Which dietary approach is appropriate for long-term management of hepatic encephalopathy?

• A. Severely restrict protein
• B. Moderate protein intake
• C. No restriction of protein
• D. High protein diet

Answer: (C)

Long-term management of hepatic encephalopathy hinges on preserving nutrition while keeping ammonia under control. Protein itself isn’t the enemy; the body’s ability to detoxify ammonia improves when you maintain adequate protein intake. Restricting protein chronically can lead to malnutrition and loss of muscle mass, which actually reduces the body’s capacity to convert ammonia into a form that’s easier to eliminate. Therefore, the goal is to keep protein intake at normal levels (with overall adequate calories) and tailor the type of protein to the patient’s tolerance, rather than restricting protein. This is used in conjunction with treatments that lower ammonia, like lactulose and rifaximin, and by managing triggers such as constipation or infections.
