Systemic lupus erythematosus is a multi-organ, multi-system disease that mainly affects the skin and internal organs, as well as the blood system, and is a common type of immune system disease. It is also a common type of immune system disease. Patients with lupus can eat foods such as cucumber, which have no effect on lupus disease. In addition to clinical symptoms, the diagnosis of SLE also depends on relevant laboratory tests, such as positive autoantibodies against nuclear antibody, anti-double-stranded DNA and Smith antibody. Therefore, the treatment needs to be under the guidance of rheumatologists, regular medication, and regular dose reduction. In the process of testing lupus, it is important to prevent complications such as cold, flu, inflammation and infection.
