Caffeine In Pregnancy

It’s common knowledge that pregnant women and those trying to conceive should limit their consumption of caffeine. And though there’s still no consensus on just how much caffeine is safe during pregnancy, there’s general agreement that it’s better to limit the daily consumption to less than 200 mg per day.

Caffeine In Pregnancy

Too much caffeine during pregnancy increases your blood pressure and heart rate, both of which are not recommended when you’re pregnant. It also increases the frequency of urination, which can lead to dehydration and harm your baby.

Caffeine crosses the placenta to your baby. Since your baby’s metabolism is still developing,  it cannot fully metabolize the caffeine. Caffeine can also cause changes in your baby’s normal sleep and movement patterns in the later stages of pregnancy. This is true for newborn babies as well, especially for the first few months, which means you should remember to limit your consumption of caffeine if you’re breastfeeding.

Numerous studies on animals have shown that caffeine can cause reduced fertility, birth defects, preterm delivery, increase the risk of a slight reduction in the baby’s birth weight and other problems. And although there have not been any conclusive studies done on humans, better not take any risks.

Caffeine can be found in other foods and beverages besides coffee. It also shows up in soft drinks, energy drinks, desserts such as chocolate and coffee ice cream, and even in common over-the-counter drugs, like some headache, cold (Dimetapp Cold and Fever, Actifed Cold and Sinus, Sudafed Nasal Decongestant and more), and allergy remedies. The Food and Drug Administration (FDA) requires that label on medicine lists the amount of caffeine in the medicine, so read labels and instructions carefully and consult your physician when in doubt. Most labels require you do that anyway.

One thing’s for sure: Considering the effects of caffeine in pregnancy, you’ll feel better if you cut down your consumption of tea and coffee. Caffeine may increase your heart rate, cause insomnia and even contribute to heartburn by stimulating the secretion of stomach acid. As your pregnancy progresses, you may feel these symptoms more acutely. That’s because your body’s ability to break down caffeine slows, so you end up with a progressively higher level of it in your bloodstream. During the second trimester, it takes almost twice as long to clear caffeine from your body as when you’re not pregnant. During the third trimester, it takes nearly three times as long. Bear that in mind.

Finally, there’s one more reason to cut back on coffee and tea, even if you drink them decaffeinated. These beverages contain compounds called phenols. Phenols make it harder for your body to absorb iron. This is particularly important because many pregnant women are already low on iron (It’s high chance that your physician has already prescribed you an iron supplement). If you must have your cup of coffee or tea, drink it between meals so it’ll have less of an effect on your iron absorption.

As you you can see, there is no need to abandon your morning cup of joy. However, there is much you can do to limit your caffeine intake during pregnancy. Try switching to decaf, using a smaller amount of ground coffee or tea leaves or brewing for a shorter time. As caffeine increases the frequency of urination, drink more water and freshly squeezed fruit and vegetable juice. Not only they taste great, but they also contain much-needed vitamins.

    A friend told me of a woman who kept drinking strong coffee through her pregnancy, and her baby is very restive, keepss crying and has troubles sleeping. Is this likely?

  • ToGo

    So, I guess decaf is safe, right?

    • Your Pregnancy

      Yes. That doesn’t mean you should drink nothing but decaffeinated coffee, mind. A cup or two a day will do.

  • Eilin

    I’d think my body consumes the caffeine before my baby did, right? so how much caffeine does my baby take in after my body does? I drink about one or two coffees a week.

    • Your Pregnancy

      It’s difficult to say just how much caffeine your baby takes. It’s enough to know that its body doesn’t fully metabolize the caffeine, since its metabolism is still developing. But two coffees a week is more than safe. I’d say you have nothing to worry about.

    OMG, there’s caffeine in green tea as well?!
