What is lupus?
Lupus is a chronic, autoimmune disease that can damage any part of the body (skin, joints, and/or organs inside the body). Chronic means that the signs and symptoms tend to last longer than six weeks and often for many years.
In lupus, something goes wrong with your immune system, which is the part of the body that fights off viruses, bacteria, and germs ("foreign invaders," like the flu). Normally our immune system produces proteins called antibodies that protect the body from these invaders. Autoimmune means your immune system cannot tell the difference between these foreign invaders and your body’s healthy tissues ("auto" means "self") and creates autoantibodies that attack and destroy healthy tissue. These autoantibodies cause inflammation, pain, and damage in various parts of the body.
Lupus is also a disease of flares (the symptoms worsen and you feel ill) and remissions (the symptoms improve and you feel better).
These are some additional facts about lupus that you should know:
Lupus is not contagious, not even through sexual contact. You cannot "catch" lupus from someone or "give" lupus to someone.
Lupus is not like or related to cancer. Cancer is a condition of malignant, abnormal tissues that grow rapidly and spread into surrounding tissues. Lupus is an autoimmune disease, as described above.
Lupus is not like or related to HIV (Human Immune Deficiency Virus) or AIDS (Acquired Immune Deficiency Syndrome). In HIV or AIDS the immune system is underactive; in lupus, the immune system is overactive.
Lupus can range from mild to life-threatening and should always be treated by a doctor. With good medical care, most people with lupus can lead a full life.
Our research estimates that at least 1.5 million Americans have lupus. The actual number may be higher; however, there have been no large-scale studies to show the actual number of people in the U.S. living with lupus.
More than 16,000 new cases of lupus are reported annually across the country.
It is believed that 5 million people throughout the world have a form of lupus.
Lupus strikes mostly women of childbearing age (15-44). However, men, children, and teenagers develop lupus, too. Most people will develop lupus between the ages of 15-44.
Women of color are two to three times more likely to develop lupus than Caucasians.
People of all races and ethnic groups can develop lupus.
Symptoms
No two cases of lupus are exactly alike. Signs and symptoms may come on suddenly or develop slowly, may be mild or severe, and may be temporary or permanent. Most people with lupus have mild disease characterized by episodes — called flares — when signs and symptoms get worse for a while, then improve or even disappear completely for a time.
The signs and symptoms of lupus that you experience will depend on which body systems are affected by the disease. The most common signs and symptoms include:
Fatigue and fever
Joint pain, stiffness and swelling
Butterfly-shaped rash on the face that covers the cheeks and bridge of the nose
Skin lesions that appear or worsen with sun exposure (photosensitivity)
Fingers and toes that turn white or blue when exposed to cold or during stressful periods (Raynaud's phenomenon)
Shortness of breath
Chest pain
Dry eyes
Headaches, confusion and memory loss
When to see a doctor
See your doctor if you develop an unexplained rash, ongoing fever, persistent aching or fatigue.
