Why does hepatic encephalopathy develop in liver failure, even when intravenous glucose is administered?

💡 Explanation

Hepatic encephalopathy arises due to impaired urea cycle function in the damaged liver, leading to ammonia accumulation. Because the urea cycle cannot efficiently convert ammonia to urea, ammonia levels rise and cross the blood-brain barrier; therefore, intravenous glucose cannot compensate for the detoxification failure, rather than addressing the underlying issue.
