If the amount of red wine consumed during the first month of pregnancy is relatively small, it usually has less effect on the fetus and there is no need to worry too much and the pregnancy can continue. If a pregnant woman drinks more alcohol at one time with a higher alcohol content and drinks regularly, she must inform her doctor of the specific situation and choose carefully whether to continue the pregnancy. Alcohol can pass through the placenta into the body of the fetus and have an effect on the growth and development of the fetus, with the degree of effect varying according to the individual fetus’s alcohol sensitivity and the amount of alcohol consumed. If a pregnant woman has been drinking alcohol after pregnancy, it is more important for her to insist on regular labor and delivery tests. Down’s syndrome screening at 15-19 weeks of pregnancy or non-invasive DNA testing on an individual basis. Ultrasound screening around 22-24 weeks of pregnancy to check the development of the fetus in detail, focusing on whether the heart and nervous system of the fetus are well-developed and whether the size is consistent with the gestational week. If abnormal development is detected, the fetus should be further evaluated for chromosomal abnormalities and genetic counseling should be conducted to assess the prognosis. If no abnormality occurs, the pregnancy can continue. In addition, pregnant women should maintain a happy mood, strictly abstain from smoking and alcohol, and stay away from second-hand smoke; eat a light diet, eat more nutritious and easy-to-digest food; take appropriate walks and other sports, and avoid heavy physical labor.
