I don't know a lot about it, but my mother was diagnosed with celiac disease, and after many years of crazy symptoms and feeling horrible all the time, she started a gluten-free diet. In addition to the bad symptoms going away, she reports that she has much more energy.<br><br>
So definitely try out the dietary changes! It might make a huge difference.<br><br>
Edited to add: Since she likes to cook, I bought her some gluten-free cookbooks, but there are a lot of foods available in a gluten-free form.<br><br>
She has to be VERY careful, since just a bit of gluten in the starch used to thicken a restaurant sauce can give her problems. The more natural her foods, the better.
