What should I know about leaky gut heilen?

The concept of 'leaky gut' (increased intestinal permeability) is controversial in mainstream medicine. While it is recognized that intestinal barrier function can be impaired in conditions like celiac disease, IBD, or severe infections, the idea that a 'leaky gut' is a standalone disease causing systemic symptoms lacks robust clinical evidence. The MyBody-X knowledge context provided does not address leaky gut directly; it covers DNA tests for metabolism, allergies, and drug response, none of which validate or refute leaky gut claims. Therefore, evidence for healing leaky gut via specific diets or supplements is weak and largely based on mechanistic reasoning or marketing. Conservative advice: support gut health with a balanced diet rich in fiber, fermented foods, and adequate hydration; avoid excessive alcohol and NSAIDs. If you suspect a gut issue, consult a gastroenterologist rather than relying on direct-to-consumer tests. Evidence grade: marketing/unclear.
