Which is listed as a comorbidity related to disordered eating associated with sudden death?

• A. Amenorrhea
• B. Anemia
• C. Dysmenorrhea
• D. Electrolyte abnormalities

Answer: (C)

Electrolyte disturbances are the key risk factor linking disordered eating to sudden death in athletes. When someone with disordered eating loses fluids and electrolytes through vomiting, purging, laxatives, diuretics, or dehydration, levels of potassium, calcium, and magnesium can become severely imbalanced. These imbalances disrupt the heart’s electrical system, increasing the risk of dangerous arrhythmias and potentially sudden death, especially during exercise. Other issues may appear with disordered eating, but they don’t directly drive the fatal rhythm disturbances. Amenorrhea is a sign of low energy availability, not a direct cause of sudden death. Dysmenorrhea is unrelated to cardiac risk in this context. Anemia can reflect poor nutrition but doesn’t have the same immediate impact on cardiac conduction as electrolyte abnormalities.
