Well, at least YOU want to be more informed, and bravo to you for wanting to be proactive for her! Some people just do not want all that information. It is not wrong. Just a different way of coping with things. Still, she can become a member and not post, if that's what she would prefer. Or, just search and read to see if something fits her scenario. Again, no right or wrong on that.
Abdominal pain can be tricky. Been there. But, not to her extent. One suggestion, if she has not done this, is to keep a diary noting what she eats and does, along with recording each pain episode. Imaging does not always nail down a cause of pain, particularly if it is due to IBS or adhesions. In thoses cases, it is a detailed history that leads to the diagnosis.
Good luck, and tell her she is welcome to lurk or join, whatever suits her!
