Morning Sickness
What is morning sickness?
Morning sickness is nausea or vomiting that usually occurs during the first 20 weeks of pregnancy. More than half of pregnant women have morning sickness during the first trimester. It usually goes away by the second trimester, when the level of pregnancy hormones in your body falls.
When morning sickness is severe it is called hyperemesis gravidarum.
Why does it occur?
It is not understood why some women develop morning sickness, but hormones appear to be involved. Women with high levels of pregnancy hormones tend to develop this condition and have it in subsequent pregnancies. It is also more common among women who are pregnant with more than one baby (such as twins or triplets).
What are the symptoms?
The symptoms of severe morning sickness include:
How is it diagnosed?
We will review your symptoms and may do lab tests of your blood and urine. The urine may be examined for concentration and the presence of ketones (a substance that comes from the breakdown of body protein). We may examine you and use more blood tests to rule out other conditions that might cause vomiting.
How is it treated?
Your treatment may include changes in both diet and medications. If your morning sickness is severe, you may need to go to the hospital for IV hydration and/or medication.

More severe morning sickness can be treated with prescription medication. If your nausea is not responding to the above recommendations, call us to discuss medication.
