Overview

Teresa A. Hillier, MD, MS, was an endocrinologist and distinguished investigator whose research included diabetes, gestational diabetes, metabolic disease and osteoporosis. She was lead author of the 1999 American Journal of Medicine experiment that re-evaluated the sodium correction factor during acute hyperglycaemia and reported 2.4 mmol/L per 100 mg/dL as the better overall estimate in that study.

Experimental study in six healthy subjects reporting a mean overall sodium change of 2.4 mmol/L per 100 mg/dL glucose change and a non-linear relationship at very high glucose concentrations; 2.4 is presented by MedMaths as the study's overall estimate, not a universal constant.
