<s>[INST] My MCV levels are high and my liver enzymes are out of whack.  My hemoglobin is 15.5 and my b12 and folate as well as all other vitamin levels are fine.  I had gastric bypass 8 months ago and have a history of IBS.. I also bruise really esy any ideas.  I am a non drinker. [/INST] Hi and welcome to Chat Doctor. Thank you for your query. These are pathological findings and easily bruises may also be sign of liver damage. High liver enzymes are sign of acute or chronic liver damage and the exact cause should be evaluated. The next step is to look for certain liver damage and most common cause is fatty liver disease. It should be confirmed by ultrasound. Other causes are viral hepatitis, cirrhosis, medications, alcohol intake or autoimmune diseases. To verify exact cause, US, bilirubin levels and tumor markers should be additional done. Then appropriate treatment can be started. I hope I have answered you query. Kindly regards. Wish you a good health. </s>
