Lupus is a group of autoimmune diseases. The form most often discussed is systemic lupus erythematosus (SLE), which can cause inflammation and affect different parts of the body. Lupus is a complex condition and can look very different from one person to another.
Symptoms and flares
Possible symptoms include fatigue, joint pain or swelling, fever, skin rashes, hair loss, mouth sores, and sensitivity to sunlight. Some people may have involvement of organs such as the kidneys, heart, lungs, blood, or nervous system. Symptoms may become more active during periods often called flares and may lessen during periods of lower disease activity. Not every person has the same symptoms or pattern.
Diagnosis is not based on one symptom or test
Lupus can be difficult to diagnose because symptoms overlap with other conditions and may come and go. Healthcare professionals consider a person's history, examination, and a combination of laboratory or other tests. A single positive antibody result by itself does not establish a diagnosis. This page cannot assess symptoms or interpret test results.
Support, visibility, and access
People living with lupus may need support with fatigue, pain, appointments, work or school flexibility, and fluctuating symptoms that others cannot see. Ask what accommodations help. Avoid assumptions based on appearance or on another person's experience with lupus.
