Lupus (Systemic Lupus Erythematosus)
Lupus is a chronic autoimmune disease where the body's immune system mistakenly attacks healthy tissues and organs. It causes widespread inflammation and can affect the skin, joints, kidneys, and brain.
Overview
Lupus is a chronic autoimmune disease where the body's immune system mistakenly attacks healthy tissues and organs. It causes widespread inflammation and can affect the skin, joints, kidneys, and brain.
Understand this condition
In a healthy body, the immune system produces antibodies to fight off viruses and bacteria. In lupus, the immune system loses the ability to tell the difference between foreign invaders and the body's own healthy cells. It creates autoantibodies that attack various tissues, causing inflammation and damage throughout the body.
Why it happens
Lupus likely results from a combination of genetics and environmental triggers like UV light or infections. These triggers cause the immune system to misfire, leading to a cycle of chronic inflammation. The disease typically involves alternating periods of flares, where symptoms are active, and remission, where symptoms fade.
