Systemic lupus erythematosus is a global autoimmune disease that can involve multiple systems and organs. The cause of the disease is unclear, and it cannot be completely cured; it can only be managed through medication. However, once the condition stabilizes, the medication dosage can be gradually reduced and maintained at a low dose. The preferred treatment is corticosteroids, but if there is damage to other organs, such as pulmonary interstitial fibrosis or renal damage and proteinuria, it is necessary to combine immunosuppressants. This is done to prevent recurrence of the disease and to manage complications that may arise during the reduction of steroids. Additionally, it is crucial to be cautious about sun protection, avoid oral contraceptives, and prevent exposure to cold and overexertion. (Please take medication under the guidance of a doctor.)
