You would need...: To get tested by your primary care provider for gluten autoantibodies. After that, a biopsy from the small intestine would need to be done. If the diagnosis were confirmed, you can manage the symptoms of celiac disease by having a gluten free diet, but unfortunately there is no cure.

Stop eating gluten: Celiac disease is caused by an inability to digest gluten. If you can remove gluten from your diet and you get better, that is the best "test" for celiac disease (also called gluten enteropathy).
