What Are Inflammatory Diseases?
Inflammatory diseases are conditions caused by chronic immune system dysregulation, where the body mistakenly attacks its own tissues. These diseases include:
- Rheumatoid arthritis
- Inflammatory bowel disease (Crohn’s disease & ulcerative colitis)
- Psoriasis and psoriatic arthritis
- Asthma and chronic respiratory inflammation
- Multiple sclerosis
These conditions require long-term treatment and monitoring, making them a key focus area in modern healthcare systems.
