The first trimester is the most critical time in your pregnancy. Although the
fetus at the end of three months is only about 4 inches long and weighs less
than 1 ounce, all of its functions have begun to form — major organs and nervous
system, heartbeat, arms, fingers, legs, toes, hair, and buds for future teeth.
This is not a time to skimp on food or count calories. You're not quite
eating for two people, but you do need extra nutrients for your growing fetus.
The general recommendation is to eat about 300 extra calories a day. You'll need
to gain 25 to 35 pounds during your pregnancy. This will allow you to nourish
your fetus and store nutrients for breast-feeding. Expect to gain at least 3 to
4 pounds during the first trimester.
For many women, the first trimester is also the period when you experience
the most profound changes. Although you may not appear pregnant, you'll
certainly feel all of the differences.
Common First Trimester Conditions
Morning Sickness and Nausea
The nausea — "morning sickness" — that
many women experience during the first trimester of pregnancy is the result of
hormonal changes. Morning sickness (which isn't necessarily limited to mornings)
may actually be a positive thing — though you may not feel particularly
grateful. Some scientists believe that morning sickness evolved as a natural way
of protecting women against foods that might contain dangerous microorganisms or
parasites, or foods whose chemical compositions might prove harmful to a
developing fetus, by expelling those foods. Also, increasing levels of the
hormone beta-hcg have been linked to nausea. Since high levels of beta-hcg tend
to protect against miscarriage, look on the bright side: Your morning sickness
may well be an early sign that your pregnancy is off to a good start. Morning
sickness usually disappears after the first trimester.
Mood Swings
Women are often surprised that they don't feel more
buoyant at the start of pregnancy — especially when it is a long-awaited result.
The stresses of the first trimester can produce many emotional ups and downs.
Although you may be delighted that you're pregnant, the hormonal adjustments
you're experiencing can make you feel anything but joyous. You may experience
mood swings, fatigue and insomnia, anxiety about your ability to experience a
successful pregnancy, and fear about what will happen.
Constipation
Constipation is a fact of life for most pregnant
women. Hormonal changes are largely responsible, signaling food to move more
slowly through your system as it nourishes your fetus.
Fatigue
Your entire system is fully engaged in creating a healthy
environment for your fetus — producing the placenta, a process that is completed
at the end of the third month, as well as providing sufficient nutrients. Every
organ is engaged in a vast reorganization. No wonder you're tired.
Food Aversions and Cravings
The food cravings and aversions that
many women experience during pregnancy are something of a mystery. While you may
crave what's good for you and be repelled by foods that are harmful, it doesn't
always work that way. Your best strategy is to eat what's right for you and try
to find replacements within your diet for the harmful foods you may crave.
Prenatal Supplements
Vitamins are very important to the developing
fetus. However, you should be aware that overdoing supplements can cause grave
problems in the baby, so consult your physician before taking
any
vitamins or supplements.
Virtually any of the commercial prenatal multivitamins will be effective. But
many are made with synthetic components rather than the preferred whole food
ingredients. Choose a blend of the B vitamins, along with antioxidants. Look for
quality, not quantity. Not all formulations release the specified amount of
nutrients on the label. When researchers at the University of Maryland tested
nine prescription prenatal vitamin tablets to see whether the folate contained
would dissolve, only three passed the muster. Two failed so miserably that they
released less than 25 percent of the folate specified on the label. That means
that if swallowed by someone, more than 75 percent of the folate in those pills
could possibly travel right through the body with very little chance of being
absorbed by the blood and transported to various tissues, including tissues
belonging to the fetus. If possible, use powder-in-capsule versus compacted
pills: Evidence suggests that dissolvability is a big problem with many
prenatals. Encapsulated ingredients do not need to dissolve.
Your daily prenatal vitamin/mineral supplement probably doesn't give you
enough calcium. Most of the daily prenatal formulas only contain about 200 to
300 milligrams of calcium — about 1,000 milligrams less than you and your baby
need every day. So check the label on your bottle or talk to your doctor. You'll
want to make sure that you are getting at least 1,200 milligrams of calcium
every day from natural food sources and supplements.
