Mallshopper, welcome to the forum. I know you will get a lot of information and support here. I suggest you start by reading the folder at the top of the page entitled Hepatitis Resources, which has a section on ESLD. Liver disease causes severe, chronic fatigue, so the sleeping is normal. However, if she's sleeping 22 out of 24 hours, it's probably an indication of how sick she is. Is she seen regularly at the transplant center? If so, I suggest you go with her to her next appt. and voice your concerns and ask for ways to help her. It's important that she take her meds and eat a healthful diet with no beef. For transplant, one has to be sick enough to get a new liver but, at the same time, healthy enough to survive the surgery. So it's a hard balancing act.
What is her ESLD from?
Perhaps other caregivers here can give you some input.
Mallshopper, you sent me to the Taber's medical encyclopedia for that one. I found that alpha-1 antitrypsin (note spelling) deficiency is a rare, inherited disorder that is associated with early development of emphysema and also with early development of hepatitis in infants. So I suspect she had developed hepatitis when young and it progressed to end-stage liver disease.
I hope she will feel better after her hospitalization.
