Have you recently developed frequent mouth ulcers? Have you recently developed facial erythema? Do you have a red rash when you are in the sun? Have you inexplicably started to suffer from severe hair loss? Are you experiencing unexplained joint pain? Have you ever thought of seeking medical help for these symptoms? If you have any of these symptoms, your doctor warns you: don’t take it lightly, because you may have a disease called “lupus erythematosus”! SLE is an autoimmune disease, and China is a country with a high prevalence of lupus, with about 70 out of every 100,000 people suffering from this disease, mainly affecting young women, with sun allergy and mouth ulcers being the most common symptoms. SLE can affect many important organs in human body, and if not treated reasonably, it will cause many sequelae and even endanger life. Some patients are also reluctant to receive treatment due to lack of proper understanding of the disease, fear of the disease, or doubts about the treatment and medication, and fear of side effects.
