Very good advice being offered. I would stay away from oats though, as a rule, they can't be trusted and, many people can't tolerate them any ways.
As for being tested for allergies, what you are speaking of are intolerance's and they do not show up as allergies..completely different analogy. We can be intolerant of dairy and it will not show up as an allergy.
I have been gluten free since July of 2000. I had been sick for years, most of my adult life, in 2000 I was 45 and had suffered for years. My 2nd pregnancy probably triggered my reactions, if not my first...those sons are now nearly 37 and 34. I had tummyaches my entire life though, so I would imagine gluten has messed with me forever, just turned for the worst when pregnant. My symptoms were aches and pains, diarrhea (nearly every day), panic attacks, anxiety...I was diagnosed with viruses, IBS, nervous stomach, colitus, panic attacks, anticipatory anxiety, borderline agoraphobia (which we all know was because I was afraid I would get sick away from home). Before going gluten free I was diagnosed with carpal tunnel, which was the beginning of my neuropathy caused by B12 deficiency because the gluten issues were preventing me from absorbing vitamins and minerals.
Back in 2000, I had no medical insurance, newly divorced, no job...no money to be tested. My sister had been diagnosed in March of the same year with celiac and encouraged me to try the diet to see how I felt. I never went back to gluten, not once. Our dad was diagnosed in 2004 with celiac after years of issues. I do not have a formal diagnosis of celiac, I actually was told 3 yrs ago that I can't be celiac because I have double DQ1 genes, almost identical genes, both gluten intolerance genes and one being known for neuropathy gene also. Double DQ1 genes can make you much sicker than being celiac...many with double DQ1 genes have many more intolerance's than being celiac...such as, I can't eat any grains. All grains contain some form of gluten and not all gluten is the same. The gluten celiac's can't have is in wheat, rye, barley, and sometimes oats...yet corn has it's own gluten, as do all grains. I think glaidin is more of an issue for celiac's. It's true, there is a lot more out there to read about with celiac, not so much info as of yet for gluten intolerance/sensitivity. Often times you will read that being intolerant or sensitive isn't as bad, but believe me, it is! My sister and father do not have any where near the problems I do..I often say I wish I was JUST celiac, it would be much easier.
As I said, I went gluten free in 2000, by 2003 the other intolerance's started popping up, first soy, then corn, then red meats, nightshades, shellfish, dairy...finally giving up all grains. By this time I was suffering from leaky gut and didn't realize it. As I mentioned, I have been on a candida diet since March of last year, finally doing better until this latest setback with the new meds. I saw my rheumy on Mar 14th, started Flexeril and aspirin on the 15th, the Meloxicam on the 19th. By Thurs the 24th I was so sick I stopped all meds and will not try them again. I am still having trouble getting my tummy back to it's normal. Setbacks like this are so hard on my body. I am down 5# from my normal weight now..my doctors not wanting me to lose anymore than I had already lost.
So, being celiac isn't the only reason to be gluten free. Another good book to read is written by Dr. Stephen Wangan..Healthier Without Wheat. All of the Dummie books are great, in my opinion.
Oh, and my diagnosis of fibro was just this last month, although I know I have dealt with it for years. I also have Small Fiber Sensory Polyneuropathy, Sleep Apnea, CFS, Raynauds, and dealt with Fatty Liver Disease after my weight loss this last fall.
