serositis

Serositis is an inflammation of the tissues that line certain internal organs and body cavities, such as the chest (pleura), abdomen (peritoneum), or around the heart (pericardium). This inflammation can cause symptoms like pain, swelling, and discomfort, often in areas such as the chest or abdomen. It can result from autoimmune diseases, infections, or other medical conditions. Serositis signifies that the body's immune system is reacting against these linings, leading to inflammation that may require medical treatment to manage symptoms and address the underlying cause.
