What infection causes hepatic encephalopathy?
The most common infections in cirrhotic patients are spontaneous bacterial peritonitis and urinary tract infections, followed by pneumonia, skin and soft tissue infections. Intestinal bacterial overgrowth is also responsible for hyperammonemia, which leads to hepatic encephalopathy.
How does ammonia cause encephalopathy?
Toxins, such as ammonia, accumulate in the blood. Toxins in the bloodstream can travel to the brain and temporarily (or sometimes permanently) affect brain function. People with chronic liver disease are at risk for hepatic encephalopathy.

Why does diuretics cause hepatic encephalopathy?
Diuretic therapy:Decreased serum potassium levels and alkalosis may facilitate the conversion of ammonium (NH4) to ammonia (+NH3). Diuretic-induced hypovolemia is one of the most common reasons for patients with previously well-controlled HE to present to the emergency room with worsening mental function.
Which of the following symptoms is associated with hepatic encephalopathy?
