So sorry to hear that you and your parents are dealing with this. Why did they say your mom wasn't a candidate for transplant? Is she seeing a hepatologist? GI docs are good but hepatologists are more specialized in diseases of the liver.
We have a lot of caregivers on this forum so I'm sure you'll have responses from them soon. Please feel free to vent anytime...everyone is here to listen.
Jrzegirl, welcome to the forum. I'm not very impressed with her doctors, from what you've stated. I definitely thinks she needs to be seen by a hepatologist. You need some solid answers. Do you think that the companion you got for your mom is able to take care of her medically? Give her meds, turn her frequently, etc.? Did you look into home health nurses? I also would insist on a Hospice referral.
Your mom sounds like a very sick lady. She needs to get the proper medical care.
