My son, who is 8 years old, has been getting sick about once a week for the past month and a half. No fever, I notices a blue tint under his eyes and his skin would get clammy. Once he got sick he would lay down and then be fine. I took him to the doctor and she started with possibly alergies, seeing it was the beginning of alergy season. When I went in for the follow-up my husband had been diagnosed with Celiacs, so she said lets get the kids tested. My husband was tested because his sister was diagnosed, not becaue of any symptoms, where his sister would really feel sick after eating gluten.
Anyway, my daughter's tests came back negative-but we will have them tested again in a few years-as recommended. My son's came back maybe, then we had the promethus test done, which also came back negative. We have decided to have our son be gluten-free for a month and see what happens. With all the other things that could cause a child to get sick like this Celiacs would be a relief!
If your niece is getting sick a lot, suggest to your sister-in-law to cut-out foods for a month or so to see if there is any allergy-including gluten. This may be simple enough. If she does-great-if she doesn't-then know that you have done what you can to help your niece and move on. Unfortunately her fate is altimately in your sister-in-law's and your brother's hands, they need to decide what to do. Another unforunate thing is that in this country Celiacs is not recognized, it is still seen as rare in many circles so getting a doctor to test a child could be difficult. We are just lucky that our doctor is open-minded and suggested getting the kids tested-I didn't have to. She is a new doctor, I know our former doctor would not have them tested-and he is fairly young so you would think fairly open-minded.
I have gone on long enough, but I do agree, know in your heart that you have tried to help your niece, maybe when she is older and making decisions on her own you can help her with gluten-free to see what happens.
