Pregnancy / Childbirth

Big weight gain in pregnancy = big baby?


You may hear that the more you gain weight during pregnancy, the larger the baby will be after delivery. However, is that really true? What determines how big a baby is born and do you, as a future mother, influence your baby's birth weight?

Big weight in pregnancy

Just because you have taken a lot during pregnancy does not necessarily mean that the baby is also big. Whether your toddler will be larger or smaller depends much more on:

  • genetic conditions,
  • mother's birth weight (if it was high, the child could also be large)
  • pre-pregnancy weights (heavier women often give birth to heavier children)
  • diet (it is worth ensuring a good diet during pregnancy, without empty calories)

Relationship between mother's weight and baby's weight

There is no rule, although the rule is that the higher the weight of a pregnant woman, the higher the child's weight.

Expectant mother may have effect on fetal weight. First of all, let the child not be born underweight you should opt out of alcohol, cigarettes, reduce stress (read stress in pregnancy). any medicines (including vitamins !!!) should be taken only after consulting a doctor. good nutrition during pregnancy (read) can also help the child's development process. Also lifestyle: movement, walking in the fresh air, skillful calmness and relaxation supports the well-being of the fetus, including its proper development.

Unfortunately, the risk that exists and can affect the weight of the fetus cannot be eliminated. First of all, the low weight of the fetus and, on the other hand, too high can be the result of diseases that pass through the mother's pregnancy or directly affect the fetus.

How to assess the weight of the child in the mother's stomach?

In the past, before the introduction of ultrasound examinations on a large scale, the doctor could to some extent assess the child's weight through examination of the pregnant belly and determination of the height of the bottom of the uterus at certain stages of pregnancy. Today, for this purpose, an ultrasound scanner is used, which, however, does not provide 100% certainty that the result after delivery will be confirmed. 10% high margin of error.

Is a big child harder to be born?

Contrary to what intuition suggests, the relationship is not so simple and obvious. Of course, theoretically, giving birth to a 3-3.5 kg baby may seem easier than what weighs 4 kg, but in practice it is much more complicated.

Most often, what the delivery will look like can be assessed by whether the head will be able to pass through the birth canal in the mother's pelvis. Most often, newborns are well adapted in size to the size of their mothers and their pelvis. Therefore, contraindication to natural delivery in the form of inadequate pelvic structure is rare.

And you, how big children were you born? Did you expect such a weight?
