Inflammation is part of the body’s healing process. However chronic inflammation causes many diseases and health conditions - "Without inflammation as a physiological response, wounds would fester, and infections could become deadly. However, if the inflammatory process goes on for too long or if the inflammatory response occurs in places where it is not needed, it can become problematic. Chronic inflammation has been linked to certain diseases such as heart disease or stroke, and may also lead to autoimmune disorders, such as rheumatoid arthritis and lupus. But a healthy diet and lifestyle can help keep inflammation under control.
Acute inflammation occurs after a cut on the knee, a sprained ankle or a sore throat. It's a short-term response with localized effects, meaning it works at the precise place where a problem exists.
Unlike acute inflammation, chronic inflammation can have long-term and whole-body effects. Chronic inflammation is also called persistent, low-grade inflammation because it produces a steady, low-level of inflammation throughout the body, as judged by a small rise in immune system markers found in blood or tissue."
