Leaky Gut: Causes, Symptoms, and Management

When dealing with Leaky Gut, a condition where the intestinal lining becomes overly permeable, letting undigested particles and toxins slip into the bloodstream. Also known as increased intestinal permeability, it often triggers a cascade of health issues that many people overlook.

At the core of this condition is Intestinal Permeability, the measure of how tightly the gut wall controls what passes through. When tight junctions loosen—due to poor diet, chronic stress, infections, or certain medications—the barrier loses its selectivity. This loss sets the stage for unwanted molecules to enter the circulatory system, which can spark immune reactions and nutrient deficiencies.

Another key player is the Gut Microbiome, the community of bacteria, fungi, and viruses that live in the digestive tract. A balanced microbiome produces short‑chain fatty acids that reinforce the gut lining. When the microbial mix tilts toward harmful species, those protective compounds dwindle, making the barrier more vulnerable to leaks.

Once the barrier is compromised, Inflammation, the body’s natural response to perceived threats often spikes. Persistent low‑grade inflammation can irritate the lining, further widening the gaps. Over time, this chronic state may contribute to Autoimmune Disease, conditions where the immune system mistakenly attacks healthy tissue. Researchers frequently link leaky gut to thyroid disorders, rheumatoid arthritis, and skin conditions like eczema.
