Diarrhea is a classic symptom of celiac disease and may be the only symptom many people experience until damage to the small bowel lining becomes severe enough to spinoff other health issues. There are many with what we call "silent" celiac disease whose symptoms are so minor or occasional like yours that they blow them off. The only way to distinguish between celiac disease and NCGS (Non Celiac Gluten Sensitivity) is to get tested. I strongly recommend that you request your doctor to run these two blood antibody tests: total IGA and tTG-IGA. The antibiotic seems to have put you into some kind of remission at the present time but that may not last.

Not that I can remember but my reaction has never been more than diarrhea and I probably ate a lot of wheat products for years not knowing I was sensitive to it. Dr. never tested me because he attributed it to IBS. 

Hi, I have worked in education in the past. Based on where assigned and building crowding I made adjustments when needed.  I understand completely what you mentioned. I brought food from home in my own Pyrex glass container.  I kept it in my own lunch tote that I kept with me during the day. In the teacher's lounge/staff lunch room I would wipe down the area I sat at with soap and water with disposable paper towel.  I also placed down a fabric placemat prior to unpacking my meal. Unfortunately, one district I could never use the microwaves as they were filled with splatters and crumbs. (To be honest at that one school even if I didn't have this condition, I would not have used those microwaves based on their state of cleanliness). There were mini lockers nearby that I kept my placemat in. I brought my placemat  home weekly to launder.  There were times if the staff had a celebration with cake or pizza I would eat outside or in my car . As the  eating tables also had to display the  party spread. So the pizza and cake was on the communal lunch tables. Those days I just diverted to outside on the grass or my car. When I was fortunate to have a consistent schedule many staff "knew" my spot, and it was usually empty when I arrived. Occasionally, it was taken and it normally was by a substitute who didn't know about me/my situation.  I hope you are able to navigate this new change of building/assignment. I do know these days many districts have crowding and teachers often share classrooms or the same desk. This was often my experience whether in teacher or support staff role. Some districts you don't even have your own desk or space. I hope you do have some space to retreat to when possible. There often times is that awkwardness of a new schedule assignment where they ask why you don't want cake, pizza ,or always bring your lunch etc. For me that happened in every job education or business sector as often times I was the only one with this condition.  I hope this may have offered some support to lessen your anxiety about the new school year  assignment change. Best wishes     

People get genetic modification confused with hybridization. Wheat, as has most of our food crops, has been altered through hybridization to make it more disease resistant, more drought resistant and even to increase the gluten content. Hybridization uses selective breeding/cross pollination to enhance certain characteristics. Genetic modification, on the other hand, uses a "gene gun" to knock out certain genes and replace them with unnatural ones. In some cases, plant genes are replaced with animal genes to achieve certain properties. This is what GMO is about. Have you actually been formerly tested for celiac disease, either by blood antibody testing, biopsy or both, to rule out celiac disease?

Thank you for your response. I have had several different antibiotics over the years and none affected my sensitivity to wheat products which I assumed was due to the gluten in them. However I do believe this time it was an antibiotic I’ve never had before so if your explanation is correct it would seem this antibiotic (cefuroxime 500 MG tablet Commonly known as: CEFTIN, 1 tablet by mouth 2 (Two) Times a Day for 10 days.)  could be a cure for my sort of sensitivity. I assume the hospital IV was the same antibiotic. The IV was ordered because my blood culture showed bacteria in my blood. I remember hearing years ago the gmo wheat was found in some products but I guess that was a misnomer. Believe me after over 20 years of putting up with this sensitivity, despite the fact that growing up eating subs, pizza and spaghetti regularly never affected me, I am so relieved to no longer have to avoid wheat.. I hope!
