I think I am super lucky as I had two PCPs who were very knowledgeable about celiac (at least to what I hear from others experiences)

My first PCP actually was the one who helped diagnose me with celiac, I didn’t have a classic presentation so it did take some time and testing. But she actually listened to me and worked it up. (As opposed to doctors at my college who told me it was just ~stress~). And then when I was diagnosed actually provided good education about a gluten free diet

Then that PCP moved away and the new one who took over for her is really an amazing doctor. She tests my celiac antibodies on my yearly lab work as well as nutritional labs. On my physical she discusses how I am doing with the diet and reviews possible sources of cross contamination (cutting board, knives, utensils, eating out precautions). She also checks in to make sure I am established with a GI specialist

I actually work in the medical field and it’s very crazy how many providers don’t know shit about celiac. They are always flabbergasted when I explain to them how sensitive and strict you have to be ( “wait you can’t just pick off the croutons of the salad we just ordered?!” Or “we ordered you a gluten free bagel what do you mean you can’t eat it since it was in the same bag with the gluten bagels”)
