Leaky gut syndrome is a hypothetical, medically unrecognized condition.[1]

Unlike the scientific phenomemon of increased intestinal permeability ("leaky gut"),[1][2] claims for the existence of "leaky gut syndrome" as a distinct medical condition come mostly from nutritionists and practitioners of alternative medicine.[1][3][4] Proponents claim that a "leaky gut" causes chronic inflammation throughout the body that results in a wide range of conditions, including chronic fatigue syndrome, rheumatoid arthritis, lupus, migraines, multiple sclerosis, and autism.[1][3] As of 2016, there is little evidence to support the hypothesis that leaky gut syndrome directly causes this wide array of diseases.[1][5]

Stephen Barrett has described "leaky gut syndrome" as a fad diagnosis and says that its proponents use the alleged condition as an opportunity to sell a number of alternative-health remedies – including diets, herbal preparations, and dietary supplements.[4] In 2009 Seth Kalichman wrote that some pseudoscientists claim that the passage of proteins through a "leaky" gut is the cause of autism.[6] The belief that a "leaky gut" might actually cause autism is popular among the public, but the evidence is weak and what evidence exists is conflicting.[7]

Advocates tout various treatments for "leaky gut syndrome", such as dietary supplements, probiotics, herbal remedies, gluten-free foods, and low-FODMAP, low-sugar, or antifungal diets, but there is little evidence that the treatments offered are of benefit.[1] None have been adequately tested to determine if they are safe and effective for this purpose.[3] The U.K. National Institute for Health and Care Excellence (NICE) does not recommend the use of special diets to manage the main symptoms of autism.[1]
