Pregnancy – “Rules of the Game”

Congratulations, you’re pregnant! Now for the barrage of all the things you NEED to do or NOT do while pregnant. Sound familiar? In our current society, it’s commonplace that when a woman announces she is expecting for a lot of advice to follow – and I mean A LOT! Some of these tips are sought after, such as health information from an obstetrician, while other suggestions might not be solicited, such as from well-meaning friends and family and even strangers. With all the guidance and lack of reasoning or information to back it, this can be a very stressful time, especially for a first-time expectant mother. This article is an attempt to explain the WHY behind some of the recommendations your obstetrician might suggest throughout your pregnancy.

Why is it recommended to take a prenatal vitamin while pregnant?

While eating a balanced diet that’s rich in vitamins and minerals is certainly the best way to keep healthy in pregnancy, a healthy diet alone may not suffice. Compared to a standard daily multivitamin, prenatal vitamins contain higher levels of certain nutrients that a growing baby requires – such as folic acid, calcium, and iron. These vitamins assist with proper development and studies suggest they help reduce the risk of birth defects. DHA and EPA are omega-3 fats that are important in your baby’s brain development. It’s true that too much of a good thing can be a bad thing though, so it’s important not to take more than the recommended amount of your daily vitamin to prevent harmful effects on your body.


Why should I quit smoking while pregnant?

Smoking while pregnant can lead to lower birth weight, increased risk of placental abruption (placenta detaching from the uterus too early), increased risk of preterm delivery, and greater risk for learning disabilities. Children born to women who smoke are also more likely to try smoking at a young age and become smokers themselves. It’s best to quit before you conceive, but if not, then as early in pregnancy as possible.

Do I have to forego the gym and “take it easy” now that I am pregnant?

Is it safe to get the flu vaccine while pregnant?

By all means, pregnant woman who do not have any contraindications to receiving the flu vaccine, SHOULD get the vaccine in pregnancy.

And there you have it! Hopefully this helps answer some of the whys behind the sometimes odd-sounding recommendations of pregnancy. Don’t be afraid to ask your obstetrics provider for the reasoning behind their suggestions and perhaps other advice you may receive while pregnant. It’s always best to be informed and part of the decision making when following the certain “rules of the game”. Overall, this will lead to a healthier, happier, less stressful pregnancy.
