1.* Maternal health status *: The overall health status of the mother has an important impact on the development of the fetus. For example, if the mother suffers from hypertension, diabetes, heart disease or other chronic diseases, these diseases may affect the health of the fetus. In addition, the nutritional status of the mother will also affect the development of the fetus, including the intake of protein, vitamins, minerals and other nutrients.
2.* Lifestyle *: Smoking, drinking, using illegal drugs or exposure to harmful environment (such as certain chemicals, radiation, etc. ) may have a negative impact on the health of the fetus. In addition, excessive stress and lack of exercise may also affect the health of the fetus.
3.* Genetic factors *: The genetic factors of both parents will also affect the health of the fetus. For example, if one or both parents have a genetic disease or chromosomal abnormality, it may be passed on to the fetus.
4.* Infection *: Some infectious diseases, such as rubella, cytomegalovirus and toxoplasmosis, may have a serious impact on the health of the fetus if they are infected for the first time during pregnancy.
5.* Drugs and treatments *: Some drugs and treatments may affect the health of the fetus. Therefore, if you are receiving any medication, please be sure to tell your doctor that you are pregnant.
6.* Age *: The age of the mother is also an important factor. Generally speaking, children born to mothers over the age of 35 are more likely to have chromosome abnormalities than children born to young mothers.
All the above factors may affect the healthy development of the fetus, but not all factors will affect every child. Everyone's situation is unique, so it's best to work closely with doctors to ensure the health of you and your children.
