What should I know?

The fact you are considering or getting a liver transplant is much better than getting a lung transplant with less complications and a better prognosis. Ask what medications you will be required to take for the rest of your life and their side effects. Will you be a diabetic (Type 2)? Ask for an outlook on the likelihood of it occurring again.
After you get it try and stay positive and avoid slipping into depression, I did (lung transplant) and it has consumed my thoughts rather than enjoying my second chance.

@lynjoy2, Welcome to Mayo Connect. I remember being referred to a specialist when I was beginning my liver journey. And I remember how impressed I was with the amount of knowledge he had about the liver! I also entered the appointment with a list of questions for him, and want to suggest that you begin to write down every question that pops into your head, or anything that concerns you. Don't worry about the length - you can edit it on the 26th.
As a patient, you don't have to know anything - just be prepared to listen and learn. Take someone with you, if possible, as an extra set of ears. You will likely be nervous and that makes it hare to really concentrate or remember. The doctor might want labs drawn in advance of the visit, or want updates to your medical history and medications. But he will let you know in advance.

I received a liver and kidney transplant 16 years ago due to a progressive liver disease. The most important thing that I learned is that any question that I had was always a good one to ask my doctor. So to begin this conversation with you, let me ask you a question to help get your list started: What is your biggest fear or concern related to your liver right now?

Rosemary,
I guess my biggest fear is having to have a transplant and all that entails.
Also, will this affect my work, I am a teacher.

I am already a type 2 diabetic. Does that affect anything? I’m trying really hard to stay positive at least until I see the Dr. I feel sad you are so depressed. I suffer from depression too. Thankfully I have a great psychiatrist who has me on medication that helps.
Take care and I wish you the best.

I am not sure if it will affect your diabetes, are you already taking Prednisolone as that is the cause of my diabetes.
I appreciate your sincerity regarding my depression, I have tried every anti-depressant in the book and suffer most of the negative side effects. I have recently commenced medicinal cannabis however, it is being done carefully due to the fact anti-rejection medication clashes with it. It has proven to be beneficial but is a hard sell with the transplant doctors.
