question: My Father has advanced Cirrhosis and from the description of symptoms he also has HE. He is a big guy - 200lbs 6 and he is shouting and confused, hallucinating vividly, trying to get up from bed, angry, his hands, legs and feet shake. He has moments of lucidity. After eating just a few bites of food for 8 days he gorged on food yesterday and couldn t get enough. He has constant mood swings. He is going into a Hospice facility today, but we are worried he will be too much for the staff to handle the way he is. Is there any guideline for how long someone can experience these severe symptoms of HE before ammonia levels increase and he goes into a coma?
