As a result of polls it was revealed that some women smoking before pregnancy continue to do it even waiting for the kid. This sad statistics cannot but concern. Last century researches worldwide for the purpose of clarification of influence of smoking of mother on a fruit were conducted. Unfavourable result. Let's consider how smoking on pregnancy is reflected.
The negative impact of an addiction both on the course of pregnancy, and on health of the child is by practical consideration proved.
The first trimester
Formation of bodies and all systems at an embryo happens in the first three months of pregnancy. After that they already will only grow further. It is natural that negative factors, such as smoking, alcoholism, drug addiction, viral infections can influence this process. The abortion, dying down of a fruit and the child's birth with various uglinesses and pathologies can turn out to be consequence of an addiction during this period. It is proved that at abusing smoking this indicator more, than twice higher. But even if it did not occur, nicotine can cause violations in formation of bodies. As a result, at an embryo various pathologies of internals develop.
The second trimester
By the beginning of the fourth month of pregnancy the created fruit begins to receive oxygen and food through a placenta. The smoking women because of nicotine have a narrowing of vessels. It breaks placentary blood circulation. Because of it intake of oxygen in a placenta and, respectively, to an embryo decreases. The fruit hypoxia is a consequence of what that leads to pathologies of a brain and other bodies. It is also noticed that because of an addiction the pregnant women have an early maturing of a placenta, its functionality decreases.
The third trimester
On the third trimester at the smoking women early the ripened placenta begins to get out of a shape and to become thinner. Similar pathology leads to dying down of a fruit or premature permission from pregnancy. Statistically, stillborn children meet at the pregnant women who are not refusing smoking for 25% more often than at those who have no addiction. And if the woman smokes on a pack and more cigarettes in day, then this figure increases to 40%. Premature children most often lag behind in development the age-mates.
Besides, in a placenta the smoking women have a blood supply violation. It can lead to her premature otsloyka. Oxygen starvation of an embryo delays growth and formation of bodies and the systems of a fruit. It is noticed that the appetite of the smoking women is reduced. Therefore they eat less, and the fruit receives less necessary substances. Mental, physical and intellectual development of a fruit slows down.
Children of the smoking parents lag behind the peers on all indicators. Babies at the women who are not refusing an addiction during pregnancy have such diseases more often:
- "wolf mouth";
- "cleft lip"
- squint;
- heart diseases;
- Down syndrome;
- intellectual backwardness, etc.
If the woman wants to give birth to the healthy kid, then she has to refuse an addiction. When independently it is impossible to leave off smoking, it is worth addressing the expert. It is much better to do it even during planning of the child.
