What causes recurrent pregnancy loss?

50-80% of recurrent miscarriages in the first trimester are caused by genetic or chromosomal abnormalities of the embryo. A repeated pregnancy failure can result from the fetus carrying abnormalities repeatedly.

Genetic Causes

Antibodies produced by mothers can cause clotting of blood vessels during pregnancy, resulting in specific types of autoimmune diseases. Due to this, the fetus is deprived of essential growth nutrients. As a result, the baby normally dies in utero. This also causes a miscarriage.

Autoimmune Diseases

Uterine structural problems lead to about 15% of miscarriages. The abnormalities can be congenital, like a double uterus or a septate uterus, or develop at birth. A septate uterus is one of the most common causes of miscarriage.

Uterine anomalies

Several medical conditions can increase miscarriage risk, including thyroid disease, diabetes, and immune system or blood clotting disorders.

Medical condition

When endocrine issues such as diabetes, thyroid, pituitary glands, or polycystic ovarian syndrome are present, recurrent miscarriages are more likely.

Endocrine issues

There are environmental factors that can increase the chances of pregnancy loss, such as exposure to toxic and chemical substances. Alcohol, caffeine, and smoking are also lifestyle factors that can cause recurrent pregnancy loss. Obesity or being overweight can also be reasons for miscarriages.
