You may also want to consider your family background and health history in considering if you are at risk for being celiac. It is genetic, so you may have other people in your family with Gastro health issues. Also, other autoimmune diseases put you further at risk for developing the disease. Italian and Irish have high rates of celiac in their population and apparently North Africa (http://www.ncbi.nlm....les/PMC3264942/). If you have indicators either by heritage or family/personal medical history, you may want to consider getting tested to document it for your family.
I'm not sure where you are writing from, but your English is quite good! Yeah you!!
I hope you continue to improve off the gluten. It actually took me a few weeks to notice anything different, so the fact that you saw immediate results is a good thing.
