Glucose levels are usually lowest in the morning, before the first meal of the day, and rise after meals for an hour or two by a few millimoles per litre. Abnormal persistently high glycemia is referred to as hyperglycemia; low levels are referred to as hypoglycemia.
Glucose concentrations of both <3.0 mmol/l and <2.8 mmol/l cause defective glucose counterregulation and impaired awareness of hypoglycaemia, the core components of hypoglycaemia-associated autonomic failure in diabetes [5].

Glucose concentrations of both <3.0 mmol/L (<54 mg/dL) and <2.8 mmol/L (<50 mg/dL) cause defective glucose counterregulation and impaired awareness of hypoglycemia, the core components of hypoglycemia-associated autonomic failure in diabetes (5).

This particular example perfectly highlights why At Low Glucose Concentrations 3 Mm is so captivating.

Low blood sugar, a.k.a. hypoglycemia, happens when the level of glucose in your blood drops below normal, according to the National Institutes of Health. This is a topic that actually comes up quite a bit for me with patients and clients, Jessica Cording, a New York-based R.D., tells SELF.
