🌼 What Makes Twin Pregnancy Special?
Twin pregnancy means growing two babies together inside one womb. This makes your pregnancy more unique and sensitive than normal pregnancies. Some twins share the same:
- Placenta
- Amniotic sac
- Blood supply
Some twins have separate sacs and placentas, while others share one.
Because of these differences, doctors must watch the pregnancy more carefully.
Twin pregnancies are usually one of these types:
✔ DCDA Twins (Dichorionic Diamniotic)
- Two placentas
- Two sacs
- Least risky
- Scans recommended every 4 weeks
✔ MCDA Twins (Monochorionic Diamniotic)
- One placenta
- Two sacs
- Higher risk due to shared blood supply
- Scans recommended every 2 weeks
✔ Monoamniotic Twins
- One placenta
- One sac
- Highest risk
- Need very frequent monitoring
Each type has different medical needs — and only regular pregnancy scans can help track them safely.
🌟 Why Are More Scans Needed in Twin Pregnancy?
Doctors suggest more frequent scans so that they can detect any issues at the earliest stage. Let’s understand the main reasons:
⭐ 1. To Monitor Each Baby’s Growth Separately
In twin pregnancies, both babies may not grow equally.
Some babies receive more nutrition; others receive less.
This is called growth discordance.
Ultrasound scans check:
- Each baby’s weight
- Head and abdominal size
- Blood flow to each baby
- If one baby is falling behind
At Nisarga Diagnostics Bangalore, fetal growth scans are done with high-accuracy ultrasound machines to detect even minor growth differences early.
⭐ 2. To Check Amniotic Fluid Levels
Twin pregnancies can develop:
- Oligohydramnios (low fluid)
- Polyhydramnios (high fluid)
- TTTS (Twin-to-Twin Transfusion Syndrome)
- TAPS (Twin Anemia–Polycythemia Sequence)
These conditions can be dangerous if not detected early.
Frequent scans help catch these problems before they become serious.
Nisarga Diagnostics Bangalore is known among expecting parents for accurate pregnancy scan in Bangalore services.
⭐ 3. To Monitor Placental Health
The placenta is the babies’ life source.
In twin pregnancies, doctors need to monitor:
- Placenta function
- Placenta position
- Placental blood flow
- Placenta sharing between twins
An unhealthy placenta can lead to:
- Poor nutrition
- Low oxygen
- Slow growth
- Preterm birth
Doppler studies performed help doctors understand how well the placenta is working.
⭐ 4. To Detect Twin-Specific Complications Early
Twins have slightly higher chances of certain complications.
These are often detected only through ultrasound.
Some conditions include:
- Twin-to-Twin Transfusion Syndrome (TTTS)
- Growth restriction in one twin
- Shared blood supply problems
- Cord complications
- Preterm labor
- Preeclampsia risk
By doing scans every 2 to 4 weeks, doctors can catch these issues fast and start treatment if needed.
⭐ 5. To Monitor Heartbeat, Movements & Growth Together
Because two babies are inside, each scan helps doctors check:
- Heartbeat of each baby
- Movement patterns
- Position inside the womb
- Blood circulation
- Overall development
These details help ensure both babies are safe inside the womb.
⭐ 6. To Plan a Safe & Healthy Delivery
As the due date nears, scans guide the doctor to decide:
- Whether normal delivery is possible
- Whether C-section is safer
- If NICU support may be needed
- When the perfect delivery time is
Twin babies may need early delivery.
Frequent scans give doctors the information needed to plan a safe birth.
Cord loops do not happen because of how the mother sleeps, walks, exercises, or eats. They also do not occur due to stress, travel, or any daily activity. Parents cannot cause or stop the cord from wrapping, and there is nothing you did wrong if a nuchal cord is seen on the scan.
In most cases, these loops are harmless and resolve on their own as the baby continues to move. Doctors monitor the baby’s growth and heartbeat to ensure everything is normal, and usually no special treatment is needed.
🌸 Benefits of Frequent Scans in Twin Pregnancy
Frequent pregnancy scans offer many benefits:
- Early detection of risks
- Better tracking of baby growth
- Safe management of complications
- Peace of mind for parents
- Clear updates at every stage
- Safe delivery planning
For twin pregnancies, frequent monitoring = safer pregnancy.
