Doctor's answer:

Hello:
Pregnancy is like a woman using her own body to provide fertile ground for the fetus of both partners. A woman's physical condition directly affects the implantation of the fertilized egg and the healthy growth of the embryo. For example: If a woman suffers from anemia or malnutrition before pregnancy, it will directly hinder the healthy growth and development of the fetus in her body during pregnancy. In daily life, we often see newborns with low birth weight, anemia, malnutrition, and incomplete brain development, most of which are caused by these reasons.
For women to smoothly pass through the gestation period and give birth to a healthy baby, they must have a healthy physique. Therefore, the following diseases should be completely cured before pregnancy:
　　【Vaginitis】： Most commonly caused by Candida infection, it can infect the fetus during childbirth and easily lead to thrush in the infant.
　　【Tuberculosis】： This is a terrible disease for pregnant women. It can be transmitted to the infant, and if pregnancy occurs during an open phase, there is a risk of premature birth or stillbirth.
　　【Heart and Liver Disease】： While a healthy person's heart burden increases after pregnancy, those with heart and liver disease face a heavier burden. As the delivery approaches, heart and liver dysfunction and circulatory disorders may occur, leading to abnormal placental blood vessels, resulting in miscarriage or premature birth. Heart and liver disease is also the cause of pregnancy toxemia, so heart disease must be cured before pregnancy.
　　【Kidney Disease】： Once pregnant, those with this disease are prone to pregnancy toxemia, which not only severely affects the fetus but also endangers the life of the pregnant woman.
　　【Hypertension】： Similar to kidney disease patients, they are also prone to pregnancy toxemia.
