Morning sickness or nausea, sometimes comes with vomiting, is caused by pregnancy hormones during the first trimester of pregnancy, and sometimes begins as early as two weeks after conception. Some women find that nausea and vomiting are worst in the morning. But symptoms can occur at any time of day or night. Most women feel better at the beginning of the second trimester (around the 12th- 14th week), while some others continue to feel ill throughout their pregnancies.
Morning sickness affects a large proportion of pregnant women though it tends to be worse in first-time pregnancies. Morning sickness can range from mild, occasional nausea to severe, continuous, and disabling nausea with bouts of vomiting. Rarely do pregnant women get morning sickness that is so severe that it may require hospitalisation and treatment.
What causes morning sickness during pregnancy?
Early in pregnancy, hormone levels (pregnancy hormones hCG and estrogen) increase dramatically causing that nauseous feeling as the body is not yet used to the new hormone levels. Also women carrying twins or more have higher hormones levels and tend to have severe morning sickness.
Increased levels of progesterone make the muscles of the digestive tract more relaxed which slows digestion and make the stomach take more time to empty.
Pregnant women develop a heightened sense of smell, making previously mild odours strong enough to cause vomiting.
Skipping meals and pregnancy food aversions could also contribute to the nauseous feeling.
How to cope with morning sickness
Opt for foods that may help:
Consult your Ob-gyn if the nausea or vomiting is constant or so severe that no fluids or foods are kept down, and if it is causing dehydration or weight loss, or in case the morning sickness is accompanied by pain or fever or dizziness and fainting or blood vomiting or passing small amounts of dark urine. Some severe cases of morning sickness could require prescribed medicines or hospitalisation.
