I carefully avoid gluten, especially read ingredients at the store. During a colonoscopy a few months ago, a sample of my small intestines was biopsied and the damage to the villi was obvious. My GI guy also found I was positive for heliobacter so I went on an antibiotic regimen until that cleared. He also had me take celiac panel (I am positive).

My brother, also a celiac, had anemia and, following a strict gluten-free diet, he is no longer anemic.
