Smoking is one of the main causes of the development of many fatal diseases. According to WHO statistics, about 6 million people die from it every year around the world. The dangers of smoking cannot be overstated. When tobacco smoke enters the body, the conduction of nerve impulses, which are responsible for the state of most organs and systems, is disrupted. The consequence of smoking is the formation of multiple pathologies.

Of course, a complete rejection of tobacco products during pregnancy significantly reduces the risks of developing various pathologies from the fetus, and also reduces the risk of complications associated with pregnancy. True, at first the body of a pregnant woman will experience discomfort associated with the "breakdown" of the body against the background of a sharp cessation of smoking.

There are also many fetal pathologies that are not associated with smoking, therefore, with a complete rejection of tobacco products, you cannot be 100% sure that now everything will be great! It is necessary to be constantly monitored by a specialist who predicts in advance the likely risks to the fetus and the pregnant woman, monitors their state of health, and constantly prescribes the necessary studies.

All eggs are laid in girls during embryonic development, and after birth, not a single new one grows.

Smoking, and indeed any intoxication, contact with harmful substances, affects all these eggs, causing damage in some of them, including genetic material. Even with a small degree of regular toxic exposure, many of the violations provoked by it are irreversible. From which cell the child will subsequently grow is not known. To some extent - roulette. Considering that the peculiarity of the modern sphere of human habitation is the regular adverse effects of chemistry, as such, the inhalation of harmful aerosols, oil products, combustion, etc. sometimes even more significant than smoking itself.

In general, smoking before pregnancy can lead to irreversible changes in the safety of genetic material. Maybe, but not always.

However, the very fact of smoking can be caused by the genetic predisposition of the parents. But, for its implementation, epigenetic factors must be active, which make it possible to read this information. Therefore, there is a high probability of transmitting to the child both a predisposition to smoking and the possibility of realizing this addiction in him. Some epigenetic factors remain active and can be transmitted to offspring even 10-20 years after a person quit smoking. Epigenetics is a very young science that studies epigenetic inheritance, which, for all the complexity of its formulations, examines the factors transmitted to offspring that affect the readability of genetic material.

Therefore, on the female body, chronic intoxication can have irreparable harm to any stage, at any age, even if you then quit smoking, long before pregnancy.
