Which precipitating factor should be addressed in the management of hepatic encephalopathy?

• A. GI bleeding
• B. Hypernatremia
• C. Hypertension
• D. Hypothyroidism

Answer: (A)

GI bleeding commonly worsens hepatic encephalopathy because blood in the gut provides an abundant source of protein that gut bacteria break down into ammonia and other nitrogenous wastes. In liver failure, the damaged liver can’t detoxify this ammonia effectively, so it enters the bloodstream and reaches the brain, triggering or worsening encephalopathy. Addressing this precipitant is a priority in management to reduce ammonia production and prevent progression, often alongside therapies to lower ammonia levels like lactulose and rifaximin. The other options aren’t typical triggers: hypernatremia is not a classic precipitating factor (hyponatremia is more commonly associated with HE), hypertension isn’t a known precipitating factor, and hypothyroidism doesn’t acutely precipitate hepatic encephalopathy.
