The most prominent symptom of Systemic Lupus Erythematosus (SLE) is a rash on the face, especially across the bridge of the nose and cheeks, known as a "butterfly" or "malar" rash. Other common symptoms of SLE include fatigue, joint pain and swelling, fever, hair loss, anemia, mouth ulcers, and sensitivity to sunlight.
The rash is one of the most visible signs of SLE, and may be present even when other symptoms are not. It is often red, scaly, and may cause itching or burning. In some cases, it may become worse when exposed to sunlight or artificial lighting.
Other symptoms of SLE may include anemia, which is a decrease in red blood cells; joint pain and swelling; fever; hair loss; skin lesions; and sensitivity to light. Some people may also experience chest pain, abdominal pain, and difficulty breathing.
In some cases, SLE can cause kidney failure, stroke, or heart attack. It is important to see a doctor right away if any of these symptoms occur. Early diagnosis and treatment of SLE can help to reduce the risk of these serious complications.
