Many thin women or women with narrow hips they think that when they get pregnant they will not be able to carry their pregnancy to term, and that the baby will probably come out earlier than expected. Others think that, when giving birth, a narrow pelvis will impede the passage of the child through the birth canal, and that finally the baby will have to be born by Caesarean section.
There are many myths on these issues, but also a part of the truth. We tell you if there really is a risk in childbirth due to a narrow pelvis.
It is not the same thinness as narrow pelvis. You can be thin but have a wide pelvis, and in principle neither of these are a problem when giving birth.
The pelvis is made up of several bones at the end of the back, and it houses the baby during 9 months of gestation. Some women think that if you have a narrow pelvis, the baby will not have room to grow, so, in addition to coming out early, it will not be able to be born naturally either, but through a cesarean section.
The truth is that this is not exactly the case, since a priori there are no narrow hips until delivery. The pelvis adapts little by little throughout the pregnancy, and it dilates as the baby grows. On the other hand, the baby also helps the process, adapting to the shape of the pelvis.
At the time of birth, the pelvic bones dilate, forming the birth canal where the baby will descend, so the important thing is not so much the size of the pelvis as if the dilation is sufficient. Only in the event that the woman do not delay a cesarean section will be performed.
We must break the myth that women who measure less than 150 cm have a higher risk of suffering premature birth, since throughout history women have been shorter than now, which has never been a problem, and most of them gave birth naturally.
What must be taken into account is the baby proportion with respect to the pelvis. That is, even if we have a normal size pelvis, it may be that our baby is excessively large or heavy and the dilation opening is not enough for the baby to come out through it. In these cases, what must be taken into account is the parental genetics, since if the parents are very tall or wide, it is normal for their baby to be too. The problem would come if the mother is short and the father very tall, and the baby takes the genetics of the father, in that case there may be a risk of premature birth.
In reality, only one in 250 women has a narrower pelvis than normal.
There are exercises that help make the pelvis more flexible, such as Arabic dance, or yoga for pregnant women, and at the time of delivery it is best give birth squatting, since it is the way in which the pelvis is more open to allow the baby to pass.
