Elevated liver enzymes not eating

Hi. Looking for some advice. My large 6 yo neutered male cat slightly overweight (was 7.3 now 6.8) stopped eating over a week ago, I tried many different foods to get him to eat but when he completely refused anything I took him to the vet. They did blood work and said he had elevated liver enzymes, he was also constipated. They put him on an IV line and gave him antibiotics, pain relief and fluids. This continued for 4 days where they then said he seems good and can go home. I have had him home for 3 days and to me he is still not eating enough. I am having to coax him into eating by placing him in front of the bowl, moving the bowl around to him when he walks away, hand feeding him and I just don't think this is how he should be. He is only eating about 1-1.5 of those small wet packets (85g ea). He is still on antibiotics for two more days. Is this normal is he still just recovering and I should keep just feeding him like I am? Thanks.

This is my boy Dillo.

He is a cutie.  It sounds like your kitty has or is going into what is called fatty liver or hepatic lipidosis.  He probably stopped eating because of the constipation, not eating enough is what causes fatty liver.  The cat's liver isn't very efficient at metabolizing fat.  When they aren't eating enough the body starts using it's fat stores.  If too much fat is broken down at one time the liver can't keep  up  and fat deposits begin forming on the liver.  Fatty liver then causes a cat to loose his appetite and become nauseated at times so it is a vicious  cycle.

The only  'cure' for fatty  liver is getting enough calories so the body quits trying to use it's fat stores.  You may have to syringe feed.  The  main thing is to use the side of the  mouth and go slow, give a little let kitty swallow and then give a little more.  There is a prescription food from Hill's called A/D that is good because it is high calorie.  The Royal Canin version is called Recovery.  You can also  get a supplement called Denamarin which can help the liver heal.  It has the active extract from milk thistle and SamE in it.

Thanks Denice, I am trying to feed him at least 4 times a day and are getting about 160g into him total. I hope this is enough to counteract the fatty liver thing.
