Lupus is a complex autoimmune disorder that can range from mild to life-threatening. While it has been around for centuries, the diagnosis and treatment can get overlooked by both patients and clinicians alike. Symptoms of lupus can range in severity and include fever, joint pain, fatigue, rashes, hair loss, mouth ulcers, and more. If left undetected and thus untreated, it can lead to organ damage and possible death. It’s important to recognize the potential signs of this disease so you can get an accurate diagnosis quickly if needed.
