Which electrolyte abnormality is commonly found in anorexia nervosa?

Hypokalaemia is commonly found in anorexia nervosa due to several factors associated with the condition. Individuals with anorexia often experience significant nutritional deficiencies, which can include inadequate potassium intake. Additionally, behaviors such as excessive exercise, vomiting, and misuse of laxatives can further deplete potassium levels in the body.

Low potassium can lead to a range of serious health issues, including cardiac arrhythmias, muscle weakness, and, in severe cases, can even be life-threatening. The condition is frequently exacerbated by the physiological stress on the body caused by starvation and malnourishment, which can alter various electrolyte balances, but hypokalaemia remains particularly prevalent.

Thus, the recognition of hypokalaemia in patients with anorexia nervosa is crucial in both diagnosis and management, ensuring appropriate care is provided to address this potentially dangerous electrolyte imbalance.
