Hi, Honeybee, and welcome to the forum. As you can see, this site is full of knowledgeable and caring people.
First of all, it's great that he stopped drinking 3 years ago, so he doesn't have to worry about that. Being a transplant candidate requires 6 mos. of sobriety. If the patient is still drinking, that sobriety has to be documented, which makes for a longer wait. However, the fact that he continued drinking for 10 years following diagnosis of cirrhosis, means that he caused the cirrhosis to worsen. It could have been stopped in its tracks or slowed down had he quit drinking immediately after diagnosis.
Stage 4 cirrhosis is considered End Stage Liver Disease (ESLD.) As ML and A. Ziffle said, he needs to get medical care as quickly as possible. The swollen belly is ascites (fluid in the belly cavity, for which he needs diuretics and a low-sodium diet.) Yellow eyes is jaundice (from elevated bilirubin level.) Blood in stool means that he is bleeding internally, possibly from varices (swollen veins that leak or burst) or it could be hemorrhoids.) If he has varices, they can be banded. I agree that the best route might be through the ER. They will likely do a direct admit. Is there a teaching hospital in your area? If he can go there, they likely have a program for those with no insurance where he can be seen free or at very low cost. With a wife and 6 kids, there is likely not much money left over at the end of a pay period. In addition, I doubt he will be able to continue working in his present condition.
Once he gets seen and has blood work and scans, get copies of the records and apply for SSI or SSD for him (they will evaluate for both) and they will assess him for Medicaid at that time. As ML mentioned, it takes 2 years from time of application to get early Medicare, so it's best to start the process as soon as possible. But do wait until he is seen and has some current medical data.
It is possible for him to come back from the brink, but he definitely needs medical intervention, certain meds, etc. Do NOT wait on this. Time is running out. Meanwhile, he needs to eat a healthful diet: NO beef (too hard for a damaged liver to process and makes the patient feel sicker); lots of fresh or frozen fruits and veggies (if you must use canned, rinse the beans or veggies to eliminate a good deal of the salt.) Become a label read and choose low-sodium foods. He should drink purified water and low-fat foods. No fried foods.
I suggest you read the info in the folder at the top of the page entitled Hepatitis Resources. It is about liver disease in general and not just viral hepatitis. It breaks down the stages of liver disease and there is lots of other good info in there. Also check out the Caregivers thread. It's a place where you will get support and information from other caregivers and where you can just vent.
I'm glad you found us and hope you will become an active participant in the forum. You will learn so much here. If you have any further questions, feel free to ask and someone should have an answer for you.
Hugs,
Connie
