Morning Sickness - MacArthur Medical Center

Most pregnant women will experience “morning sickness” which is the feeling of nausea during pregnancy. About one third of women will also experience vomiting.  The term morning sickness can be misleading  as most women experience nausea throughout the day and not only in the morning.

Morning sickness is very common and usually occurs in the first trimester (13 weeks) of pregnancy. For most women, it begins during the first month of pregnancy and begins to resolve at the beginning of the second trimester (14-16 weeks).  Some women have nausea and vomiting through their entire pregnancy.

While morning sickness is one of the more bothersome pregnancy symptoms for moms, it does not hurt the baby in any way unless it becomes severe.  Mild weight loss during the first trimester is expected in women with morning sickness as well as from other dietary changes and possible food aversions.

The experience of morning sickness during one pregnancy does not necessarily predict how you will feel in subsequent pregnancies.


The cause of nausea and vomiting in pregnancy is multi-factorial. It can be caused by hormone changes associated with pregnancy and lower blood sugar during early pregnancy. Situational causes also exist such as fatigue, emotional stress, and some foods and lack of food can make the problem worse. Morning sickness is more common and can be worse with multiple pregnancy (twins or triplets).

  • Eat or drink Ginger products: Ginger candy, soda, or tea. Grating fresh ginger root makes for a very effective ginger tea
  • Try keeping sour candy in your purse or pockets, for some women sour candy can relieve nausea.
