Lupus erythematosus refers to systemic lupus erythematosus (SLE), which is an immune disease. If the disease is stable, it is possible to have a child, but if the disease is unstable it may lead to pregnancy failure and is not recommended. SLE is an immune disease. When the disease is well controlled, the autoantibodies in the body will decrease and there is a chance to prepare for pregnancy and complete the whole pregnancy process, so it is possible to have children. If the patient’s condition is unstable and the level of autoantibodies in the body is high, it is easy to lead to immune infertility, and even after pregnancy, it is easy to irritate the fetus and prevent it from growing normally, so it is not recommended to have children. It is recommended that SLE should be actively treated to stabilize the condition. Before preparing for pregnancy, it is recommended to consult a doctor in time, improve the examination and prepare for pregnancy under the doctor’s guidance to improve the success rate of pregnancy.
