Small intestinal bacterial overgrowth and Celiac disease - coincidence or causation?

Abstract

Celiac disease (CD) is an autoimmune enteropathy which is becoming increasingly more common in the developed world, with around 1% of the general population now thought to be affected. A complex condition, CD results from an interplay of genetic and environmental factors and the exact mechanisms of the condition are not well understood [1,2]. Furthermore, CD is associated with other malabsorptive pathologies, one of them being Small Intestinal Bacterial Overgrowth (SIBO) and this association is the focus of this article.
