1. What is Fundal Height Measurement?

Fundal height measurement is a clinical assessment technique used during pregnancy to estimate fetal growth and gestational age by measuring the distance from the pubic bone to the top of the uterus.

2. How Does the Calculation Work?

The calculation uses a simple formula:

Where:

• Fundal Height — Measured in centimeters from pubic symphysis to top of uterus
• Gestational Age — Pregnancy duration in weeks
• ± 2 cm — Acceptable normal variation range

Explanation: After 20 weeks of pregnancy, the fundal height in centimeters typically corresponds to the gestational age in weeks, with a normal variation of ± 2 centimeters.

3. Importance of Fundal Height Measurement

Details: Regular fundal height measurements help monitor fetal growth, identify potential issues like intrauterine growth restriction or polyhydramnios, and provide a simple, non-invasive way to track pregnancy progression.

4. Using the Calculator

Tips: Enter the current gestational age in weeks (typically between 20-42 weeks for most accurate results). The calculator will provide the expected normal range of fundal height measurement.

5. Frequently Asked Questions (FAQ)

Q1: When should fundal height measurements begin?
A: Fundal height measurements are typically started around 20 weeks gestation, when the uterus reaches the level of the umbilicus.

Q2: What factors can affect fundal height measurements?
A: Maternal body habitus, multiple gestation, uterine fibroids, fetal position, and amniotic fluid volume can all affect fundal height measurements.

Q3: What does it mean if fundal height measures outside the expected range?
A: Measurements significantly outside the expected range may warrant further investigation with ultrasound to assess fetal growth and amniotic fluid volume.

Q4: How accurate is fundal height measurement?
A: While useful for screening, fundal height measurement has limitations and ultrasound remains the gold standard for accurate fetal growth assessment.

Q5: Who should perform fundal height measurements?
A: Fundal height measurements are typically performed by healthcare providers including obstetricians, midwives, and trained prenatal care providers.
