Apart from missing your period, which every pregnant woman will experience, morning sickness is thought to be the most common of the various symptoms of pregnancy that can occur. While it is somewhat difficult to know for certain exactly how many women will experience morning sickness, most experts agree that it is very common. Some estimates suggest that anywhere from 50 to 80% of women will experience morning sickness. Most experts think that at least two thirds of women will experience one degree of morning sickness or another.
While morning sickness is a common experience for pregnant women, the way that women experience morning sickness can vary greatly from one woman to the next. Some women may truly experience “morning” sickness, where they feel nauseous in the mornings. However, it is only slightly more common for pregnant women to have morning sickness in the morning. Morning sickness can occur at any time of the day. For some women, morning sickness can last all day.
The degree to which a woman will experience vomiting due to her morning sickness can vary as well. Around half of all pregnant women will have some vomiting during their pregnancy due to morning sickness. Other women, who experience severe morning sickness accompanied by regular or severe vomiting may have a condition known as Hyperemesis Gravidarum. This serious condition is much less common than general morning sickness, however. Only around one to three percent of women who experience morning sickness will have this severe form of morning sickness.
Morning sickness is caused, it is believed, by the changing levels of hormones that take place in a woman’s body during pregnancy. For some women, the enhanced sense of smell they experience during pregnancy can trigger, if not cause, their morning sickness. Morning sickness is more common in women that have twins or multiples. Morning sickness is also more common if you have a history of nausea when taking birth control pills, or if you are susceptible to motion sickness. In fact, it is common for women with morning sickness to use motion sickness remedies, such as acupressure bands, to alleviate their morning sickness.
