Lupus is a long-term (chronic) disease. It causes inflammation in the body. It mainly affects the joints, skin, and muscles. Lupus can affect almost any part of the body. Other common sites affected by lupus include the kidneys, blood cells, lungs, brain, nerves, intestines, eyes, mouth, and heart. Lupus is an autoimmune disease. This means that immune cells in the body attack normal body cells. The cause of this is not known.
Common symptoms include:
- A butterfly-shaped rash across the bridge of the nose and cheeks, or a disk-shaped rash on the face, neck, or chest.
- Sun sensitivity. (A short time in the sun may lead to severe sunburn or rash.)
- Stiff, painful, or swollen joints (arthritis) and muscle pain.
- Extreme tiredness (fatigue) or depression.
- A fever.
- Chest pain when breathing deeply.
- Mouth sores.
- Anemia.
- Hair loss.
But since lupus can affect many different organs in the body, other symptoms may be seen. These include:
- Swollen glands.
- Belly (abdominal) pain.
- Heart valve damage due to inflammation. This can lead to scarring.
- Inflammation of the lining around the heart muscle, called pericarditis.
- Inflammation of the heart muscle itself, called myocarditis.
- Inflammation of blood vessels, called vasculitis.
Your doctor may prescribe medicines, such as oral steroids, or medicines to suppress the immune system. Some people benefit from other medicines, such as antimalarials. People with lupus are more likely to have heart disease. So it's important to manage other risk factors for heart disease. These include high blood pressure, obesity, smoking, and unhealthy cholesterol.
There's no cure for lupus. But with correct treatment and management, most people with lupus can lead normal, active lives.
