Crohn's or what? Need lend a hand asap!?

I'm a 15 year old female and have be sick for the past 1 1/2 years but have had stomach problems for 5 years presently. I have went through every blood, urine, and stool test feasible, endoscopy/colonoscopy, abdominal ct, upper gi, and most recently a sweat chloride test. I'm supposed to be going through a capsule endoscopy soon, and be getting the rest of my experiment results back (few blood and stool).
I tested positive for antibodies for Chron's, back when the inflammation in my stomach and colon be biopsied the results came back inconclusive. Right after the procedure my GI doc started me on prednisone back have now weaned me off because he is not sure if I have Chron's immediately. Is it still possible that I have Crohn's?
I also tested high borderline on my sweat test and on the repeat my even was 59 (60 is positive) and am waiting for my blood test results to see if I have cystic fibrosis.
The doctors are giving up and classifying me as have an eating disorder, but I love food, am not afraid of it, and want to gain weight.
What is wrong with me?

Here are my symptoms ~
* Nausea
* Extremely severe sharp stabbing constant stomach niggle
* Diarrhea
* Night fevers
* Headaches in the morning
* Fatigue
* Indigestion and GERD
* Unintentional weight loss (went from 120lbs to 85lbs at 5'8" contained by about 4 months)
* Back and joint pain within knees and hips

First, I want to say how brave you are to be going through all you are . It is horrible to not feel resourcefully. When I was your age I went through a lot of what you are going through. I am definitely no expert, but, I can tell you what worked for me. I found out, after a lot of trial and error, that I was sensitive to dairy products. Milk, especially, made me sick to my stomach, diarrhea, headache (especially in the mornings), gerd, etc. The diarrhea would contribute to the weight lose. My suggestion to you, cut the dairy products out for a few days. If that's the problem then you will know particularly quickly. Have you been tested for lactose intolerance? That's the bodies inability to digest dairy properly. I hope I've been of some facilitate. Don't get discouraged. Another thought you might suggest to your parents is to try a different doctor. Take all your records beside you and get some new ideas. I hope within some small way I've helped. Good luck & God Bless.
Sounds like you own good insurance, the major side effect of that is a
zillion test.

With these problems you might as well fixate on the study of human physiology and medicine. You will have to study some chemistry to abet it make sense.

You can cheaply get on Amazon.com a used Human Anatomy and Physiology text by Elaine N. Marieb.

There is a free and trusted medical certificate on line called the Merck Manual of Diagnosis and Therapy (see the link below). Keep surrounded by mind its published by a drug company so double check on the medication recommendations.)

You have to be a detective and observant scientist, make a account of what you eat and when.

The top things to look out for which are common problems:

1) Bacterial Food poisoning which you are at higher risk of by drinking out, the more you eat out the more you get it. Typically it takes almost 1 1/2 days of lag time (but staph food poisoning can hit in hours.) It may not be your problem but it can make things worse.

2) An 'allergy' to some flours (see malabsorbtion syndrome). But if its a true allergy afterwards besides diet change chromolyn might help. Antihistiamines?, I don't think they ever tested them to see how it affects food allergies.

3) need of fiber in diet (solved with an orange a afternoon, or if that is too expensive oatmeal. Again, may not be your problem but it can make things worse for most people to enjoy a low fiber diet.

Besides this get a board certified gastoenterologist. The Merck Manual also comes in a home edition, but the one linked above might assistance your family decide on tests.

This adjectives assumes a GI problem, the difficulty of medical practice is diagnosis. Sometimes a tumor that secretes hormones is a problem, and that would also give the same signs.
