Question and answer
Inflammation caused by lupus can affect many areas of your body, including your:
- Kidneys. Lupus can cause serious kidney damage, and kidney failure is one of the leading causes of death among people with lupus. Signs and symptoms of kidney problems may include generalized itching, chest pain, nausea, vomiting and leg swelling (edema).
- Brain and central nervous system. If your brain is affected by lupus, you may experience headaches, dizziness, behavior changes, hallucinations, and even strokes or seizures. Many people with lupus experience memory problems and may have difficulty expressing their thoughts.
- Blood and blood vessels. Lupus may lead to blood problems, including anemia and increased risk of bleeding or blood clotting. It can also cause inflammation of the blood vessels (vasculitis).
- Lungs. Having lupus increases your chances of developing an inflammation of the chest cavity lining (pleurisy), which can make breathing painful. You may also be more susceptible to pneumonia.
- Heart. Lupus can cause inflammation of your heart muscle, your arteries or heart membrane (pericarditis). The risk of cardiovascular disease and heart attacks increases greatly as well.
Other types of complications
Having lupus also increases your risk of:
- Infection. People with lupus are more vulnerable to infection because both the disease and its treatments weaken the immune system. Infections that most commonly affect people with lupus include urinary tract infections, respiratory infections, yeast infections, salmonella, herpes and shingles.
- Cancer. Having lupus appears to increase your risk of cancer.
- Bone tissue death (avascular necrosis). This occurs when the blood supply to a bone diminishes, often leading to tiny breaks in the bone and eventually to the bone's collapse. The hip joint is most commonly affected.
- Pregnancy complications. Women with lupus have an increased risk of miscarriage. Lupus increases the risk of high blood pressure during pregnancy (preeclampsia) and preterm birth. To reduce the risk of these complications, doctors often recommend delaying pregnancy until your disease has been under control for at least six months.
