Hyperammonemia

Hyperammonemia is a critical metabolic condition characterized by dangerously elevated levels of ammonia in the blood due to impaired hepatic clearance or excessive nitrogenous production It affects both pediatric and adult populations, commonly arising from inborn errors of metabolism such as urea cycle disorders, advanced liver disease, portosystemic shunting, or severe catabolic stress Clinically, it presents with progressive neurological impairment ranging from lethargy, vomiting, and behavi...
