You didn’t mention how she was diagnosed, that would help.
I have lived with crohn’s for the past 28 years. When I was diagnosed, I did a lot of digging to learn about it, and to learn about the medications and their side effects. I found that the Crohn’s & Colitis foundation is a great resource. I would suggest you check that out. Your daughter can live a full life, and doesn’t have to hindered greatly by the crohn’s. You don’t know how the crohn’s will effect her in the future, and I assure you that the doctors can’t predict that, either. It may go into remission for long period. Take things one day at a time, be patient and she will learn how to recognize problems. It effects people differently.
My brother and I, were both the same age when we were diagnosed, we’ve both had 3 surgeries (almost identical). However, I also have a sister and a niece who were diagnosed with crohn’s, but their’s are mild, never had surgery. Her daughter was 14 or 15, I believe, when she was diagnosed. She is doing well and seems happy, but she has 2 uncles that have moderate to severe Crohn’s and I suppose she feels very lucky that she hasn’t had to have any surgery.
And as for the Crohn’s Cookbook, well, people have different tolerances. For instance, I can eat jalapeno peppers (in moderation, of course), but some people can’t. Some may be able to tolerate eating an orange or an apple, not me. It is kind trial and error. Generally, raw fruits and vegetables are out. high fiber is out, nuts of any kind, and try to avoid fried foods. Smaller, more frequent meals would alleviate big worries on types of food, too.
