Prenatal care is health care that a woman gets while pregnant. Going early and
regularly for prenatal care can help moms-to-be — and their babies — stay healthy.
Regular care lets doctors find and deal with any problems as soon as possible.
It's important to start prenatal care as early as possible — ideally, before a
woman even becomes pregnant.
How Can I Find Prenatal Care?
Pregnant women usually are cared for by:
obstetricians: doctors who specialize in pregnancy and childbirth
obstetricians/gynecologists (OB/GYNs): doctors who specialize in pregnancy and
childbirth, as well as women's health care
family practitioners: doctors who provide a range of services for patients of
all ages (sometimes, this includes obstetrical care) instead of specializing in one
certified nurse-midwife: an advanced practice nurse specializing
in women's health care needs, including prenatal care, labor and delivery, and postpartum
care for pregnancies without problems
Any of these care providers is a good choice if you're healthy and there's no reason
to expect problems with your pregnancy and delivery. However, nurse-midwives do need
to have a doctor available for the delivery in case a C-section
has to be done.
have another complicating factor that might put you in a high-risk category
Even if your pregnancy isn't high-risk, this may still be a good time to make a
change in health care providers if you're not comfortable with your current doctor.
Routine Visits and Testing
You should call to schedule your first checkup during the first 6 to 8 weeks of
your pregnancy, or when your period is 2 to 4 weeks late. Many health care providers
will not schedule the first visit before 8 weeks, unless there is a problem.
If you're healthy and have no complicating risk factors, you can expect to see
your health care provider:
every 4 weeks until the 28th week of pregnancy
then, every 2 weeks until 36 weeks
then, once a week until delivery
At each checkup, your weight and blood pressure are usually recorded. The size
and shape of your uterus may also be measured, starting at the 22nd week, to see whether
the fetus is growing and developing normally.
During one or more of your visits, you'll provide a small urine (pee) sample to
be tested for sugar (glucose) and protein.
Glucose screening usually takes place at 12 weeks for women who are at higher risk
diabetes. That includes women who:
previously had a baby that weighed more than 9 pounds (4.1 kilograms)
have a family history of diabetes
All other pregnant women are tested for diabetes at 24 to 28 weeks. They'll drink
a sugary liquid and have blood drawn after an hour for a blood glucose test. If the
blood sugar level is high, more testing can confirm whether it's gestational diabetes.
Some prenatal tests are screening tests that can only reveal the
possibility of a problem. Other prenatal tests are diagnostic tests
that can accurately find whether a fetus has a specific problem. A screening test
sometimes is followed by a diagnostic test. These can include blood tests, amniocentesis,
CVS, and ultrasound
Common Pregnancy Concerns
Some women worry about medical conditions they already have, such as diabetes,
and how they could affect a pregnancy. It's important to talk with your doctor, who
may recommend a change in medicines or treatments that could ease your concerns.
Other conditions that can come with pregnancy include:
gestational diabetes: Some pregnant women develop this condition,
usually after the first trimester. The placenta provides the fetus with nutrients
and oxygen, and also makes hormones that change the way
works. Insulin helps the body store the sugar in food, which is later
converted to energy. In gestational diabetes, a problem with insulin leads to a high
blood sugar level.
preeclampsia (also called toxemia of pregnancy): This condition
can happen after the sixth month, causing high blood pressure, edema (fluid buildup
in body tissues that causes swelling of the hands, feet, or face), and protein in
Rh-negative mother/Rh-positive fetus (also called Rh
incompatibility): Most people have Rh factor in their red blood cells
(they're Rh positive). Those who don't are Rh negative. A simple blood test can determine
your Rh factor. If your baby is Rh positive and you're Rh negative, problems can happen
when the baby's blood cells enter your bloodstream. Your body may react by making
antibodies that can pass into the fetus' bloodstream and destroy red blood cells.
These conditions are serious but manageable. So it's important to learn about them
and discuss them with your health care provider.
Diet and Weight Gain
Many pregnant women wonder about weight gain. Generally, women of normal weight
should gain about 25–35 pounds during pregnancy. For women who start their pregnancy
overweight, total weight gain should be closer to 15–25 pounds. Those who are underweight
should gain 28–40 pounds.
Controlling weight gain is harder later in a pregnancy, so try to avoid gaining
a lot of weight during the first few months. However, not gaining enough weight can
cause problems too, such as poor fetal growth and premature
Pregnancy is not a good time to start a diet, but it is a great
time to enjoy healthier
foods. Doctors recommend that women add about 300 calories to their daily intake
to help nourish the developing baby. Protein should supply most of these calories,
but your diet also should include plenty of fresh fruits, grains, and vegetables.
Your health care provider may prescribe a prenatal vitamin to make sure you get
enough iron, calcium, and folic
acid. It's also a good time to get regular, low-impact exercise.
What Else Should I Know?
For your baby's sake and yours, it's important to take especially good care of
yourself during your pregnancy. Follow these basics:
Over-the-counter medicines are generally considered off-limits because of their
potential effects on the fetus. Most doctors recommend not taking any OTC medicines
if possible, but might offer a list of those they think are safe. Be sure to discuss
any questions about medicines (including natural remedies, supplements, and vitamins)
with your doctor.
When you're pregnant, it's also important to avoid foodborne illnesses, such as
listeriosis and toxoplasmosis, which
can be life-threatening to an unborn baby and may cause birth defects or miscarriage.
Foods to steer clear of include:
soft, unpasteurized cheeses (often advertised as "fresh") such as feta,
goat, Brie, Camembert, and blue cheese
unpasteurized milk, juices, and apple cider
raw eggs or foods containing raw eggs, including mousse and tiramisu
raw or undercooked meats, fish, or shellfish
processed meats such as hot dogs and deli meats (these should be well cooked)
Also avoid eating shark, swordfish, king mackerel, marlin, orange roughy, tuna
steak (bigeye or ahi),and tilefish. Fish and shellfish can be an extremely healthy
part of your pregnancy diet because they contain beneficial omega-3 fatty acids and
are high in protein and low in saturated fat. But these types of fish may contain
high levels of mercury, which can damage the developing brain of a fetus.
Your doctor may recommend a couple of vaccines during pregnancy. The flu
shot can curb flu-related problems for expectant moms, who are at higher
risk of problems from the illness. The flu shot is recommended by the Centers for
Disease Control and Prevention (CDC) during any stage of pregnancy. Pregnant women
should only get the shot, and not the nasal spray (or mist) form.
The Tdap vaccine (against tetanus,
diphtheria, and pertussis) is now
recommended for all pregnant women in the second half of each pregnancy,
regardless of whether they've gotten it before or when it was last given. This is
because there's been a rise in pertussis (whooping cough) infections, which can be
fatal in newborns who have not yet had their routine vaccinations.
Physical Changes of Pregnancy
Pregnancy can cause a number of uncomfortable (but not necessarily serious) changes,
nausea and vomiting, especially early in the pregnancy
varicose veins in the legs and the area around the vaginal opening
If you have any of these changes, you're not alone! Talk to your doctor about ways
to ease your discomfort.
Talking to Your Health Care Provider
When your body is going through physical changes that may be completely new to
you, it isn't always easy to talk to your health care provider. Maybe you're wondering
whether you can have sex
or what to do about hemorrhoids or constipation, or maybe you're feeling feeling worried
about the delivery.
You might feel embarrassed to ask these or other questions, but it's important
to do so — and remember, your health care provider has heard them all before. Keep
a running list of questions, and take it with you to each visit.
