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.
