@shacquie, if your mom's doctor recommends a liver transplant, you may be referred to a transplant center. You're also free to select a transplant program on your own or choose a program from your insurance company's list of preferred transplant centers.

I moved both your discussions into one so that people can see more of you and your mom's story. I see that you are very worried about your mom. It must be hard to see her suffer and even harder to wait for an appointment to see the GI specialist. Thank goodness she was given lactulose by the ER doctor. It will lower the level of ammonia by increasing bowel movements. It also may improve the health of her gut, making recovery easier.

As @katebw suggests you might wish to stay close to your mom the next days until her appointment with the GI. As Kate and @gently said, don't hesitate to call the GI office to see if you can get an earlier appointment.

If you would like to seek the opinion of Mayo Clinic experts, I recommend calling them or using the online form to request an appointment. You can find the Arizona number or online form here: https://mayocl.in/1mtmR63

Does your mom live with you or near you?
