in reply to @hawkssr I too have the same problem, and it is attributed to the dilation of my liver and pancreatic ducts which were discovered incidentally almost 4 years ago. I wish I had your appetite, as I have none, and have to set timers to remind me to eat. I have lost 40 pounds in one year, and while I have gotten used to my "new" look, it disturbs many. Let me know when you find out what is causing your weight loss. I recently had the tests described by @stageivsurvivor and they were all relatively normal. I remain a medical mystery.
