I had laparoscopic surgery to treat what was thought to be endometriosis, but none was found. My doctor did find that my liver was discolored though. From the image she showed me (while coming out of anesthesia), I believe it all looked like a greyish color. Do you know what that might be caused from? I'm not a heavy drinker. Maybe once a month, if that, I may have a few drinks. I've been to a gastro who did blood work and tests for ibd, colitis, gluten and lactose intolerance. I only have ibs.
