Which dietary modification is advisable for a patient with elevated ammonia levels?

Reducing protein intake is a critical dietary modification for patients with elevated ammonia levels, often associated with conditions such as liver disease or hepatic encephalopathy. The rationale behind this approach stems from the fact that protein metabolism produces ammonia as a byproduct. When the liver is compromised, its ability to convert ammonia into urea for excretion diminishes, leading to a buildup of ammonia in the bloodstream. By lowering protein intake, the intake of ammonia-producing substrates is reduced, thereby helping to manage elevated ammonia levels effectively.

While increasing fiber intake, incorporating more fruits, or encouraging higher carbohydrate intake can have general health benefits and may support overall nutritional status, they do not directly address the acute management needs related to elevated ammonia levels. In these scenarios, the immediate focus must be on minimizing sources of ammonia production, which underscores the importance of reducing dietary protein.
