Your doctor should have explained fully what he meant!
I would call back and ask if you have any questions related to your health. Sometimes looking for answers or checking of books/internet can cause alot of stress and worry, I wish you luck and hopefully its nothing to worry about.
Could it be that maybe he meant a 'fatty liver'? What test did they perform on you? Was it an ultrasound?
wow, I have no clue....never heard of that...your dr. didnt explain it to you fully? you should post the answer when you find out what exactly it is, I have no clue but am interested in knowing
