Serenity, the bloating and discoloration you mentioned are due to fluid retention. The liver is not handling fluids the way it should. At one point, my calves were "weeping" fluid, they were so swollen. Your husband needs to be on a diuretic to help control the edema and ascites. If the ascites (belly fluid) becomes too great, it can interfere with breathing.
If he becomes extremely confused, agitated, or has bad, frequent mood swings, it is an indication that his amonia level is too high and he needs Lactulose to rid his system of the excess amonia.
The liver is the body's main filter. Everything is filtered through it and it filters out toxins (ideally.) In a diseased liver, the filtering function is impaired so a lot of toxins build up in the bloodstream.
If he keeps drinking and continues to refuse medical help, his condition will worsen and you will know it. The swollen feet, in particular, are very painful. I had to get my helper (or anyone who could do it) to press the fluid upwards, a little at a time. (That was before I was placed on diuretics. I don't know why they waited so long...perhaps waiting to see if the cancer surgery would improve the edema, which it did a little, but I still need at least 20 mg of Lasix a day and 100 of aldactone.)
