During your antenatal visits, the same gesture is repeated: the midwife or the gynecologist releases her tape measure and, like a seamstress, measures the height of your belly bounced. A way to "measure" the smooth progress of your pregnancy.

The uterine height "measures" the good growth of your baby

  • The uterine height is the distance between the pubic symphysis (one of the pelvic joints that you feel when you touch pubic hair) and the uterine fundus (the uppermost part of the uterus), both evaluated by palpation.
  • " Pregnancy month is four times the average uterine height. For example, at seven months of pregnancy, it is 7 times 4, that is 28 centimeters. It is then compared to what is actually measured, "says Myriam Carette, midwife.
  • It is important that it is always the same person who does this since this gesture depends heavily on the taking of landmarks.
  • But beware, the height of your belly sometimes depends on the position of your future baby ! A baby in a transverse position can decrease uterine height, as can a baby who tends to be low in the uterine cavity. If in doubt about the correct growth of your child, your belly will be closely monitored.

What happens if the uterine measurement is too weak?

  • If the practitioner suspects intra-uterine growth retardation, he may decide to hospitalize complete or day. He will also prescribe exams, including an ultrasound, to be reassured about the well-being of your future baby.
  • Low uterine height sometimes reveals a small amount of amniotic fluid or oligo-amnion (4% of cases). "For the baby, this deficiency characterizes an intrauterine growth retardation and is also likely to have consequences on its lung development," says Professor Dominique Cabrol, a gynecologist-obstetrician.
