It’s Not Your Fault: 8 Reasons Why Miscarriage Might Happen

1. Genetic Abnormalities:One of the common reasons for early miscarriage is a genetic or chromosomal malformation with the embryo. For example, in many cases, the fetus has an extra or missing chromosome.

2. Hormonal Abnormalities:definite hormonal imbalances — for example, low progesterone levels (or what’s called luteal phase deficiency) — may cause miscarriages.Your doctor can test for this, and through treatment, raise your chance of a successful pregnancy. That might include lifestyle changes (for example, too much exercise can cause disturbances of hormone production), progesterone supplementation, and use of fertility medications.

3. Uterine Abnormalities:Some women are born with a septum, which is a band of tissue inside the uterus that makes the uterus too compact. If you have repeated miscarriages, your doctor can test for this, and surgery can help to correct it.Other women can develop fibroids in the uterine cavity. Fibroids are benign tumors and they’re very common — as many as three out of four women may have them at some point. Fibroids can cause difficulty with an embryo attaching to the uterine wall, which can cause a miscarriage.

4. Untreated Medical Conditions:Before trying for a baby, it’s helpful to have a full medical evaluation by a physician. That’s because the risk of miscarriage can increase with untreated medical conditions like diabetes or thyroid disease.

5. Infections:There’s also a higher risk of miscarriage for women with infections like measles, cytomegalovirus, listeria, rubella, mumps, gonorrhea, or parvovirus.

6. Antiphospholipid Syndrome:An elevation in antiphospholipid antibodies can lead to blood clots and interfere with implantation and growth of an embryo. Your doctor can test for this, and treatment with blood thinners can often improve pregnancy outcomes in this case.

7. Lifestyle Choices:Of course, there are certain factors to keep in mind when trying for a baby. Tobacco and alcohol can up the risk of miscarriage, as can obesity. Some studies have also found a link between high caffeine consumption and increased risk of miscarriage.The good news is that these factors are often the easiest to address and rectify. Quitting smoking, dropping weight and steering clear of alcohol and tobacco can go a long way in improving the chance of a successful pregnancy.

8. Unexplained Factors:Unfortunately, for about half of all miscarriages, there’s no diagnosable cause. But the American Society of Reproductive Medicine suggests that many of these are likely due to genetic abnormalities.
