Which laboratory finding is commonly associated with anorexia nervosa?

In the context of anorexia nervosa, hypochloremia is commonly observed due to the significant disruptions in electrolyte balance that can occur with restricted food intake and potential purging behaviors, such as vomiting or excessive intestinal losses. Anorexia nervosa often leads to metabolic imbalances, primarily because individuals may not consume adequate nutrition or fluids. Hypochloremia, which refers to low chloride levels in the blood, can occur as the body loses chloride through gastric secretions, particularly in cases where there are concurrent vomiting episodes or in the absence of proper dietary intake.

Additionally, the physiological stress from starvation can result in electrolyte disturbances, including reduced chloride levels. This finding is consistent with the body's response to malnutrition, which can lead to alterations in the fluid and electrolyte homeostasis. Thus, recognizing hypochloremia can be a critical part of the clinical evaluation in individuals with anorexia nervosa, helping to inform treatment strategies and monitor the patient’s physical health during recovery.
