Bulimia nervosa: The Daily PANCE Blueprint

Which of the following laboratory abnormalities is most commonly noted in bulimia nervosa?

A. Hypokalemia
B. Glycosuria
C. Metabolic acidosis
D. Hyperalbuminemia
E. Hypoglycemia

Answer and topic summary

The answer is A. Hypokalemia

In bulimia nervosa, episodes of binge eating are typically followed by purging behaviors such as vomiting or the use of laxatives. These actions can lead to significant electrolyte imbalances, particularly hypokalemia. Hypokalemia results from the loss of potassium through vomiting and laxative use, which depletes the body of this essential electrolyte, often causing muscle weakness, cardiac arrhythmias, and fatigue.
