Around 70-80 percent of pregnant women experience symptoms of morning sickness. This figure indicates that there are 20-30 percent of pregnant women who do not experience morning sickness throughout their pregnancy.

Other possibilities for the absence of morning sickness symptoms are the low levels of beta hCG in the body. Some associate low levels of beta hCG with the risk of miscarriage. However, this is not entirely accurate. Consult a doctor to know the condition of the fetus, pregnant woman.

One of the risk factors for the occurrence of morning sickness is stress. When a mother is very stressed during pregnancy, it can worsen nausea and vomiting. Usually, morning sickness is not too noticeable in pregnant women with good stress management.

Nausea and vomiting during pregnancy are often associated with the mother's eating habits before pregnancy. Mothers who follow a vegetarian or semi-vegetarian diet before pregnancy tend to have a lower tendency to experience morning sickness in the early stages of pregnancy. Source: KlikDokter
