An estimated 70 to 80 percent of pregnant women experience morning sickness. It most commonly starts around week 6 of pregnancy and goes away by week 14 although some women continue to experience nausea later in their pregnancy. Morning sickness is the conversational name for nausea and vomiting experienced during pregnancy. The stereotype of morning sickness is a pregnant woman who throws up as soon as her feet hit the floor in the morning, but most moms report a variety of symptoms.
Some throw up frequently, some are nauseated all day, and some just have nausea triggered by certain smells or foods. Morning sickness most commonly begins around week 6 of pregnancy, although a few moms report feeling nausea as early as 4 weeks pregnant which is only 2 weeks after conception! Week 4 of pregnancy is around the time your period is due to start. Most women have a positive pregnancy test at 5 to 6 weeks pregnant which is typically 1 to 2 weeks after your period was due.
Symptoms may start out somewhat mildly around 6 weeks, get worse and peak around 9 to 10 weeks, and then decrease as you get closer to 12 to 14 weeks. For many expecting moms, morning sickness begins to improve around 12 to 14 weeks so around the start of the second trimester. Almost all mothers report that their symptoms are completely gone by 16 to 20 weeks, although up to 10 percent of women have nausea all the way up to delivery.
While morning sickness does not start earlier if you are carrying twins, it may be more severe once it does start. The theory is that pregnancy hormones — such as progesterone and human chorionic gonadotropin HCG that are produced by the placenta — are responsible for sickness in the first place. While it may be very uncomfortable or even downright miserable and disruptive to your daily life, the positive news is that morning sickness is very rarely harmful to you or your baby.
A study from the National Institutes of Health showed that women who experience morning sickness may be less likely to experience a miscarriage. Morning sickness may indicate a healthy placenta that is producing plenty of pregnancy-supporting hormones.
A very small percentage of women have an extreme form of morning sickness called hyperemesis gravidarum. This condition includes severe, uncontrollable nausea and vomiting that can result in weight loss, electrolyte imbalances, malnutrition, and dehydration.
It can be harmful to you and your baby if left untreated. Morning nausea usually peaks between weeks , and typically fades by the end of the first trimester. However, some women can experience it well into their second and even third trimester. If your morning sickness lasts beyond your first trimester, you may be more sensitive to the nauseating effects of hormonal changes during pregnancy.
Or you may just have a more delicate stomach. But it never hurts to bring up your morning sickness with your doctor. The pregnancy hormone hCG reaches its highest level around the same time morning sickness is most severe, and increases in the hormones estrogen and progesterone can make it harder for your body to digest food. In rare and severe cases of morning sickness, your doctor will work to ensure that you and baby are getting the necessary nutrition and hydration to stay healthy.
Some cases can be treated with pressure-point wristbands, like those worn to prevent motion sickness. In other cases you might need medication, bed rest or intravenous IV fluids to help reduce or eliminate symptoms.
