First of all, women's physical condition and genetic differences may lead to different resistance to alcohol and tobacco. Some women may be more sensitive to the harm of tobacco and alcohol, and are vulnerable to more serious health effects. At the same time, long-term smoking and drinking may have adverse effects on the female reproductive system, such as irregular menstruation and ovulation disorder, which will affect the chances of pregnancy and the health of the fetus.
Secondly, nicotine and alcohol in tobacco may affect eggs, leading to abnormal embryonic development or gene mutation. If you continue to smoke and drink during pregnancy, it may also cause damage to the nervous system and organ development of the fetus, increasing the problems of fetal malformation and growth restriction.
However, for some women, even if they have the habit of smoking and drinking, they can still have healthy children. This may be because their physical fitness is better and they can resist some injuries caused by alcohol and tobacco, or their genes are more resistant to alcohol and tobacco.
Generally speaking, although some women can still give birth to healthy children while smoking and drinking, this does not mean that smoking and drinking are harmless to all women. In order to ensure the fertility of women and the health of the fetus to the greatest extent, it is suggested that women should avoid smoking and drinking as much as possible during pregnancy. If you can't quit, it is best to carry out family planning under the guidance of a professional doctor.
