What laboratory finding might you expect in a patient with anorexia nervosa?

In a patient with anorexia nervosa, hypokalemia is a common laboratory finding due to several factors associated with the disorder. Individuals with anorexia often exhibit severe dietary restrictions, leading to inadequate intake of essential nutrients and electrolytes, including potassium. Additionally, behaviors such as purging, which some patients may engage in to control weight, can result in significant loss of potassium and related electrolytes, further contributing to hypokalemia.

Hypokalemia can have serious physiological consequences, impacting cardiac function and leading to arrhythmias. Recognition of this electrolyte imbalance is crucial in the management of patients with anorexia nervosa, as it can be a marker of the severity of the disorder and a potential indicator of the need for urgent medical intervention. Monitoring electrolytes and managing their imbalances is an essential component of the treatment plan for affected individuals.
