What autoimmune disease causes miscarriages
What autoimmune disease causes miscarriages Autoimmune diseases are conditions in which the body’s immune system mistakenly attacks its own tissues, leading to a variety of health issues. Among women of reproductive age, certain autoimmune disorders have been linked to an increased risk of miscarriage, posing significant challenges for those trying to conceive. Understanding the connection between autoimmune diseases and miscarriages is crucial for early diagnosis, proper management, and improving pregnancy outcomes.
One of the most prominent autoimmune diseases associated with recurrent pregnancy loss is antiphospholipid syndrome (APS). APS is characterized by the presence of abnormal antibodies—antiphospholipid antibodies—that increase the tendency for blood clot formation. These clots can develop in placental blood vessels, impairing blood flow to the developing fetus and resulting in miscarriage, often in the first trimester. Women with APS may experience multiple pregnancy losses, and the condition can occur either as a primary disorder or in conjunction with other autoimmune diseases like lupus.
Systemic lupus erythematosus (SLE), commonly known as lupus, is another autoimmune disease that can complicate pregnancy. Lupus causes widespread inflammation affecting various organs and tissues, including the skin, joints, kidneys, and the vascular system. Pregnancies in women with lupus are considered high risk due to the potential for flares, preeclampsia, and placental insufficiency. These complications can lead to miscarriage, preterm birth, or fetal growth restriction. The presence of specific lupus-related antibodies, such as anti-Ro/SSA and anti-La/SSB, can also elevate the risk of pregnancy loss.

Other autoimmune conditions like rheumatoid arthritis and autoimmune thyroid diseases (such as Hashimoto’s thyroiditis and Graves’ disease) have been associated with increased miscarriage risk, although their impact is generally less direct compared to APS and lupus. For instance, uncontrolled thyroid disease can affect hormone balance essential for pregnancy maintenance, increasing the likelihood of miscarriage.
Diagnosis of autoimmune-related pregnancy loss involves blood tests to detect specific autoantibodies, alongside clinical history. Management typically includes immunosuppressive therapies, anticoagulants such as low-dose aspirin or heparin, and close monitoring throughout pregnancy. For women with antiphospholipid syndrome, the combination of aspirin and heparin has been shown to significantly improve pregnancy outcomes.
Early recognition and treatment of autoimmune conditions can dramatically reduce the risk of miscarriage. Women with known autoimmune diseases should consult healthcare providers experienced in high-risk pregnancies before conception. Multidisciplinary care involving rheumatologists, obstetricians, and hematologists can optimize both maternal health and fetal development.
In conclusion, autoimmune diseases like antiphospholipid syndrome and lupus are significant contributors to pregnancy loss. Awareness, timely diagnosis, and appropriate management are vital to improve the chances of a successful pregnancy for women affected by these conditions.
