Yes, you can have gluten issues and no GI symptoms. Read up on silent celiac. There may be more silent celiacs than regular GI symptom celiacs. People walking around every day without GI symptoms but with other things happening in their bodies. They estimate over 90% of people with celiac disease are undiagnosed.
I understand that this is a really hard question, but just from what you guys know, do you think there is a possibility that all this could be caused by gluten??? It just seems crazy to think so! Fortunately if it is, I have a great way to test and check for improvement... my hormones!
