Patient's question:
Alcohol consumption during early pregnancy mainly has what adverse effects on the fetusDoctor's answer:
Hello, pregnant women drinking alcohol has a very high risk of fetal malformation. Excessive alcohol consumption during pregnancy can cause "fetal drunkenness" and lead to "fetal alcohol syndrome." The infant may suffer from multiple deformities, developmental delays, and intellectual disabilities. Therefore, it is absolutely essential to avoid alcohol during pregnancy, especially in the early stages. It is recommended to undergo further medical examination and handle the situation with caution.The first trimester of pregnancy refers to the period from 1 to 3 months after conception. This stage is when the "future baby's" important tissues and organs begin to differentiate. It is the most sensitive period to external adverse stimuli and has the highest incidence of fetal malformations. Generally, ovulation occurs around the time between two menstrual periods. Therefore, conception often happens about two weeks after the last menstrual period.
Since the exact date of conception cannot be determined, clinical practice calculates the start of pregnancy from the first day of the last menstrual period. In reality, the gestational age is about two weeks less than the period of amenorrhea.
At two weeks of gestation (which corresponds to four weeks after the last menstrual period), since the menstrual period has not yet exceeded one month, most people are not aware that they are pregnant. During this two-week period, the embryo has not yet differentiated into the head, torso, limbs, and internal organs. If anything adverse occurs to the fetus during this time, severe cases may lead to embryonic death and subsequent natural miscarriage, which the patient may not notice.
Wishing you good health!
