Discussion: Although I do not have chronic liver disease, I am not focused and have difficulty driving; I have chronic fatigue.

As you know, the liver is part of the digestive system. It is very important for patients with chronic digestive diseases. Most chronic patients have blockages in the bile ducts.

Hepatic encephalopathy is when a high level of ammonia in the blood (a breakdown product of any protein) penetrates through the brain's barriers and causes side effects that affect alertness and cognitive ability. Ammonia is a potent toxin that the liver should eliminate after synthesis and excrete through the kidneys. High ammonia levels in the blood and hepatic encephalopathy may indicate liver failure and require a comprehensive liver function examination.
