Oh good luck with your challenge and I hope you're able to feel better soon!
Yes, I am well aware of Michael Marsh and his thoughts and they are certainly in the back of my mind.
I was on gluten for 5 months when I had the most recent antibody testing. Admittedly my TTG was the highest I've ever seen it but it's still a 7 and the reference range goes up to 20.
That is true most people on the board do refer for Endoscopy and are responsible in their replies to people who are initially reaching out. But I did have experiences where some folks will tell people that certain tests are only positive with celiac disease. Which is not the case, so I'm just reminding those folks.
Yes!!!! My best advice to expedite healing is to NOT eat out until you are feeling great and really think you have mastered the diet. If you must eat out, use a site like "Find Me Gluten Free" and select only those restaurants reviewed by celiacs. Otherwise pack your own food and eat at supermarkets. I hope you feel better soon!
Why? Why bother to get tested? A gluten challenge can be brutal and long (8 to 12 weeks for the blood test and 2 to 4 weeks for the endoscopy):
I just had anemia which prompted my doctor to run a celiac panel. I waited 7 weeks for my endoscopy due to work constraints. I ate gluten like crazy (I knew I had celiac disease in my heart). At the end of those 7 weeks, I had all the classic gut symptoms which took over a year to resolve. Even a glutening has triggered new (I think) additional autoimmune issues. I would urge you to to carefully consider the benefits of a challenge based on your current AI issues. At least talk to a good doctor.
My hubby has been gluten-free for 16 years -- long before my diagnosis and he does not know if he actually has celiac disease, but we know gluten makes him sick. He chooses to never do a challenge.
As far as healing or seeing results. It varies as we are all different. My anemia, with supplements, resolved within three months but other issues took more than a year and I already had a good handle on the gluten free diet.
Finally, reducing gluten is not an option for a celiac. Anything over 20 parts per million can trigger a celiac disease flare-up for most celiacs.
I hope this helps. Just be sure you really research this throughly is my non-medical advice.
People here are told to go to a gastroenterologist for an endoscopy if they show high on any one test. They are not told they have celiac. Weak high numbers can be other things, but strong high numbers are celiac most of the time. That's what my gastro told me. As nobody here is a doctor we can only give an opinion.
