The health of a child after pregnancy has nothing to do with the presence or absence of pregnancy vomiting during pregnancy, but is mainly due to individual differences. Some people are not sensitive to the rise in estrogen and do not experience nausea or vomiting, and the child they have will also be healthy. Therefore, the health of the child has nothing to do with the presence or absence of pregnancy vomiting. When the blood HCG rises after pregnancy, the majority of women will experience nausea and vomiting and other early pregnancy reactions. It is recommended to give regular checkups during pregnancy, and give timely treatment if abnormalities are found, and also strengthen nutrition during pregnancy.
