I agree with the second opinions, especially at major academic medical centers. There are a variety of reasons for persistent abdominal pain
, including celiac disease, upper
digestive disorders, liver/gallbladder disease, inflammatory bowel disease or malabsorption, among others.
Imaging the abdomen, including a CT scan and/or MRI, as well as both upper and lower endoscopies should be done. Blood and stool tests excluding celiac disease and malabsorption can also be considered.
