Allie, if you can get a Health Care Surrogacy or Power of Attorney, you can request her medical records. I learn more from my medical records than I do from anything that is ever told to me. When I don't see my questions answered in the medical reports, then I ask. For example, I had to ask what genotype my hep C is, as nobody ever told me nor was it mentioned in the records (it's 1a.)
There is a foul or sweetish odor on the breath of end-stage patients, known as fetor hepaticus. There is also encephalapothy, muscle wasting, inability to manufacture platelets, and various other symptoms of end-stage patients. Some of these may improve when your mom is in the hospital and having the symptoms managed (such as with monitored Lactulose.) This doesn't mean that the disease isn't progressing, just that the symptoms are better managed.
Have they gotten the infection under control?
Allie, your mum is in major denial. She doesn't want to acknowledge that the drinking has caused this and she really doesn't want to stop. If your finding out just how bad off she is is for your own information, fine. But also know that there really isn't a thing you can do. Just reread the long post you just wrote and I think you can see how bad things are without having to read any medical records. Because she is not willing to admit the alcohol problem or ask for help, all the docs can do is treat the symptoms.
I believe that you would need to get her signature to get Power of Attorney and she would also have to sign legal paperwork to assign you Medical Surrogacy. If you want to see about having her labeled mentally incapable of making decisions or caring for herself, you need to consult with a lawyer. Over here, they don't charge for a consult. I know the laws are different overseas, which is why I suggest meeting with an attorney. Also, I wouldn't want to give you wrong information, even over here.
If she is released home, you could try to get home health care for her. Then there would at least be someone checking up on her regularly.
Rick, you've come a long way in 1 1/2 years, by the grace of God and your own willingness and humility.
Allie, this is a safe place to vent and we all need to do that from time to time. In reading back what you wrote, it is easy to see how much denial your mum is in and how much the whole situation has taken over your life. One thing I learned in AA is that I can't control other people. I can only control my reaction to them. I also went to Codepency meetings and learned how to detach with love, and not get sucked into a toxic relationship. It's necessary to learn these things in order to take care of one's self. If you believe in prayer, try praying for the things you wish for her, such as sobriety and better health. It may not help her, but it will do wonders for YOU.
I'm glad to hear that she will be in hospital 2 more weeks. The longer she is without alcohol, the better her chances of staying away from it when she gets out. But she also has to have the desire and willingness to stay sober, and I'm not sure she has those. A miracle is, indeed, needed.
