<s>[INST] Hi, I have elevated liver enzymes and I want to know how serious it is.  My GGT is 110, my AST is 206 and my ALT is 313.  My bilirubin levels are normal.  I was tested for Hepatitis, but they all look negative.  Also, i rarely drink alcohol, I dont eat much red meat, and I am in a normal weight range.  I am 32 years old.  I have been living in abroad and just moved back to Canada.  Can stress affect these levels? or moving from very different climates?  I have also been getting hives, but i am not sure if this is just stress related or has something to do with this as well. [/INST] Hi there, Id cut out alcohol and Tylenol, and all non-essential prescription medications. I'd also try to cut out fatty foods and see if this helps. Sometimes living abroad can cause this, but unlikely with a negative hepatitis panel.  I'd also get checked for autoimmune hepatitis, as this could also be causing the elevation of your numbers.  I hope I have answered your questions. Please feel free to contact me should you have any further questions. </s>
