4. Leaky Gut Syndrome and Skin Sensitivities

Leaky gut syndrome occurs when the intestinal lining becomes permeable, allowing tiny food particles and toxins to escape into the bloodstream. This triggers immune reactions that can manifest as skin rashes, hives, or heightened sensitivities—much like an allergic response. For many, episodes of leaky gut coincide with new or worsening skin problems, such as dermatitis or unexplained irritations. Emerging evidence suggests that supporting gut barrier function may help reduce these immune-driven skin symptoms.
