Patients with lupus erythematosus should strengthen their own nursing care, which also has a very crucial role in the prognosis of the disease. Patients should be made to maintain an optimistic attitude and good mood to help them build up confidence to overcome the disease. Patients with mild disease should arrange their diet and living reasonably, such as eating more high-protein and nutrient-rich foods, except for celery and mushrooms, which can stimulate cellular immunity to trigger disease activities, and avoid eating chicken, duck, meat and seafood, etc. Pay attention to rest, sleeping for more than 8 hours at night and taking a nap for about 1 hour after lunch. Patients with photosensitivity should avoid sunlight when they go out. Those with different manifestations of lupus erythematosus can be cared for accordingly: 1. Facial erythema: Keep the face clean, wash the face with water frequently, and wet compress the erythema with warm water of about 30℃. Avoid using alkaline soap, poor quality cosmetics, etc. 2.Mouth and nasal mucous membrane ulcers: maintain oral hygiene, clean the mouth after meals, brush teeth with a soft toothbrush, and apply iodine glycerin locally. 3.Hair loss: Wash your hair with warm water and massage your scalp while washing. 4.Long-term bed rest: Pay attention to prevent bed sores, turn more often, keep the local area clean, pat the back to facilitate coughing up phlegm, and pay attention to the change of urine and stool. 5, pay attention to the side effects of drugs: such as black stools, skin acne, hip pain, blurred vision, etc., should be reflected to the responsible doctor in time to take measures. In a word, good nursing is very important to the development and recovery of lupus erythematosus, and sometimes it can even play a role that cannot be achieved by medicine.
