Complications

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.
• Brain and central nervous system. If your brain is affected by lupus, you may experience headaches, dizziness, behavior changes, vision problems, 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 a reduced number of healthy red blood cells (anemia) and an increased risk of bleeding or blood clotting. It can also cause inflammation of the blood vessels.
• Lungs. Having lupus increases your chances of developing an inflammation of the chest cavity lining, which can make breathing painful. Bleeding into lungs and pneumonia also are possible.
• Heart. Lupus can cause inflammation of your heart muscle, your arteries or heart membrane. 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 can weaken the immune system.
• Cancer. Having lupus appears to increase your risk of cancer; however, the risk is small.
• Bone tissue death. This occurs when the blood supply to a bone declines, often leading to tiny breaks in the bone and eventually to the bone's collapse.
• Pregnancy complications. Women with lupus have an increased risk of miscarriage. Lupus increases the risk of high blood pressure during pregnancy 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.
