Lupus is a serious autoimmune disease, which means your immune system attacks healthy cells by mistake. It’s also chronic, meaning it lasts a long time and requires long-term treatment. Lupus is one of the most complex autoimmune diseases there is. It affects each person differently with symptoms that are sometimes hard to detect and differ from patient to patient. This makes the disease hard to diagnose and arriving at effective treatments very challenging. It’s even been called “the disease with 1,000 faces.” But there are many more faces and minds determined to cure lupus.
