Caffeine and Pregnancy: What’s Safe?

By Jordan Coauette, MD May 05, 2017

Whether it’s white mochas, chai tea lattes or Diet Cokes, many people have a caffeinated beverage of choice. But when you become pregnant, you might want to think about kissing those delicious vices goodbye.

Caffeine is a drug found in many foods, drinks and even some medications. It is a stimulant, which means it can keep you awake and increases your blood pressure and heart rate. It is also a diuretic and can lead to dehydration.

None of these things are recommended during pregnancy. Plus, when you are pregnant, what you ingest, your baby also ingests. So when you eat and drink things containing caffeine, it passes through the placenta and reaches your baby. And while caffeine might not affect you very much, your baby’s metabolism isn’t as mature and cannot metabolize it as well.

According to The March of Dimes, women who are pregnant or trying to get pregnant should have no more than 200 mg of caffeine per day. This is the amount of caffeine in about a 12-ounce cup of coffee. While there is no conclusive evidence between the correlation of caffeine and miscarriages, it is better to play it safe with caffeine intake.
