Leaky gut, also known as increased intestinal permeability, is a condition where the lining of the small intestine becomes damaged or overly porous, allowing undigested food particles, toxins, and bacteria to "leak" through the gut wall and enter the bloodstream.
How it works:
-
Normally, the gut lining acts as a tight barrier, letting nutrients in and keeping harmful substances out.
-
With leaky gut, the tight junctions between intestinal cells loosen.
-
This may trigger inflammation and an immune response, which some researchers believe could contribute to various health issues.
Possible symptoms associated with leaky gut:
-
Bloating, gas, or cramps
-
Food sensitivities
-
Fatigue
-
Joint pain
-
Skin issues like eczema
-
Brain fog
Conditions potentially linked (still under study):
-
Autoimmune diseases (e.g., Hashimoto’s, celiac disease)
-
IBS (Irritable Bowel Syndrome)
-
Chronic fatigue
-
Inflammatory bowel diseases (Crohn’s, ulcerative colitis)
Causes and contributors:
-
Chronic stress
-
Poor diet (especially high in sugar, alcohol, or processed foods)
-
Long-term use of NSAIDs or antibiotics
-
Gut infections or dysbiosis (imbalance in gut bacteria)
Controversy:
-
Not all medical professionals agree that “leaky gut” is a standalone diagnosis.
-
It’s recognized in research as part of gastrointestinal and immune function, but more studies are needed to clarify its role in chronic diseases.
Supportive steps (under medical guidance):
-
Eating a gut-friendly diet (e.g., rich in fiber, fermented foods, low in processed sugars)
-
Managing stress
-
Supporting gut flora with probiotics or prebiotics
-
Avoiding triggers like alcohol, gluten (if sensitive), or inflammatory foods
