Could it be hyperammonemia? It could! - A Talk with Drs. Karen Eigen and George Diaz

Hyperammonemia presents a significant diagnostic challenge in the emergency department due to its nonspecific symptoms, such as vomiting, lethargy, and altered mental status. Dr. Karen Eigen and Dr. George Diaz emphasize that clinicians must maintain a high index of suspicion, particularly when patients exhibit recurrent, unexplained symptoms or aversive behaviors toward high-protein foods. Accurate testing is critical; clinicians must ensure free-flowing samples, avoid tourniquets, and process specimens on ice to prevent erroneous results. Because elevated ammonia levels can lead to rapid neurological deterioration and cerebral edema, early intervention—including dextrose administration and prompt consultation with genetics or nephrology—is essential. Identifying underlying triggers, such as viral syndromes or metabolic stressors, remains vital for preventing irreversible neurological damage in both pediatric and adult populations.
