Causes of miscarriage after the first trimester of pregnancy

Abortion is one of the most frequent complications of pregnancy. Most of them occur in the first 8 weeks of gestation , with few occurring after the third month. In all cases the symptoms are similar: vaginal bleeding greater than a period and menstrual pain. Faced with this situation, you should go to the obstetric emergency service of your referral hospital. The doctor will perform a vaginal examination and an ultrasound and will give you the definitive diagnosis.

Miscarriage in the second trimester

If you have an abortion, your obstetrician may need to perform a curettage. It is a surgical procedure that allows the uterus to be evacuated. Although this is an emotionally hard experience, keep in mind that most women with a miscarriage have a full term pregnancy in the next pregnancy.

When abortion takes place in the second trimester of pregnancy, it may be convenient to study the cause to prevent it from happening again. The reasons that miscarriage often occurs are:

  • Fetal congenital abnormalities, such as spina bifida or heart disease.
  • Uterine alterations (double uterus, incompetence of the cervix …).
  • Placental abnormalities, such as abnormal implantation or detachment of the placenta.
  • Maternal infectious diseases (toxoplasmosis, syphilis, rubella).
  • Chorioamnionitis or infection of the amniotic fluid.
  • Presence of antiphospholipid antibodies, which can cause placental infarcts.
  • Remember that most of the aforementioned conditions can be avoided with preconception treatment and monitoring by your obstetrician.
