i am currently exploring why with my doctors. i have had this for years and finally got to where eating was such an issue i lost way too much weight. at the moment i am off all gluten in case it is celiac disease. so far i feel alot better and actually think of food, something i have not done in at least 5 years. also i do not feel sick after i eat.
i do strongly suggest you see your doctor about this and don't blame it on fibro till everything else is ruled out. i know i am glad i finally said something. took me long enough!! giggle.
It could be many things...just not Fibro. I would go to the doctor and ask for blood tests for H pylori, celiac disease, liver funtions tests, and anything else he can suggest. It could be delayed dumping syndrome or gallbladder disease or an ulcer. I would go to a Gastroenterologist for guidence on that issue. there are so many ducts that sometimes don't work right that they would have to do a endoscope to take a look. good luck.
