Hi There..my Husband Has Very High Liver Enzymes. Medicines Have

Hi there..my husband has very high liver enzymes. Medicines have been stopped, further tests done. Still high. Liver function normal. Symptoms are fatigue, bleeding (bright red) from anus, diareaha , weight loss, abdominal cramping...everything leads to ulcerative colitis. I have been online researching. He is in a lot of pain. Not jaundice. Any ideas? All other blood work has come back normal including celiac
