What causes inflammation?

Inflammation is caused by a variety of stimuli, including:

1. Infections: Bacterial, viral, and fungal infections can trigger an inflammatory response in the body.
2. Physical injury: Injuries to the tissue, such as cuts, sprains, or fractures, can result in inflammation.
3. Chemical irritants: Exposure to irritants such as pollution, tobacco smoke, and certain chemicals can cause inflammation.
4. Allergic reactions: Allergic reactions to substances such as pollen, pet dander, and certain foods can lead to inflammation.
5. Autoimmune disorders: In some cases, the body's immune system mistakenly attacks healthy tissues, leading to chronic inflammation.
6. Chronic diseases: Chronic diseases such as diabetes, heart disease, and cancer can also be associated with chronic inflammation.
7. Stress: Chronic stress can increase the production of certain hormones that can lead to inflammation.

In addition to these, there are other factors that can contribute to inflammation, including diet, sedentary lifestyle, and aging. It is important to manage these factors to reduce the risk of developing inflammation and its associated diseases.
