Twin pregnancies are exciting but require extra monitoring. One common concern is abnormal twins growth on ultrasound. Early detection through sonography helps ensure the health and safety of both babies and the mother.
If you’re searching for a sonography test near me or a reliable sonography centre near by me, understanding the causes and treatment options can help you make informed decisions.
Abnormal twin growth happens when

One twin grows slower than the other, or
Both twins are smaller than expected for their age
Doctors usually detect this condition during routine ultrasound exams.
Growth discordance means there is a noticeable size difference between the twins.
A weight difference of 20–25% or more is usually considered abnormal.
IUGR occurs when one or both twins do not grow at a normal rate inside the womb.
This condition occurs in identical twins who share a placenta. One twin receives more blood than the other, leading to uneven growth.
Several factors can affect twin growth, including

Placental problems
Unequal blood supply between twins
Twin-to-twin transfusion syndrome
High blood pressure during pregnancy
Diabetes in the mother
Poor nutrition
Genetic or chromosomal conditions
Ultrasound plays a key role in diagnosis. Doctors look for:
Differences in fetal size and weight
Unequal amniotic fluid levels
Abnormal blood flow using Doppler ultrasound
Delayed growth over time
Regular scans help track changes and plan treatment early.
Most pregnant women do not feel symptoms. However, warning signs may include:
Reduced fetal movement
Rapid abdominal growth
Pregnancy-related complications
Always follow your doctor’s scan schedule in twin pregnancies.
Treatment depends on the cause and severity of the condition.
Common management options include:
Frequent ultrasound monitoring
Doppler studies to check blood flow
Bed rest and nutritional support
Medication to manage maternal conditions
Laser therapy for TTTS
Early delivery if the condition becomes severe
Doctors aim to balance fetal growth with pregnancy safety.
Not all cases can be prevented, but risk can be reduced by:
Healthy diet and hydration
Managing blood pressure and diabetes
Avoiding smoking and alcohol
Early detection greatly improves outcomes.
You should consult your doctor immediately if:
Ultrasound shows growth differences
Fetal movement decreases
You experience pregnancy complications
Timely care can save lives.
