Caffeine During Pregnancy: Effects on Baby
One of the first things most women think about once they see those two pink lines on our pregnancy tests is that beloved cup of morning coffee or tea; we worry about caffeine during pregnancy – effects on baby.
Our mothers and grandmothers will probably tell us that they drank the same amount of caffeine when expecting as they did when they were not pregnant and their children turned out fine. However, a lot more research has been done since their time and studies are showing that too much caffeine can cause some complications such as preterm labor and/or low birth weight.
How Caffeine Affects You
Caffeine is a central nervous system stimulant. It
increases your heart rate
increases blood pressure
is a diuretic – causes fluid loss
How Caffeine Affects Baby
Caffeine crosses the placenta
Your baby's metabolism cannot handle large amounts of caffeine
Lower birth wieght
Later studies reveal caffeine may alter the unborn baby's DNA
Possible link to childhood leukemia
So how much caffeine is too much caffeine? Doctors are telling their patients that a moderate amount of caffeine will not harm their babies. Even though caffeine does cross the placenta, anything less than 200 milligrams a day (a 12 ounce cup of strong coffee) will probably not do any harm.
Anything over 200 milligrams puts your baby at risk. A study by the American Journal of Obstetrics and Gynecology have also shown that women who drink more than 200 milligrams of caffeine a day during their first trimester have a slightly higher risk of a miscarriage.

Studies have also shown that women who had over 500 milligrams of caffeine a day had babies who had faster heart rates and faster breathing rates. These babies also spent more time awake in their first few days of life rather than peacefully sleeping after their long journey.
There are a number of other reasons why we women might want to cut back on the amount of caffeine we drink during pregnancy.
For starters, it has no nutritional value. If there is ever a time for us to be aware of our nutritional needs it is when we are pregnant.
Second, caffeine is a stimulant which will increase your heart rate and can cause insomnia and headaches which can put some stress on your growing little one.
Third, caffeine can cause heartburn. If you have been pregnant before you know that heartburn can be a burden to begin with, and caffeine just makes it worse.
Lastly it is a diuretic which means it can cause you to lose fluids which can put you at a risk of becoming dehydrated.
While it is not necessary for you to give up all caffeine through out the duration of your pregnancy, you should learn how to drink it in moderation or don't drink it at all. If you can not handle having only one cup of coffee a day, then you might be better off drinking no coffee at all.
Stick with caffeine free sodas and even decaf coffee. Remember though that decaf coffee still contains small traces of caffeine so make sure you take that into consideration. Caffeine during pregnancy – effects on baby – is safe in small amounts.
