Thanks for your comments! Mom currently doesn't have any real symptoms except she does tire easily...but she's been like that for a long time. She also has severe osteoporosis. She had a couple of weeks just after Easter when she wasn't feeling well -- no appetite, no energy, dark urine, just feeling generally lousy, etc. -- but she seems better now. She doesn't have another doctor's appointment until mid-August, and then she is scheduled to have a gastroscopy (sorry if that's not spelled right) to check for varices in early September. Thanks again for your responses!
