One of the biggest unknowns in the process of gestation of a baby is how much it grows inside and what weight it is bearing as the weeks go by
In each ultrasound the gynecologist takes some measures that offer a fairly reliable orientation on the weight of the baby, at which time the parents' doubts dissipate until the next visit.
To avoid this uncertainty, there is a calendar that specifies, week by week, the weight of the fetus, the abdominal circumference, the cephalic circumference (of the head) and the length of the femur.
As an addition, it has the data of the mother's weight gain, also week by week. Obviously it is an average and therefore does not mean that it is mandatory.
For example, the calendar indicates that after 40 weeks the total weight gain in the mother is 10,150 grams and I have found another publication that marks the total average at 12.6 kg. I leave the latter data as curiosity :
Average weight gain of the mother
- Blood volume: 1.3 kg Breasts: 0.4 kg Uterus: 1 kg Fetus: 3.4 kg Placenta: 0.7 kg Amniotic fluid: 0.8 kg Fat: 3.5 kg Retained liquid: 1.5 kg ( can reach 4.5 kg) Total: 12.6 kg
Legend of the calendar abbreviations:
- APMadre: Weight gain of the mother's weight.
- Pfeto: Weight of the fetus.
- CircAbdom: Abdominal circumference.
- Cephalic: Head circumference.
- Femur: Femur length.
