Inflammation can be classified into two main types: acute and chronic. Acute inflammation is a short-term response that usually resolves within a few days. It is characterized by the rapid onset of symptoms and is primarily aimed at eliminating the injurious agents and initiating tissue repair. Chronic inflammation, on the other hand, is a prolonged response that can last for weeks, months, or even years. It often results from persistent infections, autoimmune diseases, or long-term exposure to irritants. Chronic inflammation can lead to tissue damage and fibrosis.
