert value of <3.0 mmol/L (<54 mg/dL) is sufficiently low and indicates serious, clinically important hypoglycaemia.
Level 3
As defined by the ADA, severe hypoglycaemia indicates severe cognitive impairment requiring external assistance for recovery.
