When would a temporary protein restriction be indicated in hepatic encephalopathy?

• A. 0.8-1.0 g/kg/day
• B. 0.6-0.8 g/kg/day
• C. 1.5-2.0 g/kg/day
• D. 2.0-2.5 g/kg/day

Answer: (B)

In hepatic encephalopathy, lowering the gut’s ammonia production helps improve brain function, since ammonia from dietary protein is a major contributor to the neurotoxic load when the liver can’t detoxify efficiently. A temporary protein restriction of about 0.6–0.8 g/kg/day reduces substrate for ammonia production while still meeting essential protein needs. This level is used during acute HE to help reverse or lessen symptoms, and once the patient stabilizes, protein intake can be increased toward 1.0–1.5 g/kg/day with attention to protein quality and overall calories to prevent malnutrition. Higher protein intakes would raise ammonia levels and risk worsening HE, while a milder restriction may not sufficiently reduce ammonia during the acute phase.
