Essentially, leaky gut syndrome (âintestinal hyperpermeabilityâ) is condition that happens as a consequence of intestinal tight junction malfunction. These âtight junctionsâ are the gateway between your intestines and what is allowed to pass into the blood stream.
A possible cause of leaky gut is increased intestinal permeability or intestinal hyperpermeability. That could happen when tight junctions in the gut, which control what passes through the lining of the small intestine, don't work properly. That could let substances leak into the bloodstream.
