Welcome to Healing Well :)
Will this be your first time seeing a GI specialist? The best thing would be to write every little symptom you can no matter how slight it may seem. This can help a lot in your journey for a diagnosis and make it much quicker. From now until Monday, try and keep a list handy at all times to write everything down. As far as the tests that you are suspecting, that seems about
Fiber can be your friend or your enemy but it seems that mostly becomes enemies for some because they introduce it incorrectly. Most often docs will tell us "up your fiber" and send you on your way. Most don't get into the fact that you need to start it slowly and that their are two types of fiber that give very different results. Soluble and insoluble. For people with diarrhea, insoluble seems to be the worst. Do a google search and you will find out what foods and supplements are contained for both of these. Fiber will cause gas and some pain in the beginning but the idea is to slowly introduce it into your diet. Most people that have had bad experiences, tend to shy away and not want to try again. Its important to read up on it, you will find lots of info.
Good luck with your appointment. I hope you continue to post.
