Intestinal Permeability

Evidence-informed definition Updated July 23, 2024 How to cite this entry

Intestinal permeability is a functional feature of the intestinal barrier that allows for the exchange of solutes and fluids between the intestinal lumen and mucosa (Lee, 2015). Various factors, including dietary components, physiologic stressors, or strenuous exercise, cause alterations in intestinal permeability. This may result in the loss of intestinal wall integrity, allowing electrolytes, water, and pathogenic bacteria to enter systemic circulation, triggering inflammation and various diseases (Hollander & Kaunitz, 2019; Stewart et al., 2017).
