Yes th doctor said it was very enlarged but they never say to much! I guess it is just a part of PBC. But thanks for all you healp on this matter!
Have you asked your doc whether your liver has expanded, or are you making the assumption based on what you saw on a scan? The liver is quite big normally and extends quite aways over toward the left-hand side of the body. So you need to find out whether there is actual enlargement in that area or not.
If any organ that lies under the diaphragm enlarges and takes up more space in the abdominal cavity, that pressure has to go somwhere and it usually presses upward toward the diaphragm. This can cause a person to feel like they can't take a deep breath. But again, you need to ask your doc the cause of your feeling short of breath.
