It's been widely reported that women who experience morning sickness have a statistically lower risk of miscarriage. Does that mean women who have no nausea or vomiting should be worried about a higher risk of miscarriage?


Lack of morning sickness is not considered a symptom or risk of miscarriage. In fact, about one third of pregnant women in Western cultures do not report any symptoms associated with morning sickness. Plus, there are at least seven traditional societies known of a lack of morning sickness among pregnant women.

While not definitive, researchers of these cultures believe dietary differences are a reason pregnant women do not experience nausea or vomiting. They share eating a plant-based, whole food diet.

Having concerns about a lack of morning sickness is just another reminder not to over-analyze pregnancy symptoms. Fluctuations in pregnancy symptoms are normal and there is a huge variation among women.


Morning sickness, a.k.a. the nausea and vomiting that typically occurs during the first three to four months of pregnancy, usually disappears on its own. However, it is still normal for morning sickness to occur at any point during pregnancy and usually poses no risk for the mother or fetus. Most expectant mothers experience nausea at some point during their pregnancy, with or without vomiting.

Morning sickness can become a more serious problem, known as hyperemesis gravidarum, when the mother has severe vomiting on a daily basis that causes dehydration and considerable weight loss (loss of 5 percent body weight). However, a little weight loss during the first trimester can be normal.


Doctors believe that many factors may contribute to morning sickness such as hormone changes experienced during pregnancy or low blood sugar levels.

Many pregnant women experience morning sickness, many others have perfectly healthy pregnancies without any nausea at any point. It's uncertain why some women feel sick and others are spared this symptom.

If you are pregnant and do not experience morning sickness, consider whether diet may be a positive influence and count this a blessing. Just be sure to address lingering concerns with a healthcare practitioner.


Fortunately, many expectant mothers can find relief from the uncomfortable symptoms of morning sickness through dietary changes.

Here are some tips doctors advise :

  • drink plenty of fluids;
  • eat 5 to 6 small meals each day;
  • remember the acronym BRAT, it stands for bananas, rice, applesauce and; toast; foods to reduce vomiting;
  • have a little food as soon as you wake up and before you go to bed;
  • try ginger candy, capsules or tea to decrease nausea;
  • speak with your physician about taking vitamin B6 supplements;
  • try consuming bland foods when nauseated, like broth, gelatin or crackers;
  • try motion sickness wristbands or acupuncture.

If these tips do not work, doctors can prescribe medications for nausea such as Zofran (ondansetron) or Unisom (doxylamine succinate). Newer anti-nausea medications (Diclegis and Bonjesta) combine vitamin B6 and doxylamine succinate into one pill.
