Chronic inflammation
In this case, your body continues to send inflammatory cells even when there is no outside danger. For example, in rheumatoid arthritis inflammatory cells and substances attack joint tissues leading to inflammation coming and going and can result in severe damage to joints with pain and deformities.
Chronic inflammation can occur if a person has:
- Sensitivity: When the body detects something that shouldn’t be there, inflammation results. An allergy may develop as a result of hypersensitivity to an external stimulus.
- Autoimmune disorders: In psoriasis [1], the immune system unintentionally targets normal, healthy tissue.
- Exposure: Chronic inflammation can occasionally be brought on by prolonged, low-level exposure to an irritant, such as an industrial chemical.
- Acute inflammation that persists: In some circumstances, an individual may not fully heal from acute inflammation. This can occasionally cause chronic inflammation.
- Autoinflammatory disorders: A genetic factor affects the way the immune system works, as in Behçet’s disease [2].
