Pregnancy sickness is the most common medical condition of early pregnancy, but how bad it varies widely from woman to woman. You may get the odd bout of mild queasiness when you first wake up or find that certain smells trigger waves of nausea throughout the day. You may have to endure weeks or even months of feeling or being sick morning, noon and night.
The number of times one may vomit is dependent on one’s individual condition and health and as such, there is no such number which can be considered as normal or otherwise. The most severe form of pregnancy sickness is called hyperemesis gravidarum (literally "excessive vomiting in pregnancy"). If you are vomiting many times a day, are unable to eat and drink without vomiting, and if you are losing weight then you probably have hyperemesis. Unlike normal pregnancy sickness, hyperemesis can affect your health and that of your baby, so talk to your doctor or midwife as soon as you can help you. More than two-thirds of women will experience nausea and vomiting during the first trimester (Week 1 to week 12) of pregnancy. For the vast majority of these women, however, this nausea and vomiting, sometimes also referred to as “morning sickness,” will pass by the time the second trimester (week 13 to week 26 or months 4 to month 6) begins, never returning. However, nausea and vomiting returning during the second trimester are not entirely unheard of.
If you have had nausea and vomiting returning during the second trimester (month 4 to month 6), it is important that you try to find out what exactly is causing nausea and vomiting. Certainly, it is possible that it is just your morning sickness returning. However, morning sickness is, most experts believe, caused by the changing levels of hormones in your body that take place during pregnancy. By the time your second trimester rolls around, these hormone levels have typically begun to stabilize.
One possible cause for a return of nausea and vomiting during the second trimester is a condition known as hyperemesis gravidarum. Hyperemesis Gravidarum is a condition that sometimes afflicts pregnant women, and its symptoms include severe nausea and vomiting. Hyperemesis gravidarum is generally treated with changes in diet, rest, and sometimes antacids. In general, anti-nausea medications are to be avoided during pregnancy.
If your nausea and vomiting are not severe or prolonged, you may be able to treat them with a variety of natural methods. You might try some ginger extract supplements or ginger tea. You might make a point to avoid fatty or spicy foods. You should eat several small meals, to avoid becoming too hungry or too full during the day. Finally, you should avoid strong odors if possible, as the enhanced sense of smell that many pregnant women experience can be responsible for nausea and vomiting.
If you are experiencing severe nausea and vomiting during the second trimester, or if your nausea and vomiting last for more than 24 hours during the second trimester, you should contact your health care provider. It could be any number of things, from a simple stomach virus to a serious condition such as hyperemesis gravidarum, that is causing your nausea and vomiting.
