My liver results came back slightly elevated at the same time I was diagnosed with a underactive thyroid (hypothyroidism). You may want to google hypothyroid and check to see if you have any of the symptoms/ If so, ask your doctor to run a thyroid panel to see if your TSH levels are elevated.
It's not much help, but that's why my liver results were elevated. I'm not sure what else might cause that. Good luck to you.
Having liver test results that are "elevated" doesn't mean your liver is "enlarged." It means the blood work came in with higher counts for liver function than usual. Did the doctor also tell you your liver was itself larger than normal?
A blood test would not necessarily indicate an enlarged liver, but a CT scan, ultra sound or MRI would. Blood work would indicate enzyme levels, cholesterol, etc. The results of your blood work should also be accompanied by what levels are normal, on the high and low end.
