What to do About a Leaky Gut
Leaky gut is also known as increased intestinal permeability. It's when the cells lining our intestines (gut) separate a bit from each other. They're supposed to be nice and tightly joined to the cell beside it; this is to allow certain things into our bodies (like nutrients), and keep other things out.
When the tight junctions between intestinal cells weaken it can cause the gut to be more permeable - leakier - than normal. When this happens, it allows things into our bodies that should not get in; things like large pieces of protein, toxins, or even bacteria and waste.
When substances that shouldn't be there, get into our bloodstream through the "leaks" in our gut, our immune system kicks in. These leaked bits mimic a food allergy, and our body reacts accordingly. It mounts a response to try to attack the invaders, and this causes inflammation.
Leaky gut is associated with a number of issues including food allergies, celiac disease, autoimmune diseases (e.g., Inflammatory Bowel Disease, Hashimoto's, asthma, type 1 diabetes, acne, eczema), joint pain, and neurological problems (e.g., multiple sclerosis). Some research shows that leaky gut might contribute to or worsen these conditions.
