Lupus (Systemic Erythematosus)
Lupus is a chronic autoimmune disease where the body's immune system attacks its own tissues and organs. It causes widespread inflammation and can affect the joints, skin, kidneys, blood cells, brain, heart, and lungs.
Overview
Lupus is a chronic autoimmune disease where the body's immune system attacks its own tissues and organs. It causes widespread inflammation and can affect the joints, skin, kidneys, blood cells, brain, heart, and lungs.
Understand this condition
The immune system usually produces proteins called antibodies to protect against germs. In lupus, the body produces autoantibodies that attack its own healthy cells and tissues instead. This causes inflammation and can damage the skin, joints, kidneys, and blood cells.
Why it happens
Lupus occurs due to a combination of genetics and environmental triggers like UV light or stress. These factors cause the immune system to lose its ability to distinguish between invaders and healthy cells. The disease typically involves cycles of inflammation that may gradually lead to permanent organ scarring if left untreated.
