I had the same isues and was given at least 10 different diagnosis. Finally I found a doctor who explained that about 5% of Gall Bladder surgeries result in whats called dumping syndrome. Your bile instead of being stored in your gall bladder drains directly into your stomach and causes all kinds of problems. He prescribed Welchol which is normally for high cholesterol. All it does is sit in your stomach and bind to bile and kind of regulating the system. Since taking this medication I have had no problems at all.
