Disorders that may occur in the pregnant smoker are directly proportional to the number of cigarettes smoked. It also influences the stay in places where the surrounding environment is polluted by smoke snuff. One thing that has been observed in many women smokers is that the placenta of these is much greater than those that do not smoke during pregnancy or have never smoked.
This response is defined as compensation to offset the lack of oxygen induced by maternal smoking. To be greater the size of the placenta in these women, the frequency of placenta previa with greater risk of abruptio placenta, bleeding of the same and early rupture of membranes. All of these complications occur more frequently in those smokers who have a high level of consumption.
Several studies have confirmed that the incidence of placental complications is higher in pregnancies of women who smoke than in those who are not.
These complications carry a high risk of preterm birth and fetal or neonatal loss are related as cause of death in deaths related to the birth of the children of smoking mothers.
The cessation of snuff when pregnancy is confirmed, puts these women in a situation almost similar in terms of harm to the fetus is concerned, that of women who never smoked. The fact observed by most gynecologists is that children of mothers who smoke weigh on average at birth between 150 and 250 g less than those infants whose mothers did not smoke.
In female smokers who quit smoking during pregnancy, the weight of their children is identical to the children of those who have never smoked. Although not yet known exactly what is the time when the consumption of snuff is more detrimental to the final weight of the newborn, it seems more evident in the third trimester of pregnancy, a period in which oxygen demand is greater and more urgent.
