Inflamation illustration

Inflammation is the body's natural response to injury or infection. It involves the immune system reacting to harmful stimuli, such as pathogens, damaged cells, or irritants. The main symptoms of inflammation are redness, heat, swelling, pain, and loss of function. These occur because blood vessels widen to increase blood flow, allowing immune cells to reach and heal the affected area. While inflammation helps protect the body, chronic inflammation can lead to various diseases, such as arthritis or heart disease.
