What is lupus? My sister was just told this is what is causing her problems. I've heard of it but I don't really know what it is.
Lupus otherwise known as systemic lupus erythematosus (SLE) is an autoimmune disorder that can affect many parts of the body including the skin, joints, and organs.
Autoimmune means the immune system isn't working properly. It recognizess body parts as foreign to itself. Then the immune system launches an attack against normal body tissue.
There are two main types of lupus. The first is discoid (also known as cutaneous) lupus. Discoid lupus only affects the skin. Systemic lupus erythematosus (SLE) affects the skin and other tissues as mentioned.
Either type can be mild but SLE is chronic and can become progressive. Researchers are beginning to use genetic testing to identify subtypes. This will help establish the diagnosis earlier and direct treatment more specifically.
