Nausea, sometimes accompanied by vomiting, is an unpleasant side effect of pregnancy. Sixty to eighty percent of all pregnant Western women experience this nausea, or ‘morning sickness,’ with half of these experiencing vomiting as well. Despite its common name, morning sickness can occur at any time of the day.Nausea is usually limited to the early weeks of pregnancy, beginning in the first 4 to 16 weeks and disappearing by 14 to 17 weeks after a woman’s last menstrual cycle.
Researchers have developed theories about why it occurs, but to date no specific cause has been identified. Some suggested causes include hormonal changes and the stress and anxiety of becoming pregnant. Despite the discomfort of morning sickness, it is usually not dangerous to the mother nor fetus. In fact, research shows that women who experience morning sickness have better outcomes of pregnancy including decreased incidence of miscarriages.
However, if nausea and vomiting are persistent, severe, and prolonged, medical treatment may be necessary. This condition, also known as hyperemesis gravidarum, occurs in two percent of pregnant women and can result in electrolyte imbalance, dehydration, and nutrient deficiencies which can affect your pregnancy. It is important to quickly report severe nausea or vomiting that affects your ability to eat to your physician.
Although uncomfortable, most cases of morning sickness are easily treated with small dietary and environmental manipulation. There is no universal cure, as the cause is yet unknown and each women reports different triggers. It may also be helpful to keep a journal of your symptoms and day to day activities to help pinpoint when your symptoms are absent or severe. This can help you, and your physician, understand your triggers and help in developing strategies to minimize nausea.
