Hi Janice,
I guess if she were my case, I'd be hesitant to change anything just based on the ultrasound findings, especially when they could equally be interpreted as good rather than bad. Are you brave enough to do an ultrasound guided fine needle aspirate, or is the cell layer too thin. In the absence of any concrete symptoms and signs of problems, I'd hold off making changes. Was there a particular symptom left outstanding, besides what you're seeing in the ultrasound? If not, I would be hesitant to make changes, apart from giving Milk Thistle, which has been shown to stimulate hepatocyte regeneration.
Let me know if there is something going on now that specifically concerns you besides the ultrasound.
Steve
