Inflammation is the body's response to harmful stimuli, such as pathogens, damaged cells, or irritants. When inflammation occurs, the body's immune system activates to begin the healing process.
There are five main signs of inflammation:
- Redness - Increased blood flow causes blood vessels to dilate and become more visible.
- Swelling - Histamines released by damaged cells allow plasma to leak out of blood vessels into surrounding tissues.
- Heat - More blood flowing to the inflamed area increases temperature.
- Pain - Chemicals from immune cells sensitize nerves, making the area more sensitive.
- Loss of function - Impaired movement attempts to make the area rest and heal.
Inflammation serves the important purpose of alerting the body to injury or infection and getting the healing process started quickly. There are two main types:
Acute inflammation occurs rapidly and intensely in response to trauma, but is temporary. Signs usually resolve within days or weeks. This helps the body return to normal function.
Chronic inflammation persists over longer periods of time, ranging from weeks to years. It can cause new tissue damage and lead to diseases like rheumatoid arthritis, heart disease, or diabetes. Treating the underlying cause can stop chronic inflammation.
The inflammatory process involves various cells, mediators, and processes:
- Mast cells release histamines and other inflammatory mediators.
- Dilated blood vessels allow more immune system cells into tissues.
- Phagocytes like neutrophils consume pathogens and cell debris.
- Cytokines signal immune cells to act.
- Prostaglandins intensify the response.
Inflammation is usually a helpful, temporary immune reaction to injury or infection. But prolonged, dysregulated inflammation can damage tissues and contribute to disease. Controlling inflammation is key for managing many conditions.
