Caffeine and pregnancy: What’s safe?

Caffeine actually has no nutritional value. We generally consume caffeine because it is a stimulant and it increases alertness. Caffeine can also increase our heart rates. It can cause insomnia and headaches. The unfortunate thing about all of this when you are pregnant is that caffeine crosses the placenta so it can potentially affect your baby the same way it affects you. This can put undue stress on your baby. Also, when you are pregnant you tend to be very tired and you need sleep. Anything that can potentially keep you from getting restful sleep is bad for you and bad for your baby.

Another concern with consuming caffeine during pregnancy is that it is a diuretic. This can cause you to become dehydrated because you are losing fluids, which can cause complications for you and for the baby.

While moderate amounts of caffeine have been deemed safe for the developing fetus, you may want to consider whether or not you want to continue drinking it at all during your pregnancy. Small amounts are okay and if you can stick with one small cup of coffee a day, you may be okay but do not drink more than that. You should stick with caffeine free drinks or decaf coffee instead. Or best of all, stop drinking caffeinated drinks and drink more clean, pure water instead.
