Many women decide to have children
later in life, but pregnancy after 40 can pose additional risks and
complications to the mother and baby. Although a healthy pregnancy after 40 is
very likely, preparing yourself before you become pregnant can help you get
your body in optimum condition for a successful pregnancy. Women who want to
conceive after 40 also need to prepare for a higher risk of complications
during the birth, difficulty conceiving, and the greater likelihood that their
babies may experience Down syndrome or other chromosomal birth defects.
·
Schedule a
physical or pre-conception consultation with your primary caregiver or
gynecologist.
As people age, the
likelihood of suffering from common health conditions such as high blood
pressure and diabetes increases, and older women may also be more likely to
have conditions that impair fertility such as polycystic ovary syndrome or
endometriosis. A doctor can help you identify health problems.
·
Make sure
you tell your doctor you want to conceive. Ask for a realistic time frame in
which you can resolve or manage any existing health issues before trying to
conceive.
·
Discuss
whether you will be able to continue using any medications you are currently
taking while you try to conceive and while pregnant or breastfeeding. Ask your
doctor about alternate therapies or medications safe during pregnancy, and be
realistic about whether you can manage your health problems without medication
if that is the only option for a safe pregnancy.
·
Evaluate
with your doctor which health problems are most important for you to address
before pregnancy. Because fertility begins to decline after 35 years in most
women, many women preparing for pregnancy after 40 are balancing the need to
manage health problems with a rapidly diminishing fertile period.
·
Get any
immunizations your doctor recommends. Your doctor may perform blood work to
check for immunity to diseases such as rubella and chickenpox--wait 1 month to
try conceiving after you get a vaccine.
·
Manage any
existing health problems before conceiving.
Health issues that
have a mild effect on your everyday life currently may become major
complications once you are pregnant. For example, unmanaged diabetes can
greatly increase your risk for miscarriage and moderate high blood pressure can
quickly worsen.
·
Get
treatment for sexually transmitted infections and diseases immediately as these
can lead to infertility.
·
Work on
getting to a healthy weight. Overweight and underweight can both cause
significant problems while pregnant or trying to conceive. For example, women
with unhealthily low weights can have anovulatory cycles making it impossible
for them to conceive.
·
Improve your nutrition.
Good nutrition is especially important during the preconception period
as healthy levels of folic acid and other vitamins can help prevent certain
birth defects.
·
Although vitamin supplements are
available, try to increase your intake of foods naturally containing folate
including citrus fruit, legumes, and dark leafy greens. Folate can help prevent anemia and
birth defects.
·
Eat whole grain, complex
carbohydrates and cut down on the amount of refined carbohydrates you consume.
·
Get protein from lean meats and
fatty fish rich in omega-3 such as salmon, eggs, and low-fat dairy.
·
Reduce the amount of sugar you eat.
Begin
exercising or increase your activity level.
Exercise can help you maintain a healthy weight and may allow you to
have a more comfortable pregnancy and labor.
·
Include both aerobic and resistance
training in your exercise program.
·
Stop smoking and avoid secondhand
smoke.
Smoking can lower fertility, even leading to early menopause, and causes
a number of complications during pregnancy such as low birth weight and
increased rates of respiratory distress in infants.
·
Talk to your partner about quitting-secondhand
smoke is also harmful, and men who smoke have lower fertility than their
non-smoking counterparts.
·
Consider the risk of chromosomal
birth defects.
Although many older women have healthy pregnancies, the reality is that
the rate of chromosomal birth defects is much higher in infants born to women
over 40. One out of 100 women who are 40 years old will have a baby with Down
syndrome, and the risk increases with age, rising to 1 in 30 women at age 45.
·
Discuss the possibility of birth
defects with your partner and/or family. Decide whether you want to take the
risk, and plan out how you would cope with a diagnosis.
·
Research the additional diagnostic
tests available during pregnancy. You may be interested in amniocentesis or
chronic villus sampling (CVS), but both tests do carry a slight risk for
miscarriage.
·
Take into account the higher rate of pregnancy loss.
The estimated miscarriage rate for
women between 40 and 45 is 35 percent and this rises to over 50 percent for
women over 45. Older women also experience a rate of stillbirth 2 to 3 times
higher than that for women in their 20s. Stillbirth is death of the fetus after
20 weeks. Evaluate whether you feel emotionally prepared to experience
pregnancy loss, possibly multiple times, while trying to have a baby.
·
Make an appointment with a genetic
counselor.
If you are especially concerned with the risk for birth defects or other
health problems for the infant, a genetic counselor can help you assess the
likelihood of problems.
·
Gather together information on
maternal and paternal family members including any illnesses, health conditions
or reproductive issues. The counselor will review your family history as part
of the assessment.
·
Follow up with your doctor while trying to conceive.
Since the probability of fertility
problems is so much higher for women over 40, you should consult a doctor if
you do not conceive within 6 months of trying to conceive. Waiting longer may
diminish your chances of conceiving, as your fertility may be declining and alternate
treatments also become less successful as you age.
