Dizziness, nausea, vomiting, and fatigue are common during the third trimester of pregnancy and are considered early pregnancy reactions. Most pregnant women have similar symptoms in the early stages of pregnancy. The occurrence of early pregnancy reactions is mainly related to the increase of chorionic gonadotropin level in pregnant women, poor rest and emotional stress of pregnant women. It is usually the most severe within 12 weeks of pregnancy and will be relieved significantly after 3 months. Early pregnancy reactions usually do not affect the development of the baby, but if it is a particularly severe case of severe pregnancy vomiting, hospitalization is also required because of the effects of this condition on the pregnant woman and the baby.
