Why? The physicians credit the phenomenon with being one cause of a host of chronic health problems, from digestive issues and acne to autoimmune diseases like arthritis and psoriasis. And collectively these affect a huge number of people.  We got the scoop on this problem with the yuck-factor name that may be affecting your health.  WHAT IS LEAKY GUT? Leaky gut syndrome is known as “increased intestinal permeability” in the conventional medical world. “There are tight junctions between the cells of the gastrointestinal (GI) tract,” explains Christine Frissora, MD, a gastroenterologist at the Center for Advanced Digestive Care at NewYork-Presbyterian Hospital/Weill Cornell Medical Center. “These junctions decrease the permeability of the lining of the GI tract, so that bacteria and other toxins cannot enter the blood stream.” The problem occurs when those junctions are loosened, and bacteria and other harmful substances literally leak out of your small intestine into your blood stream, triggering an inflammatory reaction in the body. And that’s not a good thing.  Find out what causes a leaky gut—and what to do about it—with Well+GoodNYC’s Do You Have A Leaky Gut?
