What are ammonia levels cirrhosis?

Results: Blood ammonia correlated positively with breath ammonia in patients with cirrhosis. Breath ammonia levels were significantly higher in cirrhotic patients (0.745 ppm) than in controls (0.278 ppm), and higher in cirrhotic patients with hyperammonemia (0.997 ppm) than in those without (0.558 ppm).

Can you recover from high ammonia levels?

Treatment options to decrease a high blood ammonia level include: Elimination of protein intake for neonates: Reduction of protein intake may treat newborns with inborn metabolic causes of hyperammonemia who experience coma.
