Habitual miscarriage (repeated miscarriage ) is diagnosed when three or more consecutive spontaneous miscarriage occur with the same partner, before the 20th week of pregnancy.

Miscarriages are not uncommon and clinical trials show that between 10-20% of all pregnancies result in miscarriage. It is believed that the true number is much higher, because many happen in the very early stages of pregnancy, when women are not even aware that they are pregnant.

Causes of recurrent pregnancy losses

The cause can be genetic, anatomical, immunological and hormonal (dysfunction of the thyroid gland).

Large studies have shown that infection and certain disorders of blood coagulation (thrombophilia) are not risk factors for habitual miscarriages.

What are the symptoms of spontaneous miscarriages?

Most miscarriages occur before the 12th week of pregnancy. Symptoms of miscarriage are vaginal bleeding, pain and cramps in the lower abdomen, as well as pain in the lower back.

The causes of repeated miscarriages are diagnosed by laboratory and genetic analyses, ultrasound examination (3D), MRI and hysteroscopy (by inserting a camera into the uterine cavity).

If the cause is identified, it is treated with medications and surgery (hysteroscopic surgery).

In a large number of cases, the cause is not discovered.
