Systemic lupus erythematosus is an autoimmune disease and is chronic. The cause of the disease is mostly unclear, but studies have shown that it is related to genetics, environmental pollution, viral infections, hormone levels, and other factors. As an autoimmune disease, it cannot be completely cured. The main purpose of treatment is to control symptoms, delay the onset of complications, and improve the quality of life. The preferred treatment involves corticosteroids. The dosage should be adjusted according to the condition; after stabilizing, the dosage should gradually be reduced to a small maintenance dose. It is important to continue the medication even during maintenance therapy, as discontinuing the medication can lead to a recurrence of the disease. Additionally, chilling, fatigue, infection, and sun exposure can all trigger the activity of lupus, so it is important to be cautious in daily life. (Please use medication under the guidance of a doctor.)
