What is Lupus?

Lupus is a disease that occurs when your body’s immune system attacks your own tissues and organs (autoimmune disease). Inflammation caused by Lupus can affect many different body systems — joints, skin, kidneys, blood cells, brain, heart, and lungs.

Lupus is often hard to diagnose because its symptoms can mimic other conditions, and no one test can confirm the diagnosis. Treatment for Lupus typically involves a combination of medication and lifestyle changes.

Types of Lupus

If you have Lupus, it is essential to be aware of the different diagnoses that can come with the disease. Here is a list of some of the more common Lupus diagnoses:

1. Systemic Lupus Erythematosus (SLE): This is the most common type of Lupus and can affect multiple systems in the body, including the skin, joints, kidneys, brain, and blood vessels. SLE can be mild or severe, and symptoms can come and go.

2. Discoid Lupus Erythematosus (DLE): This type of Lupus only affects the skin causing a rash that can lead to scarring. DLE is usually not as severe as SLE but can still be painful and uncomfortable.

3. Subacute Cutaneous Lupus Erythematosus (SCLE): SCLE is similar to DLE in that it affects the skin but usually appears as raised red patches that do not scar. SCLE can also cause joint pain and inflammation.

4. Drug-Induced Lupus: As the name suggests, this type of Lupus is caused by certain medications. It is often reversible once the offending medication is stopped.

5. Neonatal Lupus: This is a rare form of Lupus that can affect newborn babies. It is usually caused by antibodies from the mother that cross the placenta and can cause heart problems, a skin rash, or liver damage in the baby.

Lupus is a severe disease that should be diagnosed and treated by a medical professional. If you think you may have Lupus, make an appointment with your doctor to discuss your symptoms and get started on the road to treatment and management.

Symptoms of Lupus

If you have Lupus, you may experience a wide range of symptoms. These can range from mild to severe and can come and go. They may also change over time.

The most common symptoms are:

• Fatigue
• Joint pain and stiffness
• Skin rashes
• Fever
• Anemia (low red blood cell count)
• Swelling (edema) in feet, legs, hands, and face
• Sun sensitivity (photosensitivity)
• Mouth ulcers
• Kidney problems
Other less common symptoms include:

• Chest pain or shortness of breath with activity
• Memory problems or difficulty concentrating (“brain fog”)
• Depression or anxiety
• Blood clots

Some people with Lupus also experience what is called “lupus flare.” This is when symptoms suddenly get worse. A lupus flare can be triggered by infection, stress, or other factors.

How Lupus is Diagnosed

No one test can diagnose Lupus. Instead, doctors use a combination of medical history, physical examination, and laboratory tests to make a diagnosis.

1. Medical history: Doctors will ask about your symptoms and whether you have any family history of autoimmune diseases.

2. Physical examination: A physical exam can help your doctor look for signs of Lupus, such as skin rashes or kidney damage.

3. Laboratory tests: Blood tests can help show if you have Lupus by looking for antibodies produced by the immune system to fight the disease.

4. Imaging studies: Imaging studies, such as X-rays or MRIs, can help show damage to organs caused by Lupus.

Causes of Lupus

There are many different causes of Lupus, and doctors are still trying to identify them. However, some of the most common include:

1. Autoimmune disorders: Lupus is an autoimmune disorder, which means the body’s immune system attacks healthy cells and tissues. This can be due to a genetic predisposition or something else entirely.

2. Hormonal imbalances: Lupus is often linked with hormonal imbalances, especially in women. Estrogen, in particular, seems to play a role in the development of Lupus.

3. Infections: Some infections have been linked to the development of Lupus. These include Epstein-Barr virus, hepatitis C virus, and parvovirus B19.

4. Medications: Some medications can trigger Lupus or make it worse. These include beta-blockers, lithium, hydralazine, and procainamide.

5. Radiation exposure: People exposed to large doses of radiation (such as from radiation therapy) are at increased risk for developing Lupus.

6. Sunlight: People with Lupus are often sensitive to sunlight, and exposure can trigger flare-ups or worsen them.

Treatment of Lupus

Lupus is a chronic autoimmune disease that can damage any body part. There is no known cure for Lupus, but treatments are available to help manage the symptoms and reduce the risk of flares. Some of the most common treatments for Lupus include:

1. Anti-inflammatory medications: These can help reduce inflammation caused by Lupus and prevent flares.

2. Corticosteroids: These powerful anti-inflammatory medications can be taken orally or injected directly into the affected joint or area of the body.

3. Immunosuppressive drugs: These drugs can help suppress the immune system and prevent it from attacking healthy tissues.

4. Biologic therapies: Newer drugs target specific parts of the immune system to help control inflammation.

If you have Lupus, you must work with your doctor to find a treatment plan that works for you. With proper treatment, many people with Lupus can live everyday, healthy lives.

How Lupus can be Prevented

There is no definitive answer to how Lupus can be prevented. Lupus is a chronic autoimmune disease with no known cure, and its exact causes are still not fully understood. However, specific measures can be taken to lower your risk of developing Lupus or to help manage the condition if you have already been diagnosed.

Some tips for preventing Lupus or managing the condition include:

  1. Get regular medical checkups and screenings, especially if you have a family history of Lupus or another autoimmune disease.
  2. Be aware of your triggers. If you know what environmental or emotional factors tend to trigger your lupus flares, try to avoid them as much as possible.
  3. Exercise regularly and eat a healthy diet. This will help boost your overall immunity and may help reduce your risk of developing Lupus or experiencing flares.
  4. Manage stress levels. Stress can trigger lupus flares, so finding healthy ways to manage stress (such as yoga, meditation, or therapy) can help prevent or manage the condition.
  5. Avoid sun exposure. People with Lupus are more sensitive to sunlight, so it’s essential to limit your disclosure and wear sunscreen outdoors.
  6. Be sure to take your medications as prescribed. If you have Lupus, taking any medications prescribed by your doctor to manage the condition and prevent flares is essential.
  7. Talk to your doctor about any vaccinations you may need. People with Lupus are at an increased risk for certain infections, so it’s essential to be up-to-date on all recommended vaccinations.

Complications of Lupus

Lupus is a chronic autoimmune disease that can affect any body part. The most common symptoms include fatigue, joint pain, muscle pain, rash, fever, and butterfly-shaped rashes on the face.

Complications of Lupus can vary from mild to life-threatening and can include:

1. Anemia: This is a common complication of Lupus and can be caused by either the disease itself or certain medications used to treat it. Anemia can cause fatigue, weakness, and shortness of breath.

2. Kidney problems: Lupus can cause inflammation of the kidneys (lupus nephritis), which can lead to kidney damage and kidney failure.

3. Neurological problems: Lupus can cause various neurological problems, including headaches, seizures, strokes, and psychosis.

4. Skin problems: Lupus can cause various skin problems, including rashes, ulcers, and photosensitivity (a reaction to sunlight).

5. Blood clots: Lupus can increase the risk of blood clots, leading to heart attacks, strokes, or pulmonary embolism (a blockage of an artery in the lungs).

Lupus is a chronic disease, and there is no cure. However, with early diagnosis and proper treatment, most people with Lupus can live everyday life.


Lupus is a chronic autoimmune disease that can be difficult to diagnose and treat. There is no one-size-fits-all approach to managing Lupus, but there are some treatments that can help alleviate symptoms and improve quality of life. If you think you may have Lupus, it’s essential to see a doctor so they can run the appropriate tests and start you on the road to treatment.
