Why Some Women Experience More Than One Miscarriage

0 68

Around 1% of women will experience repeated miscarriages. Most of these miscarriages occur randomly, caused by abnormal chromosomes in the fetus. No medical condition precedes it; it happens purely by chance. And as the woman ages, the likelihood of this random miscarriage can increase.

If a woman miscarries more than once, despite being relatively young, the cause often involves chromosomes as well. But sometimes, it’s a more serious condition that makes the fetus incompatible with the mother’s placenta. Thankfully, today’s prenatal examinations can detect risks of a miscarriage, allowing couples or single mothers to plan what to do with the pregnancy. If you got pregnant ahead of planning, don’t be ashamed to consider a safe medical abortion if that’s the only way to save your life and spare your baby from a difficult life.

Despite being on top of their prenatal needs, some women may still experience repeated miscarriages. These are the causes of repeated miscarriages and the ways to prevent them, if possible:

  1. Translocation

In most miscarriages, genetic abnormalities are the cause. It is when the embryo receives an abnormal number of chromosomes during fertilization. But if it occurs repeatedly, one partner may have a chromosome in which a piece is transferred to another chromosome. This is called translocation.

Translocations can be completely harmless. Many people actually experience them without being aware. However, even if it causes no problems on the couple’s bodies, it risks the fetus’ life. When a piece of a chromosome breaks off and attaches itself to another chromosome, the egg or sperm cell may end up with extra genetic material or missing genetic material. Depending on which chromosome was affected, the woman’s body will detect the abnormal chromosome and end the pregnancy.

To find out if you had dealt with translocation, a test called karyotype is performed. It requires you and the father’s blood samples. The test would determine which one of you was the carrier of translocation. Unfortunately, if translocation were confirmed, there would be no cure for it. But thankfully, the odds often gravitate toward a healthy pregnancy. But if translocation and miscarriage have already occurred multiple times, the woman may already have a scar tissue buildup. This may warrant high-tech means to carry a pregnancy to full-term.

  1. Ectopic Pregnancy

An ectopic pregnancy is when the fetus develops not in the uterus, but in the fallopian tube, abdominal cavity, or cervix instead. The cause isn’t always clear, but a number of conditions have been linked to it.

If you’ve had inflammation or scarring in your fallopian tube from a previous medical condition, infection, or surgery, your risks for ectopic pregnancy may increase. Hormonal factors may also contribute, and so may genetic abnormalities, birth defects, and medical conditions that affect the shape of the reproductive organs.

Your maternal age could play a role, too. Getting pregnant when you’re older than 35 can increase your risks. Conception aided by drugs, smoking, endometriosis, and a history of STDs is also associated with ectopic pregnancy.

The only treatment for an ectopic pregnancy is a surgical abortion. The embryo must be removed as early as possible because ectopic pregnancy is unsafe for the mother. A doctor will also prescribe medications to prevent the ectopic mass from bursting.

  1. Placental Insufficiency

Sometimes, a woman’s placenta isn’t compatible with the embryo. This would not allow the baby to receive adequate nourishment from the mother. If not a miscarriage, placental insufficiency can lead to low birth weight, premature birth, or birth defects.

The common health conditions linked to placental insufficiency include diabetes, hypertension, anemia, and blood clotting disorders. Bad habits, such as smoking and drug abuse, are risk factors as well. If a mother takes blood thinners to treat an illness, that can also affect their placenta.

For the mother, placental insufficiency can lead to more health issues, especially if diabetes or hypertension has caused it. They may experience preeclampsia, placental abruption, or preterm labor and delivery as a result. For the baby, not receiving enough nutrition can decrease their oxygen supply in the womb and affect their cognitive abilities at birth. They’d be basically born with poor health.

Placental insufficiency is fortunately treatable, but it’ll always result in a high-risk pregnancy. You need to keep a daily record of the baby’s movement to monitor its development more closely.


If you suffer from the health issues associated with the causes of repeated miscarriages, you may need to wait longer before conceiving. While waiting, take measures to improve your overall health. A lifestyle change will significantly help. Consult your doctor regularly, too, so that you and your partner can determine your reproductive compatibility.
