If you drink alcohol after pregnancy, first of all, it will affect the body of the pregnant woman, causing blood vessels to dilate and blood circulation to accelerate, which will increase uterine contractions and convulsions, leading to miscarriage or premature birth. Secondly, it affects the growth and development of the fetus. If you drink alcohol in early pregnancy, alcohol will stimulate the fetus, leading to fetal malformations or neurological problems, affecting the growth of the fetus, leading to mental retardation or mental problems after birth. Drinking alcohol in the middle and late stages of pregnancy can lead to fetal growth retardation or intrauterine fetal death. After pregnancy, you should pay attention to good eating and living habits, quit smoking and drinking, and have a balanced nutrition in the right amount.
