There are many symptoms of SLE, which can affect everything from head to toe. Common symptoms include fever, mouth ulcers, rash, hair loss, and joint pain. The rash is the more specific symptom and includes butterfly-shaped erythema on the cheeks as well as discoid red shifts with a slightly raised periphery. In addition, the kidneys, blood system, nervous system, cardiovascular, lungs, and gastrointestinal tract may be affected. Many patients with mild disease in the early stages of the disease often think that mouth ulcers are caused by “fatigue” or “fire” and that the rash is an “allergy”, and so on. This is not a minority of cases. You should be alerted to lupus erythematosus when the following phenomena occur at the same time: recurrent fever, allergy to sunlight, frequent mouth ulcers, butterfly-shaped red spots on the face or other parts of the body, recurrent joint pain, swelling, red blood cells or protein in the urine, and significant fatigue. The most serious problems include destruction of brain tissue, hemoptysis, uremia, severe anemia, infection, and blood clots in multiple blood vessels throughout the body. Some women of childbearing age suffer from repeated pregnancy failures, which are caused by the disease blocking the maternal nutrient supply to the fetus or by abnormal components in the mother’s body damaging the fetal internal organs. SLE can be very aggressive, but with proper treatment, the disease will gradually resolve. It should be noted that although medication can improve the disease in most cases, the function of the more damaged organs cannot be fully restored, therefore, early diagnosis and reasonable treatment are important for SLE.
