Your intestinal walls are meant to prevent the penetration of harmful particles into the liver and body cells. However, increased gut lining permeability can lead to Leaky Gut Syndrome, allowing undigested food particles, toxins, and parasites to cross the intestinal walls. The condition leads to bowel issues, bloating, and skin issues. Your intestinal walls can weaken due to inflammation, making the lining more permeable. The leakage of larger molecules into the bloodstream can be detrimental.
