What is the rationale for maintaining higher protein intake in cirrhosis?

• A. Prevents muscle catabolism and promotes gluconeogenesis
• B. Increases ammonia production
• C. Reduces appetite
• D. Improves fat absorption

Answer: (A)

In cirrhosis, preserving lean body mass and ensuring a steady supply of amino acids for metabolic needs is crucial. Higher protein intake helps prevent muscle catabolism, which is important because muscle loss worsens strength, mobility, and overall outcomes. At the same time, amino acids from protein provide substrates for gluconeogenesis, helping maintain blood glucose during fasting and supporting energy balance in a body where liver function is compromised. This combination—protecting muscle while supplying substrates for glucose production—is why higher protein intake is recommended.

The other ideas don’t align with the main goal. Increasing ammonia production would worsen hepatic encephalopathy, not help management. Appetite changes aren’t the primary reason to maintain higher protein, and fat absorption isn’t directly improved by protein intake.
