Inflammatory Response: What It Is, Why It Happens, and How It Affects Your Health


An inflammatory response is the body's natural reaction to injury, infection, or irritation. It involves immune cells, chemical signals, and increased blood flow that produce redness, warmth, swelling, and sometimes pain. This response is essential for clearing threats and starting repair, but when it becomes chronic or out of balance, it can contribute to conditions from metabolic disorders to autoimmune issues. A healthy inflammatory response supports healing, and gut health plays a central role in moderating how strongly it’s triggered and how quickly it resolves. Signals that the inflammatory response is at work include persistent digestive discomfort, fatigue, joint stiffness, and skin issues. Risk factors that tilt the balance toward chronic inflammation include obesity, diets high in processed foods and added sugars, insufficient sleep, chronic stress, smoking, and aging. The gut microbiome is a key modulator: an imbalanced microbial community can amplify inflammatory signals, while a diverse, balanced microbiome helps keep the inflammatory response in check. The Gut Microbiome Health Index provides a concise 0–100 score to summarize gut health, alongside data on Bacteria abundances and Bacteria functions so you can compare against a healthy cohort. Learn more about how this works on the InnerBuddies microbiome test page. Practical steps to support healing and calm the inflammatory response include an anti-inflammatory lifestyle: fiber-rich plant foods, omega-3 fatty acids, polyphenols from berries and tea, and fermented foods that nourish beneficial bacteria. Regular physical activity, adequate sleep, stress management, and staying hydrated also help the body resolve inflammation.
