Hypoglycaemia – What is hypoglycaemia

Hypoglycaemia occurs when a person’s blood glucose level drops too low as a side effect of taking insulin or certain diabetes medications. Hypoglycaemia needs to be managed immediately in order to avoid the blood glucose level from dropping even lower. You may hear hypoglycaemia commonly referred to as a ‘hypo’ or a low blood glucose level.
