Your symptoms would not be typical celiac disease symptoms, but still could be related due to possible nutrient deficiencies.  The most common nutrient deficiencies associated with celiac disease that may lead to testing for the condition include iron, vitamin D, folate (vitamin B9), vitamin B12, calcium, zinc, and magnesium.  Unfortunately many doctors, including my own doctor at the time, don't do extensive follow up testing for a broad range of nutrient deficiencies, nor recommend that those just diagnosed with celiac disease take a broad spectrum vitamin/mineral supplement, which would greatly benefit most, if not all, newly diagnosed celiacs.      

This is a difficult situation, and one that your employer may not take seriously. It's possible that they don't have a way to accommodate your issues, but I don't know much about your work environment. Obviously moving you to another work area would be ideal, but would or could they do that? If not, you might be stuck having to wear a K95-type mask at work to avoid breathing any particles, but they still could end up on your skin. Another alternative is searching for a new job.

This is an interesting theory, but it’s important to note that Ozempic, while it does slow digestion, doesn’t change the body’s immune response to gluten in individuals with celiac disease. Even if symptoms seem reduced, the immune system is still triggered, which can cause the same long-term damage to the intestines, regardless of symptom severity. Regarding sourdough bread, while it may have lower levels of gluten depending on how it’s made, it’s still not safe for people with celiac disease unless it’s explicitly gluten-free. The immune response to gluten in celiac disease is triggered by even tiny amounts of gluten, so adhering strictly to a gluten-free diet is essential for health and healing. If you suspect Ozempic or other factors are influencing your symptoms, it might be worth discussing with your healthcare provider or a specialist to ensure you’re fully addressing your health needs.
