Although we may not realize it, our gut is responsible for much of our body, affecting everything from digestion to mood. When something is amiss in the gut, such as an overly-permeable intestine (also known as Leaky Gut Syndrome), it can impact many facets of your health. There are number of signs of Leaky Gut Syndrome, and not all of them have to do with just stomach issues.
When our gut is healthy, the intestines are only slightly permeable, allowing small quantities of water and nutrients to pass through the gut’s thin barrier and into the bloodstream. "This process is a normal and necessary part of digestion, and an essential step in nourishing the body to produce healthy, well-nourished cells," gastroenterologist Dr. Liz Cruz, tells Bustle. "However, when the holes in the intestinal wall get too big, large molecules, such as gluten and casein (in addition to other foreign microbes) escape into the bloodstream and start to spread all over the body." The body reacts to this by causing systemic inflammation throughout, since it begins to treat these molecules as foreign bodies.
But some believe that a leaky gut is actually a symptom of a greater issue, not the cause. Despite this debate, there are a number of symptoms that do co-occur with a "leaky gut," and it's worth paying attention to improving your gut health regardless.
