Hi Jennifer l just saw your post but elevated ammonia levels are not always from alcohol. I have elevated ammonia levels and mines is from non-alcoholic liver disease. Mines was from medications. Ones l was allergic to and also recall one and antidepressant. I was placed on 3 recall high blood pressure meds. And when l came to the mayo clinic on my records the doctors always put on that l was previously on depakote. Which l told the doctor l was having reactions too. So it was the medication. But they really don't look at your ammonia levels. They go buy your symptoms. So now l just have to end differently and rest. So it's not always from cirrhosis.
