Inflammation is a vital defense mechanism that protects the body from harmful stimuli such as pathogens, damaged cells, or irritants. It plays an essential role in healing and tissue repair. However, depending on duration and response, inflammation is categorized into two types: acute and chronic. Acute inflammation is rapid and short-term, aiming to eliminate the initial cause of injury and promote repair. Chronic inflammation, in contrast, is prolonged and often leads to tissue destruction and fibrosis. This paper aims to explain the main differences between acute and chronic inflammation, including their causes, cellular mechanisms, mediators, and clinical outcomes.
