Systemic lupus erythematosus is an autoimmune disease that cannot be cured. It can only be managed with medications to control the progression of the disease, prevent relapses, and delay the onset of complications, which is the main purpose of treatment. The primary treatment options are corticosteroids and immunomodulators. Their main side effects include increased risk of infection and lowered immunity. Therefore, during routine care, it is essential to pay attention to personal hygiene, especially respiratory and urinary tract cleanliness, frequently change clothes, bathe regularly, prevent skin infections, and wear masks in crowded or public places. Additionally, it is important to avoid excessive sun exposure and engage in appropriate exercise to enhance immunity. (Note: Medications should be used under the guidance of a doctor.)
