What is the height of the uterine fundus?

Most people don't pay much attention to the height of the fundus of the uterus, thinking that this is an issue that can be ignored. However, this issue actually needs to be taken seriously, because the height of the fundus of the uterus will directly affect whether the fetus can grow healthily in your uterus after pregnancy and give birth to a healthy baby. So, what is the height of the fundus of the uterus?

The uterus can be divided into three parts: the cervix, the uterine body, and the uterine fundus. The round convex part at the upper end is the fundus of the uterus, and the narrow part at the lower end above the entrance of the fallopian tube is the cervix. The part between the fundus and the neck is the uterine body. The thickness of the uterine fundus is generally 18 cm.

How to measure the height of the uterine fundus?

The fundus of the uterus gradually rises from the bottom to the top at the pubic symphysis, and by the end of this month, it may reach between the pubic bone and the navel. Pregnant women can feel the position of the fundus of the uterus by themselves. The height of the fundus of the uterus is about 18 cm and may reach your navel.

Generally speaking, you can start measuring the height of the uterus (uterine height) at 16 weeks of pregnancy. The growth pattern of uterine height is: during 16 to 36 weeks of pregnancy, the uterine height increases by 0.8 to 1.0 cm per week, with an average increase of 0.9 cm; during 36 to 40 weeks of pregnancy, it increases by 0.4 cm per week; after 40 weeks of pregnancy, the uterine height will not only stop increasing, but will decrease, because the fetal head has entered the pelvis.

If the uterine height is in the warning zone for two consecutive or three consecutive measurements, it indicates an abnormality; if the uterine height is low, it often indicates intrauterine growth retardation or malformation of the fetus; if the uterine height is high, it often indicates multiple births, polyhydramnios, fetal malformation, macrosomia, breech presentation, high floating fetal head, pelvic stenosis, cephalopelvic disproportion, and placenta previa.

The above is a detailed explanation of the height of the uterine fundus. It is a necessary step for pregnant women to go for regular prenatal check-ups after pregnancy, so that they can accurately measure the height of their uterine fundus. Otherwise, abnormal phenomena are likely to occur.
