3. Inflammation: The Root of Redness and Breakouts

Chronic gut inflammation often reveals itself on the skin as redness, swelling, or stubborn breakouts. For example, people with irritable bowel syndrome (IBS) or other digestive flare-ups frequently notice simultaneous eczema or acne issues. When the gut lining is irritated, it may leak inflammatory molecules into the bloodstream, worsening skin problems. Adopting an anti-inflammatory diet—rich in leafy greens, berries, and omega-3 fats—can help calm both digestive and skin symptoms.
