Elevated Fecal Zonulin

Elevated fecal zonulin levels indicate an increase in the production of a protein called zonulin in the intestines. Zonulin plays a role in regulating the permeability of the intestinal lining. Elevated levels of zonulin may suggest an increased intestinal barrier permeability, often referred to as "leaky gut." This condition can allow the passage of unwanted substances from the intestines into the bloodstream, which may contribute to various health issues, including gastrointestinal disorders and autoimmune diseases.
