This is a condition where the lining of your intestine becomes more permeable than it should be. Normally, this lining acts as a barrier, controlling what gets absorbed into the bloodstream. But with leaky gut, this barrier becomes compromised, allowing toxins, undigested food particles, and bacteria to pass into the bloodstream. If you suffer from chronic health issues like autoimmune diseases, allergies or asthma it is likely you have leaky gut.
