You certainly could have Celiac Disease or Non-Celiac Gluten Intolerance.
It is VERY important to have your doctor order a full celiac blood panel BEFORE you remove gluten from your diet. The antibodies measured in these tests are produced in reaction to gluten ingestion.
Also a good idea to be tested for nutritional deficincies - celiac can cause malabsorption issues.
Hang in there - make sure all tests are completed and then remove ALL gluten for at least three monts as elimination is the only test for NCGI.
Thank you for the reply Lisa
I'll take your advice and get a doctors appointment asap! I will also continue with my current diet until I've see the doctor.
