I: Diet Patients with lupus nephritis should get enough nutrients and energy, such as protein, vitamins, minerals and carbohydrates, with lightness being appropriate. Water and salt should be moderately restricted. Avoid large amounts of tobacco, alcohol or stimulating foods. Exercise can promote blood circulation, enhance cardiopulmonary function and maintain the intake of protein for muscles and bones. III: Avoid sunlight Lupus patients are sensitive to sunlight, which is caused by the beta wavelength of ultraviolet light, and should avoid sunlight as much as possible. 4: Prevention of infection Patients’ immunity is generally reduced due to the influence of the disease or the side effects of steroids or immunosuppressants, and they are very vulnerable to bacterial invasion and other infections of various organs. The common ones are respiratory tract infection, urinary tract infection, gastrointestinal tract infection, and wound infection. Therefore, it is important to pay attention to the cold and keep warm, and try to avoid getting cold and injuries. 5: Adjusting emotion Suddenly being diagnosed with lupus is a heavy blow to the patient mentally, and anxiety, depression, anger, guilt, denial and melancholy come one after another. Emotion and disease have an inseparable and mutual influence relationship. At this time, patients are faced with physical and psychological challenges. To win this battle, it is vital to keep the mood happy. At the same time family and friends need to provide love and support.
