Mayo Clinic: Six months ago, after becoming pregnant for the
first time, I had a miscarriage at 12 weeks. My husband and I
want to become pregnant again, but weíre worried about
another miscarriage. Are there things I can do to prevent it
this time? Iím 27 years old, and I donít have any health
Having a miscarriage can be shocking, stressful and sad. Itís
understandable that you want to do everything you can to avoid
going through it again. Although there are some steps you may
be able to take to lower your risk of another miscarriage, in
most cases, a miscarriage isnít related to anything a
pregnant woman did or did not do. The majority of miscarriages
are due to chromosomal abnormalities that happen for no clear
reason. Many women who have a miscarriage go on to have normal
pregnancies and deliver healthy babies.
general, a miscarriage is defined as the loss of a pregnancy
before 20 weeks gestation. Because it is not a topic that
receives much attention, miscarriage tends to be more common
than people might think. Doctors estimate that up to 25
percent of all recognized pregnancies end in miscarriage.
miscarriages happen because the fetus isnít developing
normally. Problems with the babyís genes or chromosomes are
usually the result of errors that occur by chance as the
embryo divides and grows. They typically arenít due to an
inherited disorder, and usually arenít caused by a motherís
behavior or health.
said, there are a few risk factors that can raise the chances
of having a miscarriage. Among the most significant is
advanced maternal age. This one doesnít apply to you right
now, and it wonít for some time. Women older than 35 have a
higher risk of miscarriage than do younger women. At 35, the
risk of miscarriage is about 20 percent risk. At 40, it goes
up to about 40 percent. At 45, itís about 80 percent.
risk factor that doesnít sound like it fits your situation
is having certain medical conditions. Some disorders that may
raise the risk of a miscarriage include uncontrolled diabetes,
high blood pressure, thyroid disease, infections, hormonal
problems and problems with the uterus or cervix.
comes to lifestyle choices you can control, it is important to
avoid smoking, drinking alcohol or using illegal drugs when
you are pregnant. Not only do these activities raise your risk
for a miscarriage, they endanger the health of your baby
throughout pregnancy. If you are on prescription medication,
ask your doctor if itís safe to continue taking that
medication during pregnancy.
at a healthy weight before you become pregnant and throughout
your pregnancy may also help ensure your babyís health.
Being underweight or overweight appears to be linked to an
increased risk of miscarriage, as well as other health
concerns during pregnancy. For example, women who are
significantly overweight are more likely to develop
the following activities cause miscarriage: lifting,
straining, having sex or exercising.
have questions or concerns about becoming pregnant again, talk
to your health care provider. He or she can review your health
and family history, talk with you about risk factors and
discuss any preconception care that could be helpful.
go forward, please keep in mind that, in almost all cases,
miscarriages are beyond a motherís control. If you become
pregnant again, unless an underlying medical condition is
identified that needs special care, you shouldnít need to do
anything differently. Get regular prenatal care and focus on
taking care of yourself and your baby.
