Etiology and pathogenesis of inflammatory bowel disease (IBD) are not clear, but colonic mucosal damage is known to be a critical factor. In recent decades, many studies suggest that interfering with the energy metabolism of epithelial tissue could result in the widening of intestinal epithelial cell gap, increased bacterial translocation across the epithelium, decreased mucus secretion, and intestinal mucosal barrier dysfunction. Bacteria and antigens adhere to the intestinal mucosa, enter into the lamina propria, activate inflammation, and initiate the pathogenesis of IBD. The lack of energy fuel butyrate and mitochondrial dysfunction are the causes of abnormal energy metabolism of the intestinal epithelium. Improving energy metabolism and protection of mitochondrial function can alleviate the seriousness of IBD, reduce recurrence, and provides a new strategy for the treatment of IBD.
