Q1: Why does fundal height sometimes differ from ultrasound weight estimates?
Fundal height measures external anatomical distance, which is influenced by maternal body mass, uterine fibroids, amniotic fluid volume, and fetal position (such as transverse or breech presentations). Ultrasounds assess internal fetal bone measurements, head circumference, and abdominal girth, providing a more reliable biometric calculation than a simple surface tape measure.
Q2: Does carrying a very large belly mean a C-section is mandatory?
No. A visibly pronounced belly does not require surgical delivery on its own. Obstetric teams evaluate pelvic capacity, fetal heart telemetry, cervix status, and estimated weight before recommending delivery interventions. Suspected fetal macrosomia only prompts discussions of scheduled cesareans when estimated fetal weight exceeds 5,000 grams in non-diabetic parents, or 4,500 grams when gestational diabetes is present.
Q3: How can expectant parents prevent severe diastasis recti during pregnancy?
While genetic connective tissue strength and multi-fetal pregnancies dictate much of the risk, pregnant individuals can reduce strain by practicing the log-roll technique when getting out of bed, avoiding repetitive unassisted crunches after the first trimester, and engaging deep transverse abdominis and pelvic floor muscles under the guidance of a pelvic health physical therapist.
