Nausea or morning sickness bothers many women during pregnancy, with up to 80 percent experiencing nausea and 50 percent vomiting. Although it's called morning sickness, it can happen at any time of the day. There is some good news, however. One large study from the Swedish National Birth Registry showed that older women were less likely to report morning sickness in the first trimester than their younger counterparts.
Morning sickness is thought to be caused by the many changes your body is going through, particularly the hormonal changes. It's most common in the first trimester, and most women can expect the symptoms to end by the time they are in their second trimester. Unfortunately some women experience nausea throughout their pregnancies. But fewer women who have morning sickness have miscarriages, so being sick does have its benefits.
Nausea is not fun, but it's not dangerous unless you become dehydrated or lose weight. Becoming dehydrated actually makes morning sickness worse, so it is important to stay hydrated even when the last thing you feel like doing is drinking. Eating small, frequent meals can also help hold off nausea, since some women find that hunger can be a trigger.
Call your health-care provider if you are unable to keep fluids down, are dizzy, vomiting frequently, have a decrease in urination or very dark urine, feel dehydrated, have headaches, feel confused, or have rapid heartbeats. These are signs of hyperemesis, a severe form of morning sickness that requires immediate treatment.
There are some other things that can help lessen morning sickness. Ginger has been shown to help, so ginger tea or lollipops may be a solution. Getting enough sleep, avoiding strong odors, skipping food that is greasy or spicy, eating and drinking at different times, eating cold food, eating something salty at the beginning of a meal, and eating enough protein can all help quell nausea.
