Lupus is an inflammatory disease caused when the immune system attacks its own tissues. The immune system is designed to attack foreign substances in the body. If you have lupus, something goes wrong with your immune system and it attacks healthy cells and tissues. This can damage many parts of the body such as the:
- Blood vessels
There are many kinds of lupus. The most common type, systemic lupus erythematosus, affects many parts of the body. Other types of lupus are:
- Discoid lupus erythematosus—causes a skin rash that doesn’t go away
- Subacute cutaneous lupus erythematosus—causes skin sores on parts of the body exposed to sun
- Drug-induced lupus—can be caused by medications
- Neonatal lupus—a rare type of lupus that affects newborns.
Anyone can get lupus, but it most often affects women. Lupus is also more common in women of African American, Hispanic, Asian, and Native American descent than in Caucasian women.
The cause of lupus is not known. Research suggests that genes play an important role, but genes alone do not determine who gets lupus. It is likely that many factors trigger the disease.
Symptoms of lupus vary, but some of the most common symptoms of lupus are:
- Pain or swelling in joints
- Muscle pain
- Fever with no known cause
- Red rashes, most often on the face
- Chest pain when taking a deep breath
- Hair loss
- Pale or purple fingers or toes
- Sensitivity to the sun
- Swelling in legs or around eyes
- Mouth ulcers
- Swollen glands
- Feeling very tired.
- Anemia (a decrease in red blood cells)
- Dizzy spells
- Feeling sad
Symptoms may come and go. The times when a person is having symptoms are called flares, which can range from mild to severe. New symptoms may appear at any time.
There is no single test to diagnose lupus. It may take months or years for a doctor to diagnose lupus. Your doctor may use many tools to make a diagnosis:
- Medical history
- Complete exam
- Blood tests
- Skin biopsy (looking at skin samples under a microscope
- Kidney biopsy (looking at tissue from your kidney under a microscope).
You may need special kinds of doctors to treat the many symptoms of lupus. Your health care team may include:
- A family doctor
- Rheumatologists—doctors who treat arthritis and other diseases that cause swelling in the joints
- Clinical immunologists—doctors who treat immune system disorders
- Nephrologists—doctors who treat kidney disease
- Hematologists—doctors who treat blood disorders
- Dermatologists—doctors who treat skin diseases
- Neurologists—doctors who treat problems with the nervous system
- Cardiologists—doctors who treat heart and blood vessel problems
- Endocrinologists—doctors who treat problems related to the glands and hormones
- Social workers.
Your doctor will develop a treatment plan to fit your needs. You and your doctor should review the plan often to be sure it is working. You should report new symptoms to your doctor right away so that treatment can be changed if needed.
- Prevent flares
- Treat flares when they occur
- Reduce organ damage and other problems.
- Reduce swelling and pain
- Prevent or reduce flares
- Help the immune system
- Reduce or prevent damage to joints
- Balance the hormones.
In addition to medications for lupus itself, sometimes other medications are needed for problems related to lupus such as high cholesterol, high blood pressure, or infection. Alternative treatments are those that are not part of standard treatment. No research shows that this kind of treatment works for people with lupus. You should talk to your doctor about alternative treatments.
It is vital that you take an active role in your treatment. One key to living with lupus is to know about the disease and its impact. Being able to spot the warning signs of a flare can help you prevent the flare or make the symptoms less severe. Many people with lupus have certain symptoms just before a flare, such as:
- Feeling more tired
- Stomach ache
- Look for changes in symptoms
- Predict and prevent flares
- Change the treatment plan as needed
- Detect side effects of treatment.
It is also important to find ways to cope with the stress of having lupus. Exercising and finding ways to relax may make it easier for you to cope. A good support system can also help. A support system may include family, friends, community groups, or doctors. Many people with lupus have found support groups to be very useful. Besides providing support, taking part in a support group can make you feel better about yourself and help you to keep a good outlook.
- Have less pain
- Make fewer visits to the doctor
- Feel better about themselves
- Remain more active.
