Guide | Monitoring Fundal Height to Track Fetal Health
Pregnancy is an exciting and remarkable process, and many expectant mothers wonder how their baby is growing in the uterus. Measuring fundal height is a common way to monitor fetal development.
What is fundal height?
Fundal height is the distance from the upper edge of the pregnant woman's pubic bone to the top of the uterus. It is an important indicator of fetal development and is usually measured at every prenatal visit. Doctors also assess fetal health by listening to the fetal heartbeat, checking fetal movement, performing ultrasound examinations, and using other methods. Together, these factors provide a more accurate picture of the baby's growth.
What does fundal height indicate?
Doctors use fundal height to assess fetal growth. It is one of several measures used to determine whether development is progressing normally. Fundal height generally correlates with gestational age and should align with the number of weeks of pregnancy. A measurement within the expected range usually indicates that the baby is growing as expected. An unusual measurement does not necessarily indicate a problem, as many factors can affect it; the doctor will perform further evaluation as appropriate.
How is fundal height measured?
Although measuring fundal height may appear simple, even trained clinicians can sometimes find it difficult. Before trying it yourself, ask a doctor to show you how to locate the pubic bone and top of the uterus accurately.
Measurement steps:
Empty the bladder: Studies show that a full bladder can alter the measurement by several centimeters.
Lie flat: Lie on your back with your legs straight.
Measure: Place the zero mark of a flexible metric tape at the top of the uterus, extend it vertically down the abdomen, and place the other end at the upper edge of the pubic bone. This distance is the fundal height.
What should fundal height be?
From 24 weeks, fundal height in centimeters should be approximately equal to gestational age in weeks. At 30 weeks, for example, it is typically 28 to 32 cm. A difference of up to 2 cm remains within the normal range.
What can affect fundal height?
Many factors besides fetal growth can affect fundal height measurements. Measurements may be less accurate if:
The pregnant woman's body mass index (BMI) is above 30;
She has a history of uterine fibroids;
Her bladder is full;
She is not lying flat during measurement.
A larger-than-expected fundal height may result from:
Excess amniotic fluid;
A multiple pregnancy;
A baby larger than expected.
A smaller-than-expected fundal height may result from:
A baby smaller than expected;
Low amniotic fluid;
Fetal growth restriction.
An incorrect estimate of gestational age can also affect the measurement.
What if there are concerns about fundal height?
If fundal height differs from expectations, the doctor will usually perform follow-up testing, including an ultrasound or physical examination, to determine the cause. An unusual measurement can sometimes signal a fetal health concern, but it is not always a reason for alarm. The doctor will tailor follow-up examinations and treatment to support healthy fetal development.
Conclusion
Fundal height is a common prenatal monitoring tool that helps doctors assess fetal growth and identify potential concerns promptly. Understanding how it is measured can help expectant mothers work with their doctors to monitor healthy fetal development.
