The pungent, musty breath characteristic of advanced liver disease is called?

• A. Metallic Hepatico
• B. Asterixis
• C. Fetor Hepaticus
• D. Hepaticoacidosis

Answer: (C)

Fetor hepaticus is the distinctive pungent, musty breath seen in advanced liver disease. It happens because the failing liver can’t detoxify gut-derived toxins, so volatile sulfur compounds (like dimethyl sulfide) accumulate in the blood and are exhaled in the breath. This odor often accompanies hepatic encephalopathy and other signs of severe liver failure, such as confusion or lethargy.

The other terms don’t describe this breath change. A metallic breath isn’t the characteristic finding here, asterixis is a flapping tremor seen with hepatic encephalopathy rather than a breath smell, and hepatoacidosis/hepaticoacidosis aren’t standard terms for this breath phenomenon.
