Some people with lupus (systemic lupus erythematosus, or SLE) develop complications with internal organs, such as the kidney, heart or lungs.

Lupus affects different age groups at different rates. The majority of people with lupus develop the disease between ages 15 and 45. Women account for 85% of diagnosed lupus cases.

If you have lupus (systemic lupus erythematosus, or SLE), you may be extremely tired, have skin rashes, or have joint pain. If the disease is more serious, you may have problems with your kidneys, heart, lungs, blood, or nervous system.

If you have been diagnosed with lupus, call 911 or other emergency services immediately if you have chest pain that is crushing or squeezing, occurs with sweating or nausea, and has not been previously diagnosed.
