Many factors affect the development of a fetus into a healthy child, some which are beyond your control and others that are within your control. Here are ten of the most common pregnancy risk factors that can be controlled or influenced:

1. Smoking - Smoking is not only bad for you, but bad for your baby as well. Smoking during pregnancy reduces the amount of oxygen that the baby receives and increases the risk of miscarriage, bleeding, and morning sickness. Chemicals inhaled while smoking may lead to other health problems with the baby. Reduced birth weight, premature birth, increased risk of SIDS, and stillbirth are other possible consequences.

Caffeine has been shown to affect fetal heart rates and awake time (fetuses grow when sleeping). Decaffeinated coffee can also be harmful since producers often add additional chemicals to remove the caffeine. Caffeine can also increase risk of stretch marks. Suddenly quitting coffee intake can cause headaches; so most experts recommend gradually reducing the amount consumed.

4. Drugs and Herbal Remedies - Always be careful about drugs or herbal remedies that are not prescribed by a doctor. These substances may affect the development of your unborn child.

5. Nutrition - Good nutrition is crucial to a developing child, particularly getting enough folic acid. Lack of folic acid can cause birth defects. At least 400-1000 micrograms of this B vitamin is suggested (about ten times more if you've already had a child with neural tube birth defects) starting one month before pregnant and throughout the entire pregnancy. Leafy vegetables, orange juice, and beans are some natural sources of folic acid. Many stores sell vitamins with folic acid.
