You need to follow up with the doctors so they know it hasn't cleared up on its own. I would suspect food allergies or gallbladder problems or diabetic gastroparesis.
Hi,
I have trouble sometime keeping food down too. But, my issue is neurologically related. She being able to keep done dairy products could be related to ulcers in stomachs. But, the fact that a doctor is unable to help means it could be something else or not. Has your doctor tried nuclear medicine. They can use radioactivity to spot abnormalities in the digestive tract. But, your doc should know best.
