Systemic lupus erythematosus (SLE) is a complex autoimmune disease characterized by inflammation and tissue damage caused by the immune system attacking healthy cells and tissues. It can affect various organs and systems in the body, including the skin, joints, kidneys, heart, and lungs. SLE is more common in women and tends to onset during childbearing years, although it can occur at any age. The exact cause of SLE is not well understood, but a combination of genetic, environmental, and hormonal factors is believed to play a role in its development. Treatment for SLE typically involves medications to control symptoms and prevent flare-ups, as well as lifestyle modifications to manage the disease. Ongoing research in the field of SLE aims to further understand the underlying mechanisms of the disease, improve diagnostic tools, and develop more effective treatments.
