Lupus (systemic lupus erythematosus) is a long-term disease that can cause inflammation, pain, and tissue damage in your body. It is an autoimmune disease. This means the immune system attacks its own tissues. Lupus may cause problems with your skin, kidneys, heart, lungs, nerves, or blood cells. There are other types of lupus, but systemic lupus erythematosus is the most common and most serious type.
When you have lupus symptoms, you are having flares or relapses. When your symptoms get better, you are in remission. Lupus may get worse very quickly. There is no way to tell when a flare will happen or how bad it will be. When you have a lupus flare, you may have new symptoms as well as symptoms you have had in the past.
Learn your body's signs of a flare, such as joint pain, a rash, a fever, or being more tired. When you see any of these signs, take steps to control your symptoms.

When you have lupus symptoms, you are having flares or relapses. When your symptoms get better, you are in remission. Lupus can't be cured, but home treatment and medicine can help control the symptoms.
The course of lupus varies by individual. It's hard to predict because symptoms come and go. You may not notice the symptoms for a long time. But sometimes lupus develops rapidly.
The times when you have symptoms are called flares or relapses. Remissions are times when your symptoms are under control. Flares and remissions can occur abruptly and without clear cause. There is no way to predict how bad a flare will be or how long it will last. During a flare, you may have new symptoms plus those you have had in the past.
Children can get lupus. But it usually develops in the teen years or later. When vital organs are involved, lupus in children appears to be more severe than in adults.
There are also concerns if you have lupus and are pregnant. Some people with lupus have kidney and heart problems. But most people live a normal or near-normal lifespan.
Lupus rash is red or purplish and mildly scaly, appearing on the face (butterfly or malar rash) and symmetrically on the arms, fingers, or legs.
Lupus treatment can be complicated. Symptoms vary, and flares and remissions can still happen. But the goal of treatment is to find a balance between controlling your symptoms, preventing organ damage, and having fewer side effects.
Treatment for mild lupus may include:
If your lupus causes or threatens organ damage, is life-threatening, or has a serious impact on your quality of life, you may also need to take:
Some people get serious kidney disease that can't be controlled with medicine. They may need dialysis or a kidney transplant.
There is currently no way to prevent lupus.
There is no single test for lupus. Because lupus affects different people in different ways, it can be hard to diagnose. It can take time for symptoms to develop. And sometimes it takes weeks to years to diagnose.
Your doctor will give you an exam and ask questions about your symptoms and past health. He or she will check for certain criteria to help diagnose lupus. These include a butterfly rash, joint swelling, fatigue, being sensitive to sunlight, and mouth or nose sores.
If you have lupus symptoms and you have a positive antinuclear antibody test result, you may not need more testing.
If your doctor feels that you do need more tests, you may have one or more of these tests:
To evaluate initial symptoms and treat mild lupus, you can talk with:
For long-term management of complicated lupus, talk with:
For more complicated cases of lupus, a rheumatologist is usually the primary doctor. Other specialists are consulted as needed.
The chances of getting lupus are higher in people who:
Certain things can trigger lupus flares. These may include:
Lupus (systemic lupus erythematosus) doesn't usually affect a woman's ability to conceive. But if you are having a lupus flare or are taking corticosteroid medicines, you may have irregular menstrual cycles. This can make it hard to plan a pregnancy.
If you plan to have a baby or are already pregnant, it's very important that you and your doctor discuss how lupus may affect your pregnancy.
Talk with your doctor about which medicines you can take during pregnancy.
If you have miscarried before, expect that your pregnancy will be closely watched. Talk to your doctor about whether you have tested positive for antiphospholipid antibodies. If so, anticoagulant treatment may improve your chances of having a healthy pregnancy.
People who have lupus may develop problems with different organs and systems of the body. These include problems with:
There may be changes in the blood cells, anemia, and changes to organs related to circulation, such as the spleen or lymph nodes. Some people with lupus produce antibodies that attack certain blood-clotting factors, causing the blood to clot too easily. This is called antiphospholipid syndrome (APS). It can lead to mild or severe problems. Some of these are stroke, heart attack, deep vein thrombosis, miscarriage, and preeclampsia.
Inflammation of the tissues around the lungs may cause no symptoms. But sometimes it can cause painful breathing, coughing, or chest pain.
Inflammation of the sac around the heart is the most common lupus-related heart problem. There may also be hardening of the arteries and diseases of the heart valves.
People who have lupus might notice swelling of the legs and ankles. They might have abnormal lab results when their urine is tested. Some people develop serious kidney disease.
Some of these problems include mild memory loss, headaches, problems with vision, muscle weakness, and loss of feeling in the feet and hands. Many people who have lupus become anxious or depressed. They might have delusions, hallucinations, or episodes of manic behavior.
Lupus is an autoimmune disease. This means that the body's natural defense system (immune system) attacks your body's healthy tissues instead of attacking only things like bacteria and viruses. This causes inflammation.
Some people with lupus have only mild symptoms. But the disease is lifelong and can become severe. Lupus may cause problems with your skin, kidneys, heart, lungs, nerves, or blood cells.
Systemic lupus erythematosus is the most common and most serious type of lupus. But there are other types of lupus. They include discoid or cutaneous lupus, drug-induced systemic lupus, and neonatal lupus.
The exact cause of lupus isn't known. Experts believe that some people are born with certain genetic mutations that affect their immune systems and make them more likely to get lupus.
