Hi, all. My mom has non-alcoholic liver cirrhosis. She has been hospitalized three times for ammonia build-up and has been taking the meds (an oral pill and Lactulose) for a few months. Only a few good days in those months. Doctor says nothing more to be done now about ammonia because of other problems, heart valve replacement that can't be replaced, insulin diabetes. We are starting hospice tomorrow. All meds discontinued, except pain meds and anti-anxiety meds. Does anyone have a crystal ball to say how long she will have before she gets to coma stage after ammonia builds up? Thanks in advance so much.
