What complication may arise from untreated hepatic encephalopathy?

Untreated hepatic encephalopathy can lead to coma as a significant complication. Hepatic encephalopathy occurs due to liver dysfunction which causes an accumulation of toxins in the bloodstream, particularly ammonia. As these toxins affect brain function, symptoms range from mild confusion and lethargy to more severe manifestations like stupor and coma.

If hepatic encephalopathy is not addressed, the progression of the condition may lead to a state where the patient can no longer maintain consciousness or purposeful interaction with the environment, hence resulting in a coma. This severe outcome underscores the importance of monitoring and treating hepatic encephalopathy to prevent deterioration of the patient's neurological status.
