Transcript: If you’re pregnant, you may find yourself bonding with the toilet more than with your baby-to-be. What’s the deal with morning sickness, anyway? First of all, remember that morning sickness is a normal part of most pregnancies, particularly in the first trimester. You’re feeling nauseous and vomiting because your new pregnancy hormones, B. like progesterone, are elevated, a healthy sign that your pregnancy is progressing. But that’s not to say you should worry if you’re sailing through a pregnancy without being sick. Twenty-five percent of women are fortunate enough to avoid morning sickness. While that means that three-quarters of women do experience some morning sickness, it is usually more frequent and severe in women who…have experienced nausea while taking birth control pills…already suffer from motion sickness… are pregnant with multiple children at once…or who have first-degree female relatives who experienced morning sickness. If you’re sick of being sick, however, you’ll be happy to learn that some tried and true tricks can help ease this unpleasant symptom. Check out other videos in this series to learn about them.
