Analysis of Electrolyte Abnormalities in Adolescents and Adults and Subsequent Diagnosis of an Eating Disorder
In this population-based case-control study, the investigators found that outpatient electrolyte abnormalities may serve as a precursor to future eating disorder diagnoses.
Electrolyte abnormalities commonly occurred well ahead of the time at which an eating disorder diagnosis was made.
Hypokalemia was the most common electrolyte abnormality identified while hyponatremia, hypernatremia, hypophosphatemia, and metabolic alkalosis were the most specific for a subsequent eating disorder diagnosis.
These results suggest that incidentally discovered electrolyte abnormalities may serve to identify individuals who may benefit from targeted screening for an underlying eating disorder. Ultimately, this may allow for more timely diagnosis and intervention to mitigate the negative impact that eating disorders have on patient morbidity, mortality, and quality of life.
