Welcome! I am impressed you found this so fast. Took me years to find this resource and I am so thankful. First off, as a mother I am feeling for you to watch this and deal with it. You may want to find her a place she can ask questions and vent her frustrations. (not sure if there is an age limit here) Its great to be able to ask even the most basic questions. My holistic/nutritional doctors are convinced that Crohns is related if not caused by food allgeries. a very large percentage of Crohns patients have food allergies. most insurance wont cover the blood test, but many offices will over a reduced cash copay. Its very helpful, that way you are for sure staying away from foods that are a problem. My experience has been that wheat and dairy naturally cause problems is just about everyone, they just dont really know it. I just started this diet 3 months ago, along with supplements, and my labs are the best they have ever been. They also are doing a "leaky gut" test on me this week. This is a drink that tests the permiability of the intestine. Many with GI issues dont absorb what they should and do absorb some things they shouldnt. They also told me to stick with foods that are closest to their original form (not processed). In terms of fruits and veggies, they are always easier during a flare up if they are cooked, canned, soft, etc. Since she already has the arthristis diagnosed (which happens with many people eventually bc its an autoimmune disease as well) I would ask the nutritionist about adding glucosamine. It will help both problems. They have it in powders, Monavie products have it, and many others.
The hardest part of this disease is that it is one that is MANAGED, not cured. Sometimes you can do everything right and it will still persist out of no where. That will be frustrating for both your daughter and your family. Also, your dr will be critical to your progress. If you are not ecstatic about your GI, keep interviewing them until you find one. I have gone through several to find one that will honor my desire to be preventive and use natural methods, as well as realize there is still a need for RX sometimes.
You will always find lots of support here! And you can search for your topics first to see if anyone has already asked your questions (which likley they will have!!!)
Good luck! Keep up posted.
